Haulin_Ls4_GxP Posted May 14, 2010 Report Share Posted May 14, 2010 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. http://chevythunder.com/drive_by_wire.htm 8 pin LS4 06' Grand Prix A TP Sensor 1 Signal B 5 Volt Reference C Common Ground D TP Sensor 2 Signal E TAC Motor Control - 1 F TAC Motor Control - 2 G 5 Volt Reference H Common Ground 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 Quote Link to comment Share on other sites More sharing options...
Guest Removed Posted May 14, 2010 Report Share Posted May 14, 2010 yes the 2 5 volt signal wires matter.. one signal will be 0-5 the other will be 5-0 volts, but both will have a 5 volt coming in Quote Link to comment Share on other sites More sharing options...
