Question on ECM harness
Working on a 1988 RS convertible with 305 TBI and 5 speed. Car was stollen and stripped. They cut the engine harness at the bulkhead on the firewall, as well as cut the ECM harness.
I have found (not yet purchased) an engine harness from a 1989 RS coupe, but it is a 700r4. I found a schematic for the engine harness, looks as only 2 wires need changed.
I don't have an ECM harness drawing, is it easily modified also? Is this do able, or require extensive modification? I don't wish to purchase the 1989 ECM harness, only to find it's more trouble than worth for the 1988 with 5 speed
Anyone have a link to 1988 and 1989 ECM pinouts?
Thanks so much for responding.

Shouldn't need to change anything.
The P/N input is not used on a stick car
The 5spd prom won't be using any of the wiring going to the auto
