Bought a 91 gsx shell with complete wiring harness, I was wondering if anyone knew what plugs do and don't connect to the JDM motor. I know all the EGR stuff isnt there on the JDM motors. As to what else I can leave unplugged I'm not sure. Also, I'm not 100% sure where the main harness is run (i.e. behind intake, in front of intake mani, etc) Any help would be greatly appreciated! - Brett

The issue I'm having is I'm not sure which plugs go where. I have a 91 wiring harness that I am connecting to a JDM 4g63t and the cyclone intake manifold. I need some help with the following plugs. All your help is greatly appreciated.
