89 crew cab wiring harness question

I am looking for a wiring harness for an 89-91 Chevy square body crew cab. The harness that goes from the fire wall to the TBI harness and down to the starter. Will an 89' 1500 newer body style work in an older 89 square body style. The bullhead connector at the fie wall looks the same not sure about the wiring difference. Thanks for any help.

Check summit racing. They have most of the harnesses for our trucks.
