Pinout ECU Supra MA61

[Commerwel]

Hi There,

I have a Supra 5MGE built in an old motorhome of 1972. I drive it with liwuid gas, but suddenly it won't drive on petrol.

I'am looking for the pinout of the ECU with partnr.89561-14110 or equivalent. It has 2 yellow connectors. One with 9 pins and the other with 13 pins occupied. I've looked everywhere on the Internet and my manuals, but cannot find the exact schematic of it. See attached picture. Is there anyone who can help me out with a schematic of the ECU connetions and a pinout?

Thanks in advance. Roel
