Hey everyone i just got my Apexi TT w/ HKS harness, im going to install myself tonight. I have been checking out installing instructions here on i-club & nasioc and seem to be getting conflicted information on how to install so that alarm can be armed while counting down. So here is the issues that need to be cleared up for me.

1. where is the ECU located? (want to tap into o2 sensor wire for A/F function? Is the O2 sensor wire from the ECU white?

2. Do i cut the grey wire going to the alarm module (below console) and tape off both ends?

3. Do i cut the DARK green wire w/ black stripe and tape off bothe ends?

4. Last but not least..... i splice the grey wire to the pink wire coming off the e-brake sensor. (looks like spring push button sensor)

BTW.......I own the 2002 model WRX


Thank you to anyone that helps me out...

 

This is an old thread, but I would like help on tapping wire from the Apexi TT to the ECU. I have an 03 WRX. Please help me out.
