[QUOTE="machoheadgames, post: 432601, member: 18789"] Also keep in mind a lot of these functions are powered with the ignition key all the time, and they are activated by their ground. I believe the 4x4, check engine light, and parking brake all operate this way. I know for sure 4x4 and parking brake do. So for anything that operated this way, you could just branch a single power to all of them, and then hook up theirs grounds to their respective ground wires. Still not difficult, but that is a need-to-know thing when dealing with the wiring of these vehicle functions. Otherwise if you tie all the grounds together you won't have separate power sources for them and if you made your own power sources, you'd wonder why they all light up constantly. Keep them all powered and control via the grounds and you should have no issues, just like stock. [/QUOTE]
