    I haven't been able to find their run down since they updated their site.

    What you have is a SEHP, and it's setup as a 2 plug relay system. These were started back in 92 if I recall right, and ran until around 2000 (?). Prior to that they had a cable operated EHP, which is very similar to the SEHP. There is a serial number on your plow that will tell you exactly when it was made. Depending on your model plow, you'll find it on the headgear, or the A frame.

    There's no timeline because the systems overlapped. In the 80's they were Speedcast- on truck lift frames with only the blade/ a-frame detaching. There were EHP and under hood hydraulics. Into the 90's they has the MM1 featuring both those systems and the SEHP 2 plug, then in the late 90's the ISO 3 plug system was introduced for those trucks with advanced systems needing isolation between truck wiring and plow wiring.

    Thats when the Insta-Act hydraulics came into play, our 2000 Silverado with a 1999 MM1 had the Insta-Act 3 plug
