Great information and I look forward to the photos. I am considering a PDM60 power distribution unit, but I am still deciding my path forward.

On the PDM60, I had mixed results (unless they since improved it).

PROS:

Programmable 6 circuits.
One circuit can handle 20A max.
Total of 60A load.
Slimmer profile for mounting.
Overloads reset button cycling unit. No fuses to worry about.

CONS:

Positive wire is a pain to work with. Thick and heavy (due to being for 60A max load) but is not long enough to reach the battery positive or the positive jump terminal without finding and adding extra wire...this was a oversight in design in my opinion because adding length is not something commonly available in most people’s tool kits (who wants to buy a whole spool of heavy gauge wire to add 6-12 inches max?

While programmable, access port is on the back. This improves waterproofing but means you must dismount to reprogram...also means you can’t adapt on the fly to add or modify a circuit in the field. They make a wireless version for more money...otherwise you need to pack the programming cable and a mini laptop on trips...just in case.

Device is USELESS for “always on” circuits. All the LEDs stay lit if any circuit is powered. This will drain down the battery. Likewise, if any circuit has a delayed startup (a touted feature), the unit reboots ALL circuits when it detects the bike powering on...cutting power to the “always on” circuits. If you need uninterrupted power on any circuit, it’s a no go.

All wires are preinstalled. If you don’t use them, you must stow them away because once you cut them, they’re gone.

I ultimately installed a Fuzeblock FZ-1. It’s bigger, only goes 30A max and limits to 10A per circuit, but it is all I need. I suspect that most motorcycles can’t handle 60A of additional drain, so the PDM60 is intended for a broader range of applications. Always on and switched power option based on fuse placement. No drain when off unless a circuit is actively in use. Carrying spare fuses is not an issue if you are like me and always have a bag of tools for emergency field repairs.

Ignore the rat nest...not a lot of space to install things.

I’d normally tuck more of the wire away, but you get the idea.

While I like the plug in connection on the top box, it seems that it would be a bother to a passenger. I appreciate the PDM60 list of pros and cons, that will help me as I move forward on this project.

The plug connection is up to you. Put it wherever it works best for you. You measure twice, cut once. So long as the inside area isn’t reinforced, where the pass-through and bolts need to be, you’re good. It is possible there may be SAE connections with a 90 degree angle to reduce profile.

I don’t worry about passengers.
