Pre-89 SAFC Wiring Install

[enjoi.this]

Ive been looking around everywhere and cant find the wiring pin out at the ECU for a pre-89 yellow plug harness to wire in a SAFC II.

Did find a write up for an 89+ grey plug but thats it so far.

If someone could enlighten me on the RPM, Throttle position, Air flow signal, and knock wires at the ECU, I would really apprieciate it! Suck's having a car apart and not being able to finish it up.

Found some of the answers to my question after trying different word combos on google

87-88 ecu pin out

Now the only Wire that im not sure of still is the RPM signal which isnt in this pinout? It's said to be the green wire on an 89+ but i doubt it is the same on pre-89.
