Need rear-cabin accessory circuit

[vincedeon]

2023 XLT EcoBoost. In the rear of the cab, I'm trying to find power for a relay, 12V at 100mA at most; I have an auxiliary battery under the rear seat that will power my devices. I can most likely tap from the modem on the rear wall but cannot locate a pinout for the modem nor if it has a 12V ground and a switched lead on it.

Does anyone have a pinout for the modem connector?

The other bits of electrical I see in the rear cab of my truck is the rear sliding window mechanism, and sensors for the rear seat belt.

Alternately I'll just land up tapping fuse 2 (auxiliary) and running wires to the back. I'd rather avoid that run.

Thanks

You can check this out.....

I think I'm interpreting your diagram correctly, that it's hot at all times. I need a pin that is switched on and off with the key.
Also if you have a pinout on that connector handy, that will save me some time.

Most of the truck's modules are always live.

I use fuse 34 on the fuse block behind the passenger kick panel for a switched cct for my dash camera. TCU feed may come alive when you walk by or a different times the truck reports to Ford.

Got it - thanks. I'll run a low current wire from the fuse panel to the rear cabin for this relay.

Thank you all.
