Almost ready to fire up the 355 I swapped in! I can't seem to figure out where one wire on the engine harness goes. It is light brown, and appears to go on the driver's side, but am not sure, and has a connector similar to the one that goes to the knock sensor. Anyone know where it goes? Thanks!

 

fan switch?

 

The fan switch is on the passenger side head, but it sounds like it might be a similar sensor. Check the coolant temperature guage sensor inbetween the #1 and #3 cylinders in the drivers side head.

 

No... the coolant temp switch is a green wire that plugs in on the passenger side head! The fan switch has a different connector on it (like a switch connector...duh! ) Hmmm... smog pump stuff maybe? I took all the smog equipment off. I hate to fire it up without this wire connected!

 

did you check a wiring diagram? i would have for you but im at work now.

 

engine harness right? if you can get a pic, i can tell you for sure where it goes.

 

There are 3 coolant sensor on the engine. The one in the drivers side head is for teh guage. The one in the front middle of the manifold is for the ECM. The one in the passenger side head is the coolant fan switch. Trust me, the one in the passenger side head is the fan switch. I've changed it twice, once from stock to a 160*, and then from the 160* to a 195* switch.

 

Oh yeah, that's right. It is in the passenger side head. I don't know what I was thinking. Anyways, I know I've got all the coolant temp sensors/switches hooked up, there's just this one brown wire. What wires go to the tranny? Just the 4-prong plug for the converter lockup right? Maybe this goes there. It seems like a pretty long wire.
