Seeing the the old thread in the how to section is a little old and outdated I just wanted to start a thread to shed a little light on the topic since I have been having some trouble installing mine. I installed the harness for the apexi tt into the ignition harness and have all that setup since there is no power harness. I have three other wires that come from the harness, a black, grey, and white one. The black one I am aware needs to be grounded to the car, the grey one and white one are for the ebrake and o2 respectively. The problem is, when I think I've grounded the black one, i turn the car on and there is no power to the timer. I pulled out my ecu and was going to put it in either pin 13/26 yet both were taken up (must of been from another install) and the o2 sensor one was taken up aswell (i dont know if i'm suppose to remove the stock one and put the new one in there or what). Any help with what is the best place to ground the black wire and if I'm perhaps missing something, please let me know. All i've done so far was good the harness up to each side of the ignition and concealed all that, now I just have these wires to work with. The How-To thread about this I read up on and still could use some help.

Thanks.
