The rule of thumb on a GT from my experience is:
Brown wires are grounds
Gray wires are interior lighting circuits
Black wires (with stripes) are switched positive
Red wires are battery positive
Blue wires are usually gauge sender related.
I’d wire it to one of the 4 studs in the middle of the fuse box with an inline fuse added. From memory, when upside down under the fuse box there is a red and white striped wire just to the left of the center of the fuse box (going onto the passenger side stud closest to the nose of the car.) that is your direct battery + into the car. Add the wire onto that with probably a 5 amp fuse. Or whatever your radio recommends.
Please review your wiring diagram to check my memory though.
MODERATOR'S NOTE: Thread moved to the "Sound System" Forum
I would suggest the clock wire, as it is "hot" all the time, and should be fused sufficiently to provide memory retention for a radio. I don't have a wiring diagram handy (it's our final week of our month in Maui) but IIRC, it is an 18 gauge red wire.
Hello all I'm finally getting some down time a/c season for me gets me super busy
My son and I started on the sound system in the gt a couple few months back as were on too the redo of some of the interior.
although we have an extra gauge cluster panel/dash we really didn't want to cut either of...
The car I’m picking up next month looks like it needs a new antenna. 1972 gt. The one on it looks to be taped. It doesn’t retract. Anybody know where to find something similar that would just bolt on? Thanks
O.K. audiofiles, here is a question for you. I have four 6.5" 2-way Pioneer speakers in my GT. Two are mounted in the footwell and two in the rear side panels. They are all protected with speaker baffles. XTC 6-1/2" Speaker Baffles (3-1/4" depth) Protect your speakers at Crutchfield.com Also...
