In the process of converting my Master Series Broadcast sled to 24v capable.

Have an A/B quick release plate made up, and mounting on the accessory dovetail, no problem.

Figured I'd be running some wires; positive to the positive block, and negative to the pin#3 on the top stage lemo 3-pin camera power. Upon disassembling (most of) the top stage, I noticed an Orange wire already run to pin#3.

Any ideas where this terminates? I've traced most of the wiring back and have only a small and large white/orange stripe wire and a small and a large black wire at the z-section bottom post junction going into the post, and the wiring at the top of the post going to the top stage has a solid red wire going to pin#2 and a black wire going to pin#1, with the solid orange wire going to pin#3. I'm assuming there is a junction/harness somewhere in the post where these distribute?

Was hoping I'd simply find an open ended orange wire and use that... seems it will be more complicated...

Any ideas where to look? Just run a completely new wire up the post and splice in to the existing orange wire? Any experience with this? Is there a better way to go about it?

I appreciate any wisdom available.

Found it!

Harness at the base of the post has an empty pin with orange wire running from it.

finished the wiring based on a schematic which made a/very little sense to me.

Wired as per the simplified schematic below. Am not able to meter 24v between any of the lemo connectors.

Have i wired completely wrong? Is 24v gained through ganging the batteries in series after the lemo connector?
