Here's a small twist for you. I have an '89 4runner donor vehicle that I want to use to upgrade my '84 22R xtra cab to EFI. The donor has an auto tranny and I know that the ECU & wiring harness is specific to the A/T (but I believe it has the same plugs on the ECU). Do you think your custom wiring harness would be plug-n-play with this set-up? -- Matt
