We are almost finished buttoning up the new motor, a TPI 350 in an 86 IROC. There are a few vacuum and electrical connections we can't find. I made a quick page that has pictures of these connections. If anyone knows any of these, let me know. Disregard the last one concerning the distributor, I found that one. If the page doesn't come up, try back later, the host has taken it down (for his gaming purposes).

I have some of these fixed, any pictures or comments wqould be appreciated.

ok lets start off....
1. Looks like it deals with the windsheild washer.
2.There should be a T connection there, and it plugs into the bottom of the Throttle Body
3.That is the EGR, and yes, there is a vacuum line that comes off that and runs to a solenoid in the back that is bolted the the back passenger side of the intake manifold.
4.This plugs into the EGR solenoid.
5.The one you are pointing to goes to the Fuel Pressure Regulater. The other goes to something else, i'll get back to you on that one tomorrow.
6.Looks sort of like what connects to the Fan Switch, but i could be wrong, because the ring terminal i don't know about, i will have to look tomorrow.
7.This too is for the Windshield washer system.
I will get more info for you tomorrow.
I just recently rebuilt an 86 TPI and ran into many of the same things, so I will help you out if you have any more questions, just ask.
I have 2 86 TPI cars at my house right now, one that runs and needs injectors, and one that has the engine pulled waiting for the supercharged 385ci

 

 

Screamer, Thanks. I think I have them all exept for the windshield washer, I'll check on that shortly. What a pain. I do have one more question, I can't seem to find the connector that goes to the coolant sensor that is located in the drivers side cylinder head. It's gotta be there somewhere!

Vader, Thanks for the diagram, wish I'd had that in the first place.
