2JZGTE swapped SC3 need help finding home for plug
Hey all I just finished dropping in a Aristo 2jzgte into my 95 sc300 5speed. I have everything hooked up from what I can see but there is 1 plug by the ecu and all the body plugs that need a home or spliced into something. here is a pic of the plug IDK where it came from or is it from the Aristo harness or SC harness. Anyways it has 2 blk/org wires 1 yellow 1 black 1 red/blk wire going to it
Also I have another plug thats on the intake side asyou can see in the pic below if any1 can help identify it? it has a grey wire and a blk/red wire?

thanks for the info so 2 says the white one is not used so it must now be used il go with that. I will get a better pic of the black connector just hanging around the intake side. maybe its used for egr that was on the sc3 setup for some type of solenoid? Its just idles kind of rough and when i gas it, it just dies, Maybe coils or fuel?

thanks all car is running a little better now. I had to re-arrange some wiring on the coil packs, but still missing once i gas it. Still running the SC3 fuel pump, IDK if the usdm 550's, mines ecu and usdm turbos are too much for it?

The 550s and mines ecu are probably killing it. For one thing, a Mines ECU will generally add fuel and timing. Pair that with larger than stock injectors and it is probably just dumping the fuel. Of course the stock SC pump is going to struggle to keep up, so its all really a recipe for disaster without a good pump and some way to monitor fueling. I assume you added a resistor pack with those 550s?

That plug near the ecu in the harness is not used. It is for diagnostics like others have said. Do yourself a favor and put a tt fuel pump in the car before any driving. If you have the aristo ecu, I would put that in and see how it runs. Make sure your main o2 sensor is wired properly as well. If you do not have a wideband on the car, I would strongly consider getting one to see what the car is doing when it is at idle.
