Josh K. Posted May 28, 2012 Report Share Posted May 28, 2012 Wrong forum to ask. Sounds like you have an auto tranny harness. http://www.plmsdevelopments.com/sr_setup_tips.shtml Quote Link to comment

Josh K. Posted May 28, 2012 Report Share Posted May 28, 2012 Did you look at the link I posted? Pete from PLMS knows his shit. The bigger concern should be what ecu did you get? Best make sure its a manual one. Autos : These use a different TPS. It has 6 wires. Half of it still functions the same as the manual 3 pin TPS - so all of the above still applies (wire colours are different but you still need to measure between the Black and White wires). The other half has switches (for throttle fully closed and fully open) which go to the auto trans to determine shift points. The TPS in auto vehicles is notoriously unreliable. When the auto trans half goes faulty the trans will not shift correctly. Unfortunately the main TPS part also goes bad very quickly. They suffer from moisture ingress. Once this happens a replacement TPS is required. If you've converted to a manual trans then it pays to also convert to a manual TPS for reliability's sake. They bolt up but you'll need to replace the 6 pin TPS connector and replace it with a 3 pin manual TPS connector. You only need the White (signal), Light Green/Black (5V power) and Black (return) wires. Snip the others off. Quote Link to comment

ggzilla Posted May 28, 2012 Report Share Posted May 28, 2012 You can leave it disconnected for now -- it will start and run with the factory ECU. Then later replace the TPS. Quote Link to comment
