Meyer Plow Wiring Diagrams

Help identifying what you need the diagram for


I regularly review what web sites sent visitors to our web sites, and what keywords or phrases those visitors were searching that brought them to one of our many Meyer Plow web sites.

Some of the most common ones I see are:

Now, all of the above diagrams are here on our web sites, or we have links to them on our sites, but you have to know exactly what you are looking for. If you don’t know, you are just wasting your time, or might get lucky, and find what you need. Another thing people say when they call asking for help, are things like “I have a Meyer E-47 Plow”, or “I have a Meyer E-60 Plow”. Now, this is where the “have to know exactly what you have” I mentioned above comes into play. I am quick to correct the callers, pointing out that the Meyer E-47, and the Meyer E-60 are just pumps. That is just one part of a complete plow system.

Hopefully this new page will put it all into perspective. It is going to be long, but you WILL find the help you need. YOU just have to take the time to read. Unless you like paying someone else to fix everything (which I do not think is the case) it is in your best interest to spend the time required to identify what you have. The good news is you can write it down once figured out, and never have to wonder again. So that is why there are mounts, Moldboards, Lift Frames, etc. on this page. You MUST know most of this before you can locate the wiring diagram you need. The age and mount style dictates which diagram you are going to need, as does the hydraulic unit model number, and brand of plow lights, which controller you have, etc. So not only do you need to know what you have to find wiring info, you will need to know what you have to order ANY repair parts.

Now there are always going to be a few exceptions, but overall, you need to know the various components of the system you have, because it makes a difference when it comes to parts, and looking for technical help with your Meyer Plow. I recall at a regional meeting with Meyer Products back in 2007, they offered 60+ combinations of plow systems. That’s right, OVER 60! Today it has been trimmed down to over 30. That is still an incredible amount of combinations, but, to stay competitive, all manufacturers need to offer a flavor for everyone.

The main components of a complete Meyer Plow system are:

The Mounting Carton, the Hydraulic Unit, the Moldboard, the Light System, and the Controller. Before looking for technical information to help you solve the problem you are having with your Meyer Plow, you need to identify which of the aforementioned components you have.

You can have an EZ Classic mount, with the E-47, E-57, or E-60 pump. You can have an EZ Classic Mount with any of the aforementioned pumps, and Truck Lite plow lights, or Nite Saber plow lights, or maybe a previous owner installed a set of older Dietz plow lights. You may have an ST Moldboard, or a C Series Moldboard, or a Diamond Moldboard. You may have Toggle Switch Controls, or a Slik Stik, or a Touchpad. ALL of these light systems and control systems have their OWN specific wiring. So saying or thinking you have an “E-60 Meyer Plow” is not really helpful. Don’t worry, after reading this page you will be able to figure out exactly what you have.


So lets start with the Mounting. Over the years there has been a progression of designs, with some overlapping. So we will start at the beginning.

Custom Classic, also know as EZ Custom. This was the mount where the whole thing was made out of angle iron, and the Lift Frame was mounted behind the vehicle bumper. There was nothing you removed in the off season. Some smarter owners would remove their pumps, but overall, it ALL stayed on the truck except for the Moldboard.  The ENTIRE mounting was vehicle specific. There was no easy modification to make a mount from a Ford fit a GM, or a Dodge to fit a Ford, etc. This is the style of mount that was used from the 1950’s all the way up until 1991 when the EZ Classic mounting came out.

EZ Classic is often referred to as the “tube mount” in that it has two receiver tubes that the tubular Lift Frame slides into, secured with pins. The Lift Frame with the pump and lights can be removed in the off season ,and it was encouraged that it be removed in the off season. Like the EZ Custom, the Mounting Cartons were vehicle specific. so again, you could not modify a Ford Mounting Carton to fit a Dodge, or a Jeep Wrangler Mounting Carton to fit a Jeep Cherokee, not easily anyway. The Lift Frame however was universal in that there was one Lift Frame for all Fullsize trucks, and one for all downsized trucks (think Ford Ranger, Chevrolet S-10, Jeep Cherokee), and finally a third Lift Frame that only fit the Jeep Wrangler. It came out in 1991, and was discintnued as a complete new system in 2009.

Next was the MDII (Meyer / Diamond 2) mounting system. This is the first time that the entire “plow assembly” was universal. The system used a Universal Clevis on the vehicle that the plow assembly would connect to. This Universal Clevis was bolted to the Mounting Carton brackets attaching it to the truck frame. Now, while the Mounting Carton was vehicle specific, the same Universal Clevis was used on all Fullsize trucks. There was never a downsized version of the MDII. The MDII was used with the Diamond trip edge Moldboards, as well as the ST Series, and C Series Moldboards. The MDII had 3 pins on each side of the mount. Disengaging the Yellow handle pins would drop just the Moldboard off the vehicle, much like the EZ Custom and EZ Classic. Only disengaging the two Blue handled pins on each side would drop the whole assembly off the vehicle resting on the cutting edge of the Moldboard, and the Crankstand. the Crankstand allowed the height of the assembly to be adjusted to make mounting easier. So if you dropped the plow assembly with the truck loaded, and a week later went to hook up, with the truck unloaded, a few turns of the crank would move the assembly to the correct height to mount it on the truck. The MDII came out in 2000, and was replaced by the EZ Plus.

