TBI Harness issues

[ManiacMagoo]

I'm swapping the TBI 350 from my K5 with engine harness and computer into an 88 GMC Suburban that had a 350 TBI. Now where my confusion begins. My K5 has a newer 90 or 91 TBI 350 in it. The engine harness pin out is different from the Suburbans at the bulkhead going to the fuse panel. Now since they are different and the Suburban's fuse panel bulk head is missing a pin that the K5's has does that make this a complete dash harness swap or just a repin of the engine harness? I don't know much about swapping between them. The suburban had a T400 so the harness didn't have the plug for my 700r4 if that matters but was why I switched over.


I got the wiring figured out so this can be deleted.
