I tried to install my greddy bcc last night and failed. I know it isn't that hard and I believe my connections were poor, I had too big of butt connectors and that probly was the cause. Where do you guys ground at? Also I hooked my TPS back to the ECU so everything was back to normal so I could get home and start today on it and the car is going crazy....Engine light comes on trac light comes on and it was running rough and it finally stalled and won't start. I did have to put a wire between the TPS wire to connect to the ECU because it was too short. I sorta patched it w/a wire. Can someone help me and do you think that i just have poor connections and im throwing the ecu off?
