Ok so I am using a 2005 Truck tb which is DBW. Here is the link to where I am getting my info. Both the truck and my car use the same 8 pin connector but the wires are in different spots.

E TAC Motor Control - 1

F TAC Motor Control - 2

G 5 Volt Reference

8 pin truck

A TAC Motor Control - 1

B Common Ground

C TAC Motor Control - 2

D Common Ground

E 5 Volt Reference

F TP Sensor 2 Signal

G TP Sensor 1 Signal

H 5 Volt Reference

 

Here is the pin out for my car and the truck tb. So I hooked it up this way and it doesn't work car won't even start. My question is it does it matter where I put the two 5v References or the common grounds? Any help would be sweet. And yes the TB is good I check it on a friends truck. Another thing on that site it say nothing about changing the TAC mod. if your changing the TB only if changing the pedal.

 

This is how I did it and got nothing. When its hooked up and you first turn the key it will open a bit then close and nothing else.

 

A = E

B = C OR H

C = F

D = C OR H

E = G

F = D

G = A

H = B
