My phone kept shutting off due to the cold but I finally got the hand throttle I got off of BadKarma modified the way I wanted it and installed.
Started by cracking the control box open.
Thought I had pics of other parts of this, but the cold didn't play nice.
The way it's made to work is that the power switch and indicator light are on the box with one switch to rev up/down and there's a second remote switch for rev up/down. I wanted the box out of sight under the good, so I pulled out the indicator light and power switch and desoldered them.
Drilled an access hole and ran new wires for the light and switch and ran them into the cab. Going to mount the two switches under the tach with an LED indicator lamp to hopefully match the gauges and rocker switches (I have my switch panel switches planned already and needed the second momentary up/down rev switch anyway). They're small and unobtrusive and they make sense to be right near the tach.
I had to order the LED lamp, so I didn't drill the holes yet.
I also decided to just go ahead and mount the Speedhut dimmer knob and the clock adjustment button under the clock.
I soldered the control wires to the respective IAC wires near the firewall inside the loom so there's no nasty tap connectors. Ran switched power from the distribution center to the control box and got the ground lug soldered on and hooked up. Tested it to the point that I could without firing the engine. Looks promising.
Got a new spot figured out for the Cobra CB and mounted it.
Cleaned up the wiring under the hood, still some wire shortening to do when I get my gauges back and installed.
Getting very very close.
