Just installed greddy turbo timer with harness. Didnt install ebrake or speedo wire but the greddy website says optional. When i turn the key to auxiliary the timer shows "off" really quickly then nothing. When i start the car and try to turn it on it does nothing. The ground is going to sanded bare metal so im ok there, but what am i doing wrong? Should i try a different ground? I harnessed to the correct wires i believe. What would cause this to happen. There is no "If this happens, then" in the greddy manual so im in the dark. Please help.

 

i would just go back and re check everything, did you buy the optional harness for it? or did you splice into the wires of the harness. maybe the turbo timer is fault also!! b/c its a very simple procedure, one ground, and the wires with the harness, which is a simple procedure. but hey, we all make stupid mistakes, i know i do all the time, otherwise i would try to get another one and test that!

Yes, i am using the optional harness, and like u said it is a very easy procedure once u find where to plug the adapter into. Im thinking my ground could be faulty. Im going to recheck it. Thanks for the help CaptanZap.
