hey guys, i just bought a 2000 jeep grand cherokee laredo. i put a double din pioneer head unit in it and im adding a backup camera. i have everything ran but i need to know which wire is the one for the reverse lights?

also whenever i shift into 4x4 and try to go back to 2wd it gets stuck in 4x4... i then have to shift it back into 2wd and slam forward and reverse until it pops back into 2 wheel... really a pain in the neck. transmission fluid is good.

if someone can get back to me and tell me which color wires are for the reverse lights it would be greatly appreciated. also to power the backup camera instead of running the + and - all the way to the front can i tap into the 9v outlet thats back there by the 6 disc changer? or should i just power it with the same reverse light wire that ill be tapping into?

thanks guys.
