well im finally installin my gauges after having them for 5 months. come someone tell me if i need to have a constant 12v power to the gauges or off the 12v ignition. im just wondering cause the book is kinda vauge on what to do. i didnt know if maybe they had some way of storing your setting when the key was off, like flash memory?? oh well i hooked it up accessory, no big deal if i hafta change.

Most just get a fuse tap and work off the interior fuse location on the driver side.Use a test light to determine constant 12v circuit.

Make sure your properly fused.I do believe in the DIY forum there is a post on gauge install.

BMDMAX (Brandon) has a nice right up on a Trippen Mount gauge install in the overhead console.No different just different gauges,Brandon chose Autometer ,same principle.

You want a switched 12v supply for the SPA guage (on/off with ignition)
