I have a 91 ls that i am wiring into my 89 hf. what that on top of the back of the intake right under pgm-fi and how do i wire it using my hf harness???? or any other tips would be great.
 
I'm helping rushcrx with this motor swap. I took a pic of the part today and I don't know what it is, more of a domestic mechanic.

All we really need to know is what it is and how do we wire it up to the HF harness.

Mystery Part
 
What, Did honda put this thing on only 1 motor and somehow we ended up with it? C'mon guys, we really need to know what to do with this. It's the only thing holding us back from dropping the motor in.
 
i think you just plug it in.... the HF has one too
 
do you have it plugged into the map sensor? they have similar looking plugs.
 
MAP sensor is 3 prong, comes off the BODY HARNESS - firewall of car
TPS is 3 prong, comes off engine wire harness.
IACV is 2 prong, comes off engine wire harness - branch that goes underneath IM + up to injectors, closer to thermostat housing.

If you still are stuck, I'll try to take pictures of the LS in my CRX for you... 97 B18B in 91 HF
