1987-1989+ wiring differences ?

[Michael15200]

Can't seem to track down a chassis wiring diagram for my JDM 87 galant vr4, I can only find 1989 and above, just wondering if they kept the wiring the same. I've tried tracing all my wires back and some things are a little different, but the harness has been poorly modified by the previous owner and I'm not sure if the diagram isn't matching due to them changing the harness in the factory or the previous owner has changed it around.

If I'm remembering right they are the same as a 1990 DSM a couple wires on one of the ECU plugs, the CAS, TPS, coilpack, and ISC all are slightly different w/ different plugs.

Yeah that's right, might just see how I go with an 89 diagram
