Hey guys,
I am finally getting back to the 87 Iroc project I started a few years back.
A little history on this car, I bought it in 2009 had an older 305 with a very old gm intake and quadrajet carb. I temporarily replace with an edelbrock intake and carb that has worked great...however the engine that belongs in this car is the 350 with the Tuned port injection.
P.o. Cut just about everything out wire wise in the engine compartment for the TPI. I plan to replace the entire engine compartment wiring along with the crate 350 I just bought and I am now working on new gaskets and porting the TPI.

Where I need help is where the hell do all the sensors go, on the TPI and engine? Cold air sensors, knock sensors, temp sensors etc. does anyone have a picture or diagram to show what goes where? Or what is what on the tuned port intake? Since I am starting from scratch I need a little guidance.

I appreciate the help

If your doing all that why not aftermarket harness and ecm. Holley hp system. Comes with all sensors. I did and very happy with it.

But most sensors are on plenum.
Mat underneath ,tps iac on throttle body, maf on maf, water temp in front, oil pressure in back of driver side runners on block. Knock should be under exhaust manifolds on side of block

I wanted to keep it as stock as I could, aside from porting and a mild cam I didn't want to go to outside the box.
Thanks for the info
