I have a Ford 2006 e-250 van, I am having a problem with how to connect relay to dome light wire and door trigger. dome light is positive wire, door trigger is different wire. In manaul it shows how to wire realay with either both positive dome and relay wires or both neg. Also in the manual the schematic for the door trigger shows completely different wiring than that of the dome light diagram. Also there are different door triggers for drivers ,passengers and side and rear. should I just use one (drivers) ? Any help would be appreciated. Thanks.
Also do I need a relay for ignition two. Wiring diagram for my vehicle from (airwolf) design tech shows grey / YELLOW as Ign2 and BLACK/ ltgreen as access, Bulldogs website shows ign2 as BLACK/ green and acc as gray yellow, Directed website shows grey / YELLOW as acces too. Can these wires be both interchangable or is there a problem with the wiring diagram
Also does this unit come form the factory with voltage sensing built in now. manual states connect white wire to 12v constant, only problem is there is no white wire, that pin came empty. So I ran the green tach wire into the engine compartment but havent hooked it up yet. Does anyone no if the white pink wire in the four pin diagnostic is where to connect tach. Also any information on how to test for tach with meter would be appreciated.
thanks in advance
If your meter has a Hz setting on it you can meter out the correct wire by finding one that has AC frequency to it and varies with the motor speed. I was pretty sure on my install that I had the correct wire, but this confirmed it. Hope this info may still help you.
