Default gc w/ ej207, jdm harness, many questions

The car is a '98 2.5rs with a jdm v5 sti ej207. I picked up the car partially torn apart, but it does run. The previous owner used the jdm harness from the whole car to perform the swap, but I'm confused in the reassembly of everything.

The main problem being so many extra plugs. I think there should be a few left over, but not this many. How can I tell for sure?

The next thing is a check engine light. It originally came on solid. then I plugged the green clips under the dash together and it flashed, 3 long 3 short. Now that I unplugged it, it just keeps flashing at a constant speed. Is this enough info to tell anything?

Also the speedometer and odometer don't work. It's the jdm sti cluster and the rest of it works. I followed the wires and everything seems to be plugged in. Are there any other wires besides the ones that are actually coming out of the cluster that I should check?

Right now I'm using the rhd wiper/signals. This means the turn signal is on the right side of the steering wheel. I have the us one too. I won't plug right in, but I'm sure that it can be rewired. Any suggestions.

Lastly (for now), it has the jdm climate control. This plugs right into the harness, but will it actually work? I think the heater core is the us one.

Thanks guys. I'm a little lost right now I haven't been able to find the answers just by searching.

I was under the impression that the V5 STi wasn't OBD-2 complaint?

Is there a way to check the speed sensor? I'm pretty sure that it's in the wiring though.

If the engine, ecu, harness and every other part are obd1, then does it matter what the chasis is? I don't have to worry about smog.

assuming you used the 98 cluster? on a 98 car the speed sensor connects to the ecu then from the ecu to the cluster ..(i believe) it should be the same for a v.5

so i would check the ecu to speed sensor connection for conectivity

You have a can of worms there, My steering column wire harness plugged into the STi harness. Do you have wiring diagrams?

Good Luck

Thanks for the responses. The cluster is the jdm sti one. I'll check the wires from the ecu to the speed sensor. It plugs into the transmission right? Where at?

I have the wiring diagrams for the US car, but since I'm using the jdm harness I'm assuming there are a lot of differences. Is there somewhere that I can get the jdm one in english or one that's similar.

I did unplug the green plugs. Now it just flashes, but with no pattern.

MY99-01 2.5RS = Version 5/6 cluster is plug and play

MY98 2.5RS = Version 4 cluster, however it is NEVER plug and play.

V5 Cluster in a MY98, not sure what the entire issue is going to be but the wiring is different. For V5/6 the wires plug in the top as do the MY99-01 RS, and V4 plugs into the back, same as a MY98...

That's not really relavent, he's using the complete JDM harness, so his cluster is certainly plug and play.

Do i need the airbag wiring? I don't have a passenger side airbag so I'm pretty sure that the drivers side won't work anyway. Can I just get a steering wheel with no airbag and remove all of the airbag wiring? It's pretty much everything with a yellow plug right?

Oh yeah, the vss isn't even plugged in on my car. The vss is in the tranny, but the plug is just hanging there. How do I find the wires that go from the ecu to the vss?

Yay I found the otherside of the vss plug. No more check engine light. Now if only I could get the rest of the car drivable...

im pretty sure the climate control would work. have you even tried it?

all the extra plugs, just hook up everything that you can figure out. if other plugs are there you will probably figure out what they are for while driving("oh that does that" kinda stuff).

other wise that car is ment to be driven. do it. you dont really need any amenities(ie ac, heater, radio. i know i dont have them in mine)

I haven't tried the climate control yet because I still haven't been able to get the heater core in. I do need heat because I live in Colorado and I'd like to be able to drive it all year.

I've gotten a little more of the wiring figured out. I can buy the piece of the harness that plugs the signal controls into the harness. It's about $60 from the dealership. Does anyone know if I could do something similar with the window and door controls? I was thinking it might be possible to use the USDM in each door and the piece that connects them. I'm just trying to figure out if that piece will plug into the jdm harness.
