This is what I have.
94/95 b18c with the engine harness on it.(Bought from hmotorsonline ) and what we will be doing with this engine is building a turbo motor that will do no more than sit on an engine stand and run. Maybe it will be put into a car eventually. Its a project for work we are doing. So I will be modifying the stock jdm engine harness to plug directly into the AEM EMS. I have a pinout and thats the easy part. What I need to know is which wire is which. Example--- map sensor has 3 wires. Which one is the 5 volt, which one is the signal, which one is the ground? Does the engine harness match the chassis harness as far as color goes or will it be a guessing game? Does chilton, haynes, or helms have this type of indepth stuff. Or would I be best off just getting a junkyard chassis harness and cutting out all the rest of the bs. I have pulled chassis harness' before and it is not fun at all. TIA

 

Anyone??

 

Bump before work.

 

The jdm harness is different from the chassis harness. Just use your stock harness and add the vtec wires, or get a usdm gsr harness. Unless you want to trace each wires and compare it with a usdm harness to understand what they are. So my suggestion is to get a usdm harness and modify it and add what you need to.

 

All I have is the JDM engine harness. I don't want to go to the junk yard and dig out a chassis harness. Thats a pain in the ***. I will probably just end up cutting up some ecu plugs and then doing it myself.
Since thats the only answer I got so far does anyone know of a book that has all the wiring schematics in it? Just so I know which one is which coming out of the sensor. I don't really care about colors. As long as I know which wire does what for that sensor.
