Early 90 TB ?

[green97gstspyder]

I found an early 90 TB today in the junkyard but it is the one with only 2 vac ports instead of the one with 4. Can this still be used on a 2g with a 6 bolt swap since I already have the 6 bolt manifold or should I just stick with my 2g one?

I found the how to swap and it says the one I have wont work but I searched and searched and can't find out why. So if someone could shed some light on this for me I'd appreciate it. thanks in advance

The vacuum lines shouldn't be an issue cause you can delete them here's a diagram for that but not sure if you would have an issue with anything else but here's that link

does anyone know how to wire in a 90 tps sensor in a 2g?

 

[Sp1kE]

The 90 is a 3 wire with an external idle switch.
You will need to take that 4th wire from the 2g harness and run it to the external idle switch on the 90TB.

I plan on using link to simulate the idle switch but i dont know which wires to hook to which ones on my 2g harness since they are all different colors. The ones on the tb are all green each with a different color stripe and the ones on my 2g harness are yellow, red, and i forget the other two colors

Vacuum ports can be deleted so that would not be a problem. Same as coolant lines.

Check post #3 and see if it helps you out harness wise.
