    I have a 1999 suburban with a MM2 and a 2-wire wiring system, but while plowing the storm last night, the 4WD took a dump on me. I also have a 2007.5 chevy silverado 2500HD Duramax diesel, but when i called the local Fisher dealer for the push plates, they told me that even if i splice the wires into my stock wiring harness in my truck that I would find big problems with the lighting system. Is this true, and Why can't I just splice the plow harness into my factory harness and call it a day??

    Dont do it!!!! Its not that easy any more with these new trucks and it would take all night to try and explain it but the dealer was right. Start messing with the wiring on the new truck and you will have big problems without knowing how the new lighting systems are working.

    Crashed is right So is dealer Dont do it. It all has to do with the new trucks have lamp out sensors. So with the new MA inspection laws you wont be able to get a sticker if you have a lamp out code even if they work fine. They hook up to the ODB port now. Any code now can fail you. But you will have tons of issues if you try it. Buy whatever the Fisher dealer tells you to hook up plow correctly

    seems like it would be a lot simpler to figure out the 4*4 issue than to try and make this work...do you know what's wrong with the four wheel drive yet?
