9v power over DIN cable

[Rockers Rollin]

I've got an ongoing project where I'm mounting the guts of 2 BOSS pedals in a 1u rack chassis. Within this chassis I've also mounted a T-Rex Fuel Tanke to supply the power.

The 2 effects will be controlled by a remote foot pedal. Due to the way I now need to wire this remote pedal (related to another post), I need to use a 4 core cable. This then got me thinking, could I use, say a 6 core cable, with 6 pin DIN connectors and also have a BOSS tuner mounted in the remote footswitch.

My question is, could I take a feed from the Fuel Tank and run it via a 6 pin DIN cable, using 2 cores (along with other cores being ground a positive for momentary switching).

Is this safe? Would I need a specific grade cable to handle the 9v?

Should be fine.  Current is more relevant to your application than voltage.  You can see from this snip of DC current ratings by gauge that even 30 gauge is rated for 500 mA, and your DIN cable is probably much larger than that.  You can measure the current draw of your 2 Boss pedals but I'll bet they are well under 100 mA.

You should be ok with 6-pin DIN, but (for example) 5-pin DIN could get confused with MIDI In/Out, which wouldn't be good.

Just make sure you don't have anything else that uses the connector you choose to use. You think you'll never mix them up, but you will eventually, so make it impossible.

Many thanks, so using AWG 24 cable will be well sufficient?

Certainly.
