This is on an 89' TurboII the harness was originally wired up for a series 4



I have everything squared away I think....but I have a few questions.



There are still 3 leads I have no clue what the **** they do.



1) a green and black, a white and blac Does anyone have any clue where these may go? I think they may be ignition but where do i splice them into?



2) I haven't done anything with ignition, I have no clue how to wire up the ignition, and all I have left are these two leads...



3.) Where how, and do I wire in the knock sensor? If so, what lead is it? I'm out of leads it seems...



4.) I have the wiper rewire figured out. But, is there anything else I need to rewire back into the stock harness? Do I need to redo the tach or anything else? if so how? What about the water sensor underneath the main one in the back of the water pump housing?



5) The switched power lead, where does that splice into?



6) The two 3 prong plugs that come out near the bottom of the harness where it plugs into the ECU, what are those for?



Any help would be greately appreciated. I want to make sure I do everything right the first time, even though I have the deep underlying feeling that something will still go terrible wrong.

1,2. those sound like the ignition trigger wires, the stock ecu wires these thru the ecu conncetor that goes to the dash harness. i like to splice em in, you can too or run the wires all the way to the coils. imo its kind of a waste to run new wires to the coils, because they are already in the car, and be you have to run from the engine to the right side of the car, and that looks funny



3. haltech doesnt use it



4. just the water temp sensor



5. i use the switched power for the stock ecu for that



6. i dunno, pics?

1) where in the dash harness do I splice this into, what are the leads to splice them into?



4) Ok, so the sensor near the oil pedestal is for the water temp gauge in the car..i rewire that into the dash harness. What's the sensor under the main one behind the water pump housing for? Do i need to rewire it in?



5) where is the switched power lead found?

1) fsm!



4) its for the fan in front of the radiator



5) i use the black and white wire, or the black and yellow wire, your voltmeter would be helpful here too

Ok, i think i have ignition figured out.



But, theres a yellow wire in the harness, but i'm not sure what it goes to because its cut. I think it may be the oil pedestal one. Anyone know what color that wire is?
