LEdcomp, no worries about a partial hijack. Same topic, nearly same platform, and we got Mex contributing to the overall knowledge on the subject, so everybody wins.
When I begin these modifications I will report that 'fool the ecm' resistor value, and I might go with the transpo adjustable regulator on the Mopar casing, and I will solder dedicated ground cable from it to alternator, and perhaps thermal epoxy some an extra heatsink to the casing too.
My desire to have just the remote potentiometer is large though. I wonder what the potting material is and how hard it would be to get through to it and get some wires to it for a remote mount. If i have to i will mount the whole VR unit itself so i can reach the dial on the backside from the driver's seat.
Unnecessary yes, needed no, but I love manual control and 14.9v for hours on end when highway driving on my already full AGM is my main motivator for doing this. The 13.7v when the battery is depleted is quite annoying too.
