Hi all,

as per title, I'm chasing an ECU pinout / wiring diagrams / factory service manual for an EJ20R.

ECU is an "87"
Engine is an EJ20R Twin Turbo
Chassis was a manual JDM BD5 RS / BG5 GT-B (either should be fine as they both use the "87" ECU)

Even if it's in Japanese that would be better than nothing :thumbup:

Any chance you have the full JDM electrical diagram service manual (in Japanese) for 97-98 MY?

I have a 96.6 supplement and the ‘95 one coming from Buyee (plan to scan it).

Thanks in advance.
