    Does anyone know which connectors go into with number with the isolation module? I'm scurrying to get this thing on my Duramax since it is snowing and I need to get it back on ASAP. There are numbers on top of the iso and I don't know which ones to plug into because I don't have the manual. If anyone has the manual I have a 2003 GMC 2500HD Ex cab with a duramax HB3 HB4 lights.

    there should be lables on the plugs, look for them

    3 and 4 are for the lights, i don't think it matters which is which.
    (EDIT) yes it DOES, see my next reply
    I'm trying to figure out if 1 is for plow or control...

    Don't worrie about the correct wiring, go to the hardware store, buy some wire and wire the headlights right to the battery. Deal with the turn signals and correct wiring tomorrow. Go out and make some moneypayup Thats how we do it in Guantanamo Bay Cuba :salute:
