Alright. I have a Apexi RSM and I am tring to install it. I am having a bit of trouble figuring out what wires do I hook up to the A1 Vehicle Speed Signal. I keep getting a Check Engine light and RPM's won't go past 5000 Revs. I am getting frustrated because I have tried to switch around the Brown wire to the Pink wire to the Purple and I can't seem to finf the right set up. Could someone please explain what I am doing wrong. I have an MY03 WRX Wagon automatic.
