JDM OBD2 GSR harness in eg
I recently purchased my first Honda after 10 years of building Volvos, so I'm a little out of my element and needed to ask a question.
I just purchased a completely stock 94 eg. I bought a obd 2 jdm gsr with lsd tranny. The harness is uncut and attached to the motor. I have the ecu, mounts, axles, linkage, and info to run the additional wires. But what I cannot find any info on is using the jdm harness in a us-spec car. I can see the engine harness connectors are on opposite sides from what the chassis connectors are. Is there enough slack in the harness to manipulate it to fit? ...or is such a pain that just buying a us-spec harness is the best thing? The jdm harness on the motor is so clean...just seems such a waste to toss it. Anyone have a suggestion? Thanks so much.

You may be able to move some wires, but generally they will get twisted. The ones that don't make it you will have to extend.
Get yourself some decent 3M electrical tape and $15 in split-loom and you can make your 1994 harness look cleaner. You'd have to lengthen many of the JDM wires, so you may as well modify the USDM harness. Cut the pigtails off the JDM harness deep and splice the new connectors onto your old harness. You can also depin the connectors and use the JDM clips in place of the old clips that don't need cutting.
The other option is to get a OBD2 USDM GSR harness. I'd personally go with an OBD1 solution if you plan on doing any mods to the motor.

The tricky part will be the knock and CKP/CYP wires if you keep everything OBD2. The obd2 motor has them on the oil pump, while the obd1 motors have them in the distributor. If you go obd2 spec, you have to make sure you do NOT cut those wires because they are shielded. The shield (aka drain) connects to ground, and a cut/splice is almost impossible to do right.

Yeah, I've had H/F-series on my mind lately. They have 2 sensors on the oil pump for some obd1 and most obd2. The problem remains with a JDM OBD2 ecu is the knock sensor.
