I was wondering if antone could give me some pointers on this install.
I have the controller, spec c tank in the trunk, STI auto switch, STI nozzles and a bunch of wire and hose. The auto switch will be used to turn the unit on-off.

I'm curious as to where you tapped for the tps signal and where the controller and temp sensors were placed. Also, if you are using the auto-switch, does the light turn on when the controller is armed?

Any diagrams would be greatly appreciated. Thanks

i can only help you on the TPS signal. check out scoobymods.com
under installing a A/F meter. they have a link to the 02 wrx pinouts for the ECU. :)

Thanks for the lead. That's a big help.

ECU pinouts are always available from the Ravensblade-Impreza (http://www.ravensblade-impreza.com) website.
