Hey all, I have a 1987 body (which had the diagnostic box next to the under hood fuse box) and I just swapped in a 22re out of a 1985, with the intact wiring harness and ECU. Everything else bolted up and is great, except, that now I don't have the diagnostic box, not do I have the two wire code check port that would have been on the driver's side body in the 1985.

Does anyone have a pinout of the ECU where I could jumper yo get the same effect? Need to set my timing on the new install, but can't do the timing retardation.

Any help is super appreciate
