85 tpi harness frustration

Ok im still trying to figure this out but i now know the 85 tpi was an odd year.
The interior harness to the engine harness is slightly different.
Is there and way around not using an 85 engine harness?
I would like to use a newer harness with a serp setup instead.
If i can use a newer harness how can i go about this without swapping out the whole interior harness?

Thanks

You can use ( with work ) the 86 - 89 TPI computer on the 85 wiring harness

The harness has no relationship to the accessory drive being used
