well this part is really overwhelming I'm used to bmws with a nice and simple clean harness this camaro has so much I'm not sure how it was routed I know it goes through the fender and into the cabin but after that where does it go close to the heater box?

anyone have any larger engine bay pictures? where you can see the mainharness layout.

also have three connectors I'm not sure where they go.

this on is near the ground for the back of the block


this one is right next to the heater box


and this one is about 3 feet long

 

number 2 is the power plug for the blower assembly IIRC, just did a non ac swap, got real familiar with that area of the harness lol and that third one i just cut....no harm....yet lol

 

well got one figured out. anyone else know?

 

Nope

Pic #1, tan and blk wires are for the IAT sensor under the TPI plenum. There is a short adapter harness going to a CTS sensor. You would do well to mvoe the IAT to the intake or swap the brass CTS thing for a plastic cage style IAT from a GMC Cyclone. Plastic wont heatsoak as badly as mercury filled brass so the ECM will have a better clue what your actually IAT is and adjust fueling accordingly

Grd ring is right, bolt it to the rear of the drivers cyl head. Any hole will do. Should be another ring or two for the pass cyl head

Tan/blk, wht, blk/red, ppl/wht 4 pin connector goes to the distributor. Theres another short adapter harness than runs from the second dist plug to the coil

Pic #2, fuel pump relay test lead. Add 12v to that terminal and your pump will turn on regardless of what the rest of the car is doing. Nothing connects to it, use for diagnostics only

The tan/blk single pin connector on top of the HVAC box is the DST connector. Unplug this when setting base timing then reconnect

Pic #3, orn, hood light. You can see the inline connector in pic #2 that this goes to
