Do anyone know of a diagram.of the wiring to go from a runner to a 4.3 conversion. I have got to the point where all.I have to do is wiring the electronics on mine to get it running I am using a 93 4.3 with a 700r4 tranny. Any help is much appreciated.

 

bump, also interested.

 

I pulled the toyota computer completely out of my truck. I have a 4.3 from a 2000 astro and I kept the r150f (toyota trans.) What exactly are you trying to connect between the 2? The toyota just needs the signals for the gauges, and the Engine side should just need Power, Ground, and Ignition. Go to a mechanic and see if they can print you out an accurate copy of your engine wiring schematic. If you don't have much experience with wiring it might be a good idea to order a harness.

 

Buy one of these:

study all the engine control sections, ignition, fuel, etc. The wiring in the chevy already has the engine controls very well separated, just a matter of tracking down the power wires, fuel pump, and some gauges and splicing them into the toyota where necessary.

 

If you should decide to go plug and play wiring harness (v8conversions.com) specializes in Toyota v6 and v8 conversions they got some good stuff

 

ok where do I find the model numbers so I can look them up and get a better idea of what I'm working with?Thank you
