    The auto time isn't (from what I have read) a reliable method of monitoring. IE it isn't accurate, I would just get AP, and be done with it,

    Alright so theres the black wire with a white stripe running to the base of the ebrake, thats where I splice the gray wire into correct? I already cut the dark green and black striped wire on the keyless entry module. However, I keep hearing people say to cut a gray wire on the security module under the center console. Where the hell is this?

    Also. Where and how did you guys mount your relay module?

    Okay I have an Apexi turbo timer with the HKS wiring harness. I thought I installed it successfully but it wont even start. I cut the dark green wire with the black stripe from the keyless entry module. I spliced the grey wire from the TT to the parking brake, and grounded the black wire to the frame. That all works, it just doesn't start. If anyone could help me Id seriously appreciate it.

    Note: I diddnt hook up the o2 sensor wires to the ECU, pointless to me.

    Actually, there's only one wire that taps in to the O2 sensor. The other two are ground wires. You can ground them in the same spot.

    Here's where I mounted mine.
