Wiring for fuel pressure

[vypastang]

i got a full electric sweep fuel pressure gauge that needs a 12v ignition source and im not sure which circuit to splice into? any suggestions??

Just find one thats on with the engine and off when the engine is off. Id use a test light and probe the fuses till I found one with a heavier amp fuse. 20 is what I tied into.

Get you one of those "add a fuse" circuit adders from Advanced Auto and put it on any fuse in the fuse box that does not turn on your test light with the key off.:)

Ide wire it into the aux. power for the radio, if your running an after market radio. The circuit is a 20amp i think and I know that aftermarket cd players dont draw that much. If you dont know, the aux. power wire on your radio will be the red wire.

im still using the stock radio so basically thats out of the question but thats the kind of answer i was lookin for thanks

yeah, I'd T-tap the ignition switched 12V+ behind the radio. If they're not choadmonkeys, a local stereo shop might help you with that.
