I've got to go in for some surgery on my arm this week so I spent the last couple of days getting most of the wiring taken care. Knowing that I’ll be taking the truck completely apart at some point I made it so the wiring looms could be unplugged for easy removal and reinstall. Having just 2 plugs to undo to get the gauge cluster out will be especially nice.




I ordered the Compushift mini to control the lockup and overdrive on the 46RH. The electronic speedometer also came in……cause you know what’s a few more wires. rolleyes




Actually the hookup on the Compushift was pretty straight forward. The only minor issue I had was getting the three pin plug that goes into transmission to go in. When I contacted the company I was told the correct plug is no longer available and they supply a GM plug (I did some checking for the correct plug and couldn’t find a source either…… and my buddy at the tranny shop didn’t have one and couldn’t source one for me either). Anyway I finally wiggled it just right and it did go in.

The Compushift also uses a throttle position sensor (in my case cable operated). I was able to find room under the dash to mount that and connect the cable to the gas pedal instead if adding one more thing to the carburetor linkage.

In the back of my mind I figured this one would be pretty simple to wire (and relatively speaking I guess it was). Jut the handful of circuits I needed to run still ending up being a pretty good size pile of wires by the time I got everything pulled into the cab.




The glove box I built turned out to be quite bit shallower that I had planned in order to clear the heater. There was still enough room to mount the ignition control box in it but I elected to mount that on the inside of the firewall up under the dash (it’s still relatively easy to get to). At least getting to the fuses and the control box for the Compushift will be a snap.




I’ve still got to get the fuel pumps mounted (the wiring is already there and switch installed) and hook up the alternator and ignition but that’s pretty much just 4 or 5 wires that are already run.
