should be the one in the thermostat housing. That's the one the ecu uses. One in the head is for the gauge and the other is for the fans.

 

I dont think I have one of the plugs on my harness.. i have the one for the thermostat housing, and the single wire one, but not the one that is farthest towards the front... If I'm using neptune and dont need the factory ect gauge would I be fine? I'm assuming neptunes fan controls work off of the one sensor..

 

possibly. i have never used neptune so i cant say. if you have one in the thermostat housing and a one wire in the head then i bet it will work if neptune has fan controls.

nice ***** too

 

a little more progress:



and some yummy.

 

nice nice! some pics dont work and i believe the one wire is for your gauge cluster. if that helps at all..?and one sensor might be for A/C?

 

I have that stuff all fixed

lots of other issues still... and I havent had much time to work on it...
