Couple connections

Alright. So i'm about done with my 92 Camaro TBI->TPI. This is a 86 305 TPI, so I had to splice to much bullshit >.< anyways. I don't know what these connectors are. or what this plug is. The plug is with all the starter wiring and the connectors are under the distributor.

Re: Couple connections

That bottom one from the top pic looks like an oil pressure sending unit (the larger one). Both look to be coming off the same piping tee, so I imagine the one with two connections is also for oil, though it looks like a temp switch. The bottom pic is too close. Try getting the color of it and where in the wiring loom it comes from.

Are the two in the top pic connected to the trans or the engine block?

Thats helpful. I was thinking oil aswell. They are coming out of the engine block.
I got another one for you. It's right next to the CTS

Re: Couple connections

I don't have the CSI so I had to look this up, but it's the cold start injector switch (thermo/time delay?). https://www.thirdgen.org/forums/tpi/...old-start.html
anyway, there's more info on it in the link just in case.
