22604 E58H E61H Meyer Diamond 1 Piece Plug Plow Side MDII/ Plus Mount Plow Harness

Here is the Meyer Harness 22604. This is the plow side plug that was used on the MDII and Plus mount plows. This is used for the E58 and E61 pumps only because it has the weather proof plugs on the end.  It is a quick-disconnect 1 piece plug. This plugs into two drifferent truck harnesses - 22610 and 22261. This one is most commonly used with the 22610.

There is also a later round version. Make sure yours is shaped like this. This is a 17-pin harness. It has the power and ground, but you also need the truck side cables for it to plug into. It has the Nite Saber plugs and the 3 pump solenoid wires. Make sure you get a tube of dielectric grease to protect these plugs.
