2022 Yukon SLT Power plug on passenger door well

Do you know the size of that wire, it should be 10 gauge wire to handle 30 amps. The intended load of that wire might have been very low, you could melt that wire and others in that harness before a 30 amp fuse would blow. I'd run a dedicated 10 gauge power and ground to power that CB.

The wire is 16mm2 or around a #4 - 6 AWG. Should carry 30A with very little voltage drop. Make sure you install an adequate ground.

Looking at using this connection for a small Amp instead of pushing through Firewall. Did you ever figure it out at the battery!
