My Gear Vendors Install Thread - '67 Barracuda Notchback 340/416 Stroker
The new units come with a much smaller new controller module which is easier to find a place for. I placed mine inside the driver's side kick panel near the top of it. The first I did was to fab up a mounting bracket for the manual override switch and indicator lights. I'm planning to mount that on the bottom side of my dash just below the ignition key. I also moved the stock dimmer switch upward and inward a couple inches as suggested in their installation notes to allow the Gear Vendors footswitch to be mounted in the original dimmer switch location for ease of use.
I then ran the 4 wires which are in 2 looms through a grommet in the firewall that go to the overdrive unit. 2 are for the speed sensor and 2 are for the activation switch on the overdrive body. I tucked them behind the steel brake lines and then made sure to keep them away from the hot exhaust tubes.
I ran a new power lead from the back side of the fuse block on a circuit that's switched with the key and is also not hot while cranking, as suggested. The ground wire will screw into the body behind the kick panel.
The rest of the remaining wires will be routed over the steering column and attached to the switch panel that I fabbed up. The switch needed a 13/16" hole with a small keyway filed in at the 3 0'clock position and the on-off indicator lights each required a 5/16" hole. They fit nice and snug.
I drilled the mounting holes so that a screwdriver would easily fit between the lights and switch when I go to mount it.
I'll order a second dimmer switch grommet for the carpet and update as I go along.
