There are four wires two black two yellow which ones are power and which ones are ground

SOURCE: no running lights when head lights are on

the brown wire on your suburban will be your park lights and the yellow will be brake/turn are you sure the green wire is ground on your led lights? i would think the black wire would be ground

SOURCE: I have a 1971 with

Last time I looked, black was always the ground... But, been wrong before.I'd check with parts guy to make sure you have the correct motor. If it replaces original design there is usually a sheet with wire re-route diagram. If not, use a volt meter to determine which wires are carrying voltage in the vehicles harness connector. One may have less volts than the other... I would assume the one closest to battery voltage is high speed. one should be ground. If both carry voltage then the case is ground.(usually in this case there is a spade terminal on one of the attachment screws, and a seperate ground wire.) If your new motor has three terminals, it's likely that one is ground, one low speed one high. (though I can't remember ever seeing this arrangement.(speeds usually controlled with resistor block) Again, if this is the only motor available, at worst, I'd tie both power leads from the motor together (making sure that one lead is not a ground) and connect them to the harness spade that carries 12v, make sure there is a good ground, and use as is. But, do some research first.
Good luck

SOURCE: need to know which wire is which out of the map sensor

well if you don't geta answer call auto zone or auto advance

SOURCE: need a stereo wiring diagram for my van.

SOURCE: no power to sunroof?? however fuse is

BLACK MAY BE YOUR GROUND AND THE OTHER WILL BE HOT DEPENDING ON WHAT MOVEMENT YOU ARE DOING ON SWITCH YOU CAN TAKE TEST LIGHT AND SEE WITCH ONE LIGHT UP WHEN YOU PUSH THE SWITCH THAT MAY TELL YOU IF YOU HAVE SWITCH ISUSE OR MOTOR ISUSE TEST LIGHT YOU CAN BUY CHEAP OR IF YOU MAVE TEST METER THIS CAN WORK TO HOPE THIS HELPS
