I'm about to reinstall my newly upholstered hinge cover interior panel but before I do I want to mount the dome light to it and wire it in. I have the light fixture but can't seem to find the wiring for it? My guess is that it was cut / removed some time ago.



I know that they don't do much as far as lighting but it bothers me when I see the door switches knowing they don't do anything.



How were these wires run for a 1970 GT? (ie under the headliner? under the car & up the C pillar etc ????)



PS I also have new door switches which will get replaced / rewired too.

Tim, there is a wiring harness that runs up "through" the C pillar and then to the dome light. If my memory services me right, the wires are Purple and a Green/Black wire, so it is a very "skinny" harness and should be covered with black tape. The harness plugs in on the floor back by the right rear taillight. The purple wire goes to the switch for the hatch (If you have one) or directly to the dome light. The other wire is for the rear window defroster.

Perfect!



Thanks Gary. At least I know where to start looking.

On the 70 GT the dome light works off the door switches. The map light on the radio console only works with the map light switch on the radio console. I also have a 70 gt. I don't have a switch on the hatch, do you? I know the hatch was replaced with an earlier model hatch, so mine dome light will only work if one of the front doors is opened. I put 2 little lights on the top of the kick panels that also work off the map light, to give some light in the foot wells.

Hi Ken,



Gary is refering to a third door switch that is mounted up on the right by the hinge. I don't have a mount for said switch but the hatch (probably not correct model year) has a tab that is intended to push it in if it were there.



I did buy three door switches for this project so I may make the missing mount (seems easy enough) and wire it in.

My 70 GT also has the wire running up the c post from the right taillight. There is no hatch switch but the tap is on the door for it and I assumed it was from a later car. I removed the body side of the mount and switch from a 71 parts car but never installed it. The dome light also has a switch to turn it on at the light. I ran an extra wire up to the light for a third brake light that I installed later.
