Pop the clock housing up and look at the harness going into the clock.

Blue/Red: battery (power when the car is on or off)
Black: Ground (or any point on the chasis)
Yellow/Green: accessory (power when the car is on)
Pink: lighting (power when dash lights are on)


Just a quick look at the wiring manual, it SEEMS but I am not sure, that the wires you are looking at in above the rearview mirror are

Yellow/Red: accessory
Brown/Yellow: Backup light power
Black: ground

What I would do is tap the clock and run some good old 4-wire up through the pillar.

Also, invest in a voltmeter (or better yet a multimeter) and you'll never blow fuses again. Heck you can even get one of those 12v lighting meters. You put the meter to a pin in a harness and then to a chasis point and play around with turning the ignition on and off to see if its BATT, ACC, etc. Saves lotsa time and fuses
