    Removing a fisher plow and wiring from a 2002 Sierra and installing on a 2005 Yukon.

    I removed the truck 2 headlight harness from the isolation module, but can find where the headlights harness plugs back into the truck so the truck headlights and turn signals will work again..

    Any tips?

    Thanks Eric

    At the headlights. Well behind them I should say, follow the plow wiring to the front of the truck

    I am not sure what you are talking about. I know where the factory wiring harness is for the headlites on the Sierra.. I am not sure where to plug them back into to make the headlites on the Sierra work again.

    After i remove them from the Isolation module on the fisher wiring harness, the head lites no longer work are as the wiring harness has to be put back to its stock position.

    Look behind your headlights. That's where the plow wiring hooks up. Factory plugs plug into the plow wiring, then the plow wiring plugs into the trucks headlights.
    Again, did you follow the plow wiring down to the truck lights?

    The wires behind that are attached to the headlites went to port 3 and 4 on the isolation module. When I unplugged them they stopped working..

    THere are no addition wires or plugs behind the lights.

    All the plow wires are show below, now i have two plugs on the truck i have no idea where to plug into to get the headlites to work again.

    thanks

    Those 2 plugs plug into the headlights.
    Or should. They should be right by the headlights.

    Wonder if you could help with this issue...

    I installed everything from the 2002 Sierra into the 2005 Yukon... When I hook up the light wiring harnesses and turn the lights on all 4 headlights on the Yukon light up.. Meaning both low beam.. and both High beam at the same time.... It doesn't change when I hit the dimmer switch.

    Kind Regards

    double check your wiring behind your headlights sounds like you have low beam and high beam connectors switched on one side or the other. happen to me before installing a couple plows.

    I checked the plugins behind the headlights.. All are good.. On the short side there are 3 separate wires... Pink.. Purple.. Brown.. Trying to figure where those splice into... On the long side just had a purple to splice..my guess.. Turn signal

    Purple is turn, Brown is parking, and I believe without looking it up, pink is drls.
    Thought you removed it from the other truck, didn't remember the wires?

    If you have the plow headlight plugs orientated the correct way, then your Gunna probably need the drl adapter.
    Look at westerns website and you should be able to find the adapter

    So you have those 3 wires installed or no?
    2 conflicting stories your telling
