To help others avoid the pain of trying to figure out how to wire a Greddy boost gauge, I thought I'd share where I found the wires to get it to work.

* Constant Power: Accessory fuse with pigtail, in lower 20 Amp fuse behind compartment on left-hand side of dash

These wires are under the rear console:

* Ignition Power: Red wire

* Lamp Power: Green w/ White stripe wire

* Ground: Black wire

Tips:

* Disconnect the negative battery terminal for the install, you're connecting to constant power

* Check to make sure the gauge powers up and reads 0 turning on the ignition before you button everything up. NOTE: The gauge won't read anything without the sensor plugged in, so you'll need to plug in the sensor to make sure you have the wiring correct
