22re conversion from 22r '85 4x4 HELP!

[Mark Grant]

Howdy guys, I am jamming the fuel injection 22re engine in my 85 that came with the 22r. I have everything from the donor truck, we are putting a turbo'd LC with stand alone fi in that truck. The guy gave me the old engine and computer, ect. I have searched for a thread here, but haven't been able to find anything. Any help I could get would be great. I have the long block in the truck and am wondering what wires and such I can remove from the truck and how to get the fi and computer in and working like it came that way. Thanks in advance, here is the 300hp 22rte from LC...

when i did mine (no turbo though) i stripped the entire dash, took all the wiring for the 84 out and put the 87 wiring in, there are some computer related wires in the regular wiring harness, i also used the combination gauge from the 87 truck and all related relays and such.

The turbo is for the other 85 I'm building. I am putting a stock 22re in. Any chance of pulling this off without the entire wire harness?

i do not know for sure i do not think you can, up under the dash there is a connector that goes into the regular wiring harness i think it is for your check engine light an gauges,i am not sure what else it does.

I decided to say F the FI. I am going to use the carburetor. Thanks anyway.

It should not be that hard. I just installed a 3FE and it is the same proceedure. You need two harnesses. The engine harness would be used unmolested, two connections to the ecu. The cowl harness would need to be harvested from the correct efi truck, one connection to the ecu. You tease out the efi bits from the cowl harness and use is as a stand alone harness.

It's not that hard.

i did not think it was hard at all, time consuming but not hard, it also helps to have the wiring diagrams in the fsm!
i had to do some additional wiring to make my back window operable since my harness was from a pickup.

That's a "purty" engine you got there.
