View Full Version : Accurate wiring diagram (starting, ignition) for JDM ST185

Anyone know where I can find this? Specifically for Starting and Ignition? The Ctech BGB is USDM. Everything you find online you don't get the subtle differences. I need a 100% accurate diagram to trouble shoot a really annoying problem. Thanks,

I would start with the BGB. My car has a JDM engine in it but used the stock wiring harness. The only thing on the harness that didn't get hooked up was the EGR components. This is due to the fact that the JDM engine doesn't have the EGR system.

It may not be perfect but is should be close enough. It's going to be very difficult to find a Japan diagram, much less one with English on it.
