'85 harness/ecm upgrading to '87

Im going to be switching to the newer '87 harness due to the poor condition of the '85 and i was wondering if anyone else has done this and there is anything besides the ecm, MAF relays, small distributor, and ext coil that i need to change.

thanks dave

yeah but im not repinning'
im replacing the entire harness and ecm because of the condition the stock harness is in and i'm not sure if the firewall bulkhead connectors are the same
i'll just bust out the haynes manual and checkout the differences between 85 and 87 wiring
