I have a USDM 1995 LS (B18b) Auto Integra. I've bought a JDM (B18C) with the Sir-G Automatic transmission. These of course were only sold in Japan. They were never separated and still has all the wiring attached except the wiring harness that plugs into the ecu. I currently have the P75 LS ecu in the car, but I need the JDM P72 for the Vtec to work. The only problem I'm encountering is that the P72 (Auto version) has 4 wiring slots instead of 3... Does anyone know where/how to get the wiring to match there? It seems that either harness will work except the one that goes through the firewall to the ecu... Anyone do this before or know how it's done? Thanks.
