Just swapped in a D16 with a JRSC into my crx, can't seem to figure out where this plug came from, I'm sure it's right infront of my face and im just not seeing it.

 

did you hava a dpfi in there? if so you dont use it.

 

no, this was stock si, the D16a6 was the orignal motor, this is the orignal harness.

 

Looks like it could be a ect sensor. does it have two prongs? My guess would be that it would go the sensor below the dizzy (ECT). What colors are the wires? It could also be for your fan.

 

looking at the pic again, it may be the IACV. In fact i feel this is more likely. On a stock manifold, it would go into a plug on the back. on a JRSC I think you use one too. Ive got a JSRC sitting in here for a b16 and it appears there is a place for the IACV, so I would assume that you would run one.

 

It's not for the fan, checked that, the plug under the dizzy is already in, this plug branches off of the same wires that go behind the motor for the coolant, oil, and altenator.

 

nevermind, i think it goes in the top of the S-tube.

 

It connects to your manifold. There are like 3 plugs that are there, it looks like one of them...from what I can tell.

 

let us know the color of the two wires

 

if its blk/blu and blk/yel its iacv

 

i figured it out, thanks guys.
