So i just got 2 22re engines. One is a good long block, one is not running but has the complete EFI system, wiring, and computer.
What are the absolute miniumum required components to run the EFI setup in a '79 truck?
Of course this would be for an offroad, trail only rig, not a pollution controlled on highway vehicle.
I do have access to the complete wiring harness\computer for the '86 EFI system I would use but I want to do a minimal install with only the required components.
I'm not real familiar with the 22RE setup, but so far it looks like I need wiring for the AFM, Distributor, Ignitor\Coil, Injectors, computer, o2 Sensor and throttle body.
And i need vacuum lines for the FPR, Brake booster and ??.
Any one have any pics or links that would help me with the swap?
I dont need evap, egr or any of that junk. Just required components for the EFI to work.
Thanks in Advance!

 

Here is a link to Toyota Factory service manuals. the first one is for 85+ trucks. You should be able to find the wiring diagram that should help part of the install...Good luck.

And you will need the fuel pump too I think. I believe there was a post on 4x4wire in the last 6 months or so where a guy did the swap. Good luck to you.

 

WAY easier to use the harness .. then there is only 7 wires to "splice" 86 EFI , you wont be using the speed sensor .. or probabaly the check engine light .. so maybe 5 wires . you will need the fuel tank and electric pump .. or just an inline electric pump .
