: Relocating the PMD

Well, the PMD on my rebuilt 6.5 went after 8K miles. I am going to get the relocating kit. What is the consensus on the best place to re-mount and who to buy from? There are bumper kits, fender wall kits; I am not sure where the best place is to put it. Also. can I leave the old PMD on the pump since it is no good anyway? Anything else I need to know before making the call to order a kit? TIA.

well best place to put it is in the bumper and from what i have found PMDCables has the best prices but if you want the best one heath has the best one but its spendy

Heath is the way to go. 7 year warranty. I've never had another PMD last that long.
No problem leaving the old one in place.

don't mean to hijack his thread, but is it ok to relocate it inside the cab? Mines up under the dash.

Hmm.. I just thought of somethig...could that be the clicking noise i hear?

in the cab it does not get any airflow like it would in the bumper area.
the clicking noise you hear is it when you step on the brake? if so it is the hydrostatic pump unit. if not it is one of the stepper motors in the fresh air control system.

I relocated my PMD to inside the cab also - attached to the side of the 4x4 selector. Reason being, I live in No Dakota and I don't want to have to be fiddling with a PMD (and it would be just my luck) when its -30 and the wind chill is -40. Have found that the heater fan makes an excellent air flow creator. Not sure just how hot the air is coming out of the heater, even at full blast, but I think is less than 100 degrees (moving air after all is cooler than the heater core it travels over). That being so, and the rules of thermodynamics being immutable, that means that even on full blast, the heater air moving across the heat sink will still remove heat from the heatsink. If the heat sink is say (just as an example) 150 degrees from the PMD and the heater air is 100 degrees, then the heat sink will give up 50 degrees of heat to the moving air. These heat numbers are just guesses, but the principle is the same. Even so, do have plans to create a more "refined" looking install in a small metal box with some computer fans.