The MDII quickly evolved into the EZ Plus mounting system. It is very similar to the MDII except instead of having three pins on each side, the Yellow handle pins were removed, so the only option is to drop the whole assembly by pulling one Blue handle pin on each side. The other Blue handle pin was replaced by a piece of round solid steel, that fits into a notch in the bottom of the EZ Plus Universal Clevis. This makes it much easier to mount compared to the MDII, because the MDII you have to align the bottom Blue handle pins with the bottom holes in the MDII Universal Clevis. The EZ Plus has a “keyhole” shaped notch, that guides the round steel bar into place. Then it is just a matter of unlocking the Blue handled pins, and pushing up on the Lift Frame, automatically locking it into place.  It was available with the Meyer full trip Moldboard, or the Diamond trip edge Moldboard. Around 2011 Meyer fully absorbed Diamond (which they purchased in 1990) and now offer the Diamond Edge, which is the trip edge Moldboard version of Meyer plows. EZ Plus Mounting Cartons can be used with the MDII Universal Clevis or the EZ Plus Universal Clevis.  Super V Plows and Super V2 plows use the EZ Plus Mounting System as well. This (EZ Plus) is current production.

The Drive Pro came out in 2007. It replaced the EZ Classic TM Series. It is a downsized version of the EZ Plus Mounting System. It utilized the E-58H hydraulic unit up until 2014 when the E-72 became standard. It is available in 6′ and 6′-8″ widths. Originally it was also offered in a 7′-6″ width, replacing the ST, and using the EZ Plus Mounting System, making it technically an EZ Plus Mount plow, not a Drive Pro. In 2014 Meyer renamed the Drive Pro 7′-6″ the “Lot Pro LD”. In 2012 Meyer did come out with a 7′-6″ Moldboard that fits the Drive Pro 6′-8″ A Frame, and they call it the Drive Pro 7′-6″ Single Pull. This is because when the Drive Pro 6′-8″ came out in 2007, it was available for 1/2 ton trucks that could not handle the weight of the EZ Plus plow systems. Obviously the 6′-8″ Moldboards were not wide enough to cover the track width of the Fullsize trucks with the plow at full angle. With the 7′-6″ Moldboard, they are. The Drive Pro utilizes the same commercial grade hydraulic unit, wiring, lights, and controller as the 8′ Lot Pro plows. There is nothing downsized other than the Moldboards.


Remember I mentioned a “few exceptions” above? Well this is one of them. The Xpress Plow came out in 2004. It utilized an E-88 hydraulic unit. It is the ONLY one that used the E-88 hydraulic unit, so if you called and said I have an E-88 plow, I would know exactly what you meant. The E-88 used a wireless controller that was short lived, and with a couple of upgrades covered under warranty, became the E-68. It utilized a Lift Frame that looked like a giant push bar on the front of the vehicle that was NOT removable. The Xpress Plow literally mounted itself on the truck. While the wireless controller was troublesome, once upgraded to the E-68 it was very reliable and very easy to mount. I will even go so far as to say there is no easier mounting plow out there, period. You just had to get close to the plow, and the mount would pull the plow on, self centering itself. Why are the Xpress Plows not that common? They were the most expensive by far. More expensive than any other 8′ or 9′ plow from any manufacturer. Including the more expensive poly plows. The Xpress plow used the Aggressor Moldboard, which evolved with little change into the Lot Pro Moldboard which is the standard Commercial full trip Moldboard sold today with the EZ Plus mount plow system.


There are pictures on our Mount Identification Page to help you figure out what style of Meyer mounting you have.

Lets briefly look at Diamond Plows. Diamond was a trip edge plow company located in Damariscotta, Maine. Meyer purchased Diamond in 1990. In 1991 Diamond plows used the “EZ Pull-Away” mounting system. It was the Diamond version of the EZ Classic designed by Meyer. It too had receiver tubes for the Lift Frame to slide into. Unlike the Meyer EZ Classic, it utilized the H Model of hydraulic units. So while the Lift Frame looked the same as the EZ Classic, the spacing of the bottom crosstube where the pump mounted is lower (2″) to accept the H Model hydraulic units (E-47H, E-57H, E-60H). It also had a Lift Arm to accept two Lift Chains, unlike the EZ Classic single Lift Chain. The Lights, hydraulic units, controllers and wiring were all Meyer, even though the hydraulic units had a Diamond decal on them.


Typical Diamond EZ Pull-Away Mounting

Now you can see why the MDII is called the MDII.
The was the Diamond version of the EZ Classic, the first design shared (essentially) by Meyer and Diamond Plows.
The MDII was the second, hence “Meyer Diamond 2”, or shortened to MDII.
