Hey guys I have my 98 prelude with my euro-r in it. I have a two wire iacv with Rosko's racing iacv adapter plate. I do want to run the oem PCD or euro-r ecu in my car plus I am also buying the jumper harness that goes from obd2a to obd2b for the ecu to plug in properly.

I am asking how can I use or wire up my three wire iacv that came with the engine swap? I would like to use that one instead of the two wire USDM h22 iacv, since the new ecu will want to read the 3 wire control valve. Please help if you have any insight on this issue. thanks

Look up the ecu pinouts for the Euro R and hardwire it to the ecu. Use a connector incase you need to pull the engine, you wont have to cut the wires

why change anything, just use the block off the euro-r and keep everything the same

I am not going to change anything on my setup I just ended up buying an obd1 ecu chipped with a dyno-tuned euro-r map on it. So I wont have to change up anything and I can still use my old usdm ecu to pass smog when I need to in two more years.
