There was a relay and breaker center on many cars with EFI and I figured the 89 might have one. It will give you someplace to connect all the power through other than the old truck fuse panel. A series of relays and a simple power strip can work too.

The frame widths are different on the two trucks so I figured you would have to plumb new fuel lines to and from the TBI unit. You never know maybe the 89 lines will fit right up.

You might be able to use your stock pedal assembly with a new dual output brake switch to control the converter lock up function. It does both the brake light and TCC functions in one switch. They do different things, one is open when the brake is applied and the other is closed when applied. I just don't know if the newer switch will fit the older pedal assembly and brake switch brackets.

The transmission in the 89 depends upon if it was a half ton or a 3/4 ton. It will be a 700R4 / 4L60 if it is a half ton or a T-400 if it is a 3/4 or 1-ton.

I don't know if the wheel bases and engine positions changed between the years so you will have to measure the driveshaft length to make sure.
