wiring 1o1

After over a year, it was time to unpack the wiring.





It was scary. 






Some labels were more legible than others, but even the boost solenoid was still plumbed.




I mean come on, really?!





I separated the bags into several bundles including engine bay, interior ignition, interior body forward and rear. Look! There are the coil pack plugs laid out in the sunshine.




After installing the engine side of the harness, there were 3 grey plugs left, 2 female and 1 male, near the front passenger side of the engine. Usually plugs in the same area are designed not to be able to be plugged into each other. They call it error proofing. Surprising, this wasn't the case. Of the 2 main wire looms running parallel to the engine, each had one of the females plugs, and one also had the male plug. According to my labels, the male and female plugs on the same loom were to be connected. This didn't make sense to me as it would simply create a loop in the wiring, so I plugged the male from one loom onto the female of the other.

It doesn't seem to have affected the engine performance, or running for that matter, but input would be greatly appreciated. I haven't tested it in reverse or even unplugged it since it turned over. Can anyone with an rb25 trace this plug and tell me which side it should be connected to?




From the day's beginning, I was actually impressed being able to wire the entire engine with certainty. Minus one plug with a 5o/5o shot, everything was connected all the way to the firewall including ignition, fuel, timing, maf, alternator, temperatures, idle air controls, throttle body, and grounds.  Even those two funny green plugs that look like they go directly into the block were finally connected. They are the ones you have to insert and rotate, that are next to impossible to get to with the plenum, heater hose, and idle air already routed, and usually involve more than several minutes above and below the car with your hands getting cut by unseen corners and brackets.
