question about 91-94 harness

[undesiredshoe]

I have a 91-94 harness for my sohc to dohc swap. I was looking at the plugs and determining what each one is. I cant seem to find the iacv plugs. Isnt there suppose to be one that is light blue and another one on the intake near the firewall. The engine im swapping in is a de from a 95. Is the iacv on a separate harness??

Yes, the IACV/IAA/EGR temp are all on a separate harness that runs above the plenum.

damn...can i use the sohc harness or wire the sohc plugs onto the dohc harness?

edit...or can i use the 95 harness from the engine im swapping in

The connector on the subharness is the same to the engine harness for all 91-98 models (it's the big 8pin plug in front of the intake manifold, above the upper radiator hose), though the 96-98s have an added portion in the harness for the EVAP volume control solenoid that would need to be removed. The problem is the IACV and FICD plugs are different between S13 and S14, so whichever harness you use you'll also need the corresponding IACV unit.

Funny thing you mentioned it, I just threw away five of those subharnesses last week.

well on my 95 engine, i have the stock iacv and i think i still have the subharness from the 95. Whats devices do the subharness connect too???

Just plug it all in, you're fine.

You can also just take a look at the engine and see it clearly.
