Befor we start, Yes i searched but i found NOTHING. everything is really old and the links dont work anymore.

Alright so i have a chaser/ soarer harness and ecu.

Thanks guys.

Really appreciate it.
BTW a friend I tried to start putting the harness into the car today and it did not work out well.
The harness is out of a chaser and was then used in a 1jz swap into a MA70 so you would think it would be as simple as line up the plugs and connect them, but it ended up being impossible ad we pretty much didnt get anywhere.

What should i do?
There is a good solid thread on supramania that i tried to use but in my case didnt really help out.
This is the thread we used as a reference.

I need to find the EB1 and EB2 plugs in the car.

There are supposed to be located on the drivers side near the junction box #2
Does anyone have a picture of where these plugs would be exactly and what they look like in the car?

Ok first up, its not a simple plug it in and it will work, secondly, chances are alot of the info on the net wont help, as alot of the supras have different plugs and wire colours. I assume you found eb1 and eb2 plugs, if not they are next to/under the fuse box in the engine bay and mine were not shaped like those in the wiring guide on sm, (mine only had 3 wires into em, not the 5 shown etc) however you should be able to distinguish them from the other plugs in the area as they are similar. . . Also I dont see why you need an ecu pinout. . .not needed unless you are rewiring the car completely from bottom to top, plug pinouts are all you need if melding two wiring harnesses together. . . Thirdly, I probably haven't been much help, but heres the best piece of advice I can give you, if you cant work it out, take it to an auto elec and give them the plug pinouts, shouldnt take them more than 2-3hrs to wire it in, money well spent. . . add 2more hours if you want them to really make it tidy with new plugs etc. . .
Heres 2 links I used as a cross checking reference for wires and their purpose, just cause one sheet says connect red to blue, doesnt mean thats right, check and make sure that your connecting speed sensor to speed sensor etc. . . .

dont use the wiring guide on supramania. it leaves a lot out. the soarer plugs go by a different name than eb1 and eb2. If you dont have a cut harness, save yourself the headache and send it out to get swapped.

I'm working on a harness for someone else, it is also a chaser which was used in a supra, now going into a cressy.... it's ALL fucked up. The only chaser wiring diagram is in japanese and doesn't contain nearly enough information. Ugh.
