I recently swapped a F20B into my sixth gen accord. The car runs, however, when the IACV is plugged in, the car surges. I am getting codes 10 and 14. Since I am running an OBD1 ECU (P28) I went ahead and ordered the intake manifold plenum, along with a 2 pin IACV. I was taking a look at a few wiring diagrams, but I cannot seem to find one that is accurate for my car to match what I have to repin on my ECU in order to run the 2 pin IACV.

Could someone please tell me what I have to repin when switching from a 3 pin to a 2 pin IACV in a sixth gen accord?

 

I'm actually not familiar with the 3-pin iacv however obviously one of the pins is going to be obsolete.

On the 2-pin one goes to the ecu and the other is switched power.

Thanks for the reply. I have been doing some research, looking at pin-outs. It seems as if whatever everyone else is re-pinning on their harnesses/ecus, is already done on mine. For example, Move pin b6 to b23, My harness came like that. I'll assume that no ecu re-pinning is required.

In verification, does anyone know how to change the actual pigtails on the harness from 3 pin to 2 pin? Do I simply use one of the 3 wires as a ground and just use the remaining 2 for the new pigtail?
