I am installing the controller for my Armytrix exhaust system and the control box can be adjusted to open the exhaust valves up at certain RPM's, but the box needs to receive a signal from the TPS and RPM.
Does anyone have a wiring schematic to show where I can pick this up at?
Ideally I would like to tap a wire/s at the ECM under the firewall, but will go the engine if I have to.
Thanks in advance-
