Code 14 IACV Colors Needed
Hey guys sorry to buy but here I am working on this newly purchased vehicle and everything has so far been a nightmare.
The car idles really messed up, goes really low and then up again. When accelerating barely the car sits at 1500 fluctuating causing the car to bounce and jerk hard.
1994 Acura Integra LS
1997 JDM B18C-R Swap
1996 Engine Harness
I was told that the whole harness from behind the dash was removed from another LS.
So assuming the shock tower harness is a LS.
When I went to see the IACV there was no plug in it. Ah I said easy fix. I said to myself its a Yellow/BLK and a BLK/Blue. I couldnt find any other sensors and finally I found a set of wires cut under the intake manifold, and another set cut by the map sensor. Then I found actual connecter with Yellow/BLK and seems to be Faded(Orange,Pink,RED)/Blue and a Yellow/BLK
What is Red and Yellow/BLK (Found by Map)
Faded(Orange, Pink, Red)/Blue and Yellow Black
BLK/Blue and Yellow/BLK is IACV right?
Okay now I found a plug inside the car its a two pin plug just like IAT, IACV, etc. But its Red and Yellow/BLK. Now considering I only have one check engine light and that is IACV how would I wire the IACV wires to their proper side. Whats positive and whats negative?
My assumption is Yellow/BLK to Yellow/BLK and then Red to Blk/Blue but I dont want to do this and harm anything like the ECU or the IACV. Can anyone help me here thanks again!

Re: Code 14 IACV Colors Needed
Okay so I looked in the car AND WALLA! I found the BLK/Blue and Yellow/BLK Plug. I rewired it to the harness thinking this was the problem! So I just finished, I cleared my codes disconnected the battery a little, placed the key on the "ON" position. Great no CEL. I turned the vehicle on and no CEL but maybe after 20 Second it came back on! The IACV Is BRAND NEW. I had the stock one from the motor, then it was replaced with a BRAND NEW ONE. Not another used one. IM SO LOST I dont know what do. Any help is appriciated thanks guys.
