Re: C20/cummins 12 valve

Wiring:
Would I need a voltage regulator for a cummins for the swap? Which wires need to be connected to make this work? Should I run the grid heater? Don't get cold in Texas. On the 68 I have the following for the alternator. Red White Blue Black On the starter side I have the following. Purple Black Yellow On the cummins I have the following on the alternator: Big black Green Blue Don't have anything for the starter or the injection pump/shutoff solenoid.

Alternator you can run a Mopar external voltage regulator as a stand alone Setup like the old school applications did, or like mine I used an internal regulator conversion and all I need is one keyed hot wire to the alternator and it puts out 14.4ish at the alternator at idle. Starter solenoid run your original purple wire to it, fuel shut off solenoid on the injection pump just needs a hot in start/run. I have my original ignition source feeding mine as it draws little current. Besides gauges I literally have 3 wires going to my engine.

Starter and fuel shut off solenoid. I used my starter lug as my distribution block for my alternator, battery, and auxiliary take off to feed accessories and the cab, you can see the single purple solenoid wire. Shutoff solenoid is just a female spade terminal. My wiring is a little custom but the engine side will be the same. I planned on grid heaters hence the large gauge auxiliary wire coming off the starter, but in the low 20s mine still hit after just a couple seconds with a fuel heater delete also.

The old school Mopar regulator made my lights “jump” a ford truck regulator will correct this

Did you have a chance to install the mechanical speedometer drive?

Re: C20/cummins 12 valve
The vss screws into the part you bought and isn’t needed. I also bought one but could’ve just removed the vss and been done

Not good.
Attachment 1918872 Figured out why I couldn’t get it running. Hopefully it’s not expensive. “Chrome lever” |

Be warned it is easy to mess up and destroy internal pump parts if you don’t put things back in just right and then you’ll be looking for more parts or another pump. I’ll admit my first time I broke my rotor and since then always know for sure it’s all just right before install. |
