Progressive controller on 2005 GTO questions? Wiring in my Nos 15974 progressive controller on my new to me 05 GTO. is there a switched 12v power source I can tap into under the hood? Which wire to tap into on the DBW for the TPS activation? Also which wire is it on the pcm for the tach for RPM activation?

There is many many circuits under hood to use for turn-on signal. Just grab a multi meter & test. You can use a 3m T-tap & a male spade terminal if you don't want to strip & solder. I solder ALL my wiring on ANY of my nitrous installs. My Goat had Issues with BAD wheel hop grabbing 200 out of the gate. When things get shook like that the vibrate & shake loose easily. Anyways the TPS wire you want I Think is dark or light blue. That Also can be verified Easily with a friend or Misses & a muti meter. Just back tap the blue wire with a Thin paper clip & with key on have the pedal position in creased Slowly while you verify with multi meter set on DC Volts that is varies. I Haven't used ANY nos items since the 90's so I Don't know if it will read increasing & decreasing. NX's does. So Make sure it is going in the correct direction it needs to read.
2005-2006 LS2 GTO: tach wire is at PCM, on C1 (Blue Connector) Pin #48 (Brown wire with red stripe). This wire travels from the PCM to the instrument cluster connector (pin #27)

Hope this gets you going!
