Power and ground question.

I have an 05, and when I wire in the power or ground for my gauges and shift light, the car will not start. Almost as if its triggering the security system. Anyone else deal with this problem?

need more details.
Where are you wiring the gauges?
What gauges?
Are you wiring ground or perhaps the feedline?

Sorry, should have been more specific. I'm grounding at the drivers driver's side floor board, at a factory ground location using a factory bolt. Power for the gauge lights is being pulled from the headlight switch, and the gauges are a mechanical boost gauge, and an afr innovate gauge. The raptor shift light is grounded at the same place, but pulls signal from a cop signal wire. Power for it is in the fuse box, can't remember which circuit.

You can not take Power from the headlight switch, it is just an "grounding" switch that Controls the behavor of the SJB (lights on or off)

It works for illumination, which is all I'm pulling from it. But that must be why its triggering security when I try to start it? Where do you pull light signal from?

you are back feeding the sjb....

You can't use ANY wiring from SJB they are all ground control activate hot all the time.

You gotta run power from the sjb via a fuse tap into the power required devices
For signal, i think you need a tac adaptor?

I had my autometer gauges with LED bulbs tied to the dimmer circuit in my 08 at the switch with no issues. Are you using old school incandescent bulbs?

One gauge is led bulb, the other is an innovate afr digital gauge.
