    Make sure it's a 12 pin harness you have before you continue.

    Well........ I have a 9 pin harness to go with my 9 pin plow. What is the difference besides the extra pins. And if so what do I have to do to make the 9 pin work if at all

    Not a good idea to use a 9 pin on a truck that late. So really you have nothing and would need just about everything on both the truck and plow side. Be a good time to update to an Iso system....or a newer plow altogether.

    How bad of an idea. Money is tight and I need to be able to work for this winter. Believe me I would love a new ultramount system but I can't afford it right now since I have to use a 9 pin system what should I do to protect my truck?

    Do you wish to damage the headlamp control system therefore spend hundreds and hundreds of dollars fixing a self induced issue? Because that's the road you'll be on. The 9 pin doesn't keep the left and right headlamp circuits isolated, tie them together and the headlamp control module get very unhappy very quickly.


    $600 would switch all the wiring over to the correct and current system but if that's still too much you can hack it up and trip the relays with a three way toggle. Just do not tie anything headlamp related into the truck except for the battery feed to the relays and a 12V keyed ignition source to the three way toggle.

    Ok now you really got my attention!! So what you are saying is that if I use my 9 pin bad things are gonna happen. Then where do I find the correct harness for both truck and plow side? Well I know where, but where is the cheapest?
