For the trans plugs though?? What will I have to do to have my trans and the jzx90 auto ecu hooked up.
It looks like the plugs are different. Will i have to remove the wires and plugs from the za70 and tap into the zx90 harness or ecu??

Thanks

Yeah you are going to have repin/replace plugs . You are working with a a70 motor an x90 harness and an XX truck. It is a safe bet that nothing is going to match up. You are going to have to rely on function rather then color or plug to determine what wires to what.

Honestly I would just go to a junk yard and find male and female plugs that have the correct number of wires and start swapping.

If you don't go custom harness from someone like Dr. Tweak, you would be better off getting a complete harness/ECU that isn't chopped up.

Yeah and spend a thousand bucks on something you can do your self.

My opinion is if you can't figure out the wiring then you shouldn't be doing the swap.

Op, this is what I had to do ImageUploadedByTapatalk1364566825.177629.jpg
When I had to connect something that didn't match. I used the different wiring diagrams to figure out what color wires came from what sensor and what the corresponding wires on the harness were that match their function. The plugs are just that... Plugs they just connect... The color of the wire is just the color . What matters the signal get the signal from the source to the ecu and you are cooking with peanut oil.
