Looks like a generic loom for a Link Atom install on a stock JDM RHD AE86 with a COP conversion.

So I will have to dig out the Atom pinout diagram and ...

I have no idea how this custom loom works, so I can only comment in general. There should be one wire from every pin in the ECU plug and you will need to locate the wires for Aux Outputs 1 and 2.

Re: Engine Break In Period + ITB Installation Considerations

If you want your car to start and idle like any modern car you will need an idle-up valve (ISCV). Idle speed control with ignition timing will work fine once the engine is warm or while it is warming up, but it is not enough to get a cold engine started. For that you need extra air and that's the re...

Re: 7k rpms on idle , black top 4age , need help

Pretty much the only thing that can push the idle that high is a decent air leak past the throttles. So if you have checked all the hoses and made sure the ISCV is plumbed up and plugged in, you are only left with the throttles themselves. First thing to check is that the throttle plates are not bei...

Re: Engine Break In Period + ITB Installation Considerations

Yeah, I had a look and those injectors are slightly modified Bosch high resistance
injectors, and they should be good down to very low opening times. Don't lose the
dead time (latency) information supplied with the injectors as that will be needed
when setting up your ECU.

Re: First Start Up Post Engine Rebuild

If you are running on the factory Toyota ECU then it won't want to idle as your modifications have changed some of the basic engine operating conditions.
