Im getting constant on for my electric brakes..If i do the brake lite switch which is dam near impossible to get to..which wire is the cold side

After replacing the brake switch rubber bushing and it taking 2 hours, I agree with it being impossible, and that was a no-go for me. 

On my 2001, the ACSD (cruise control box) is behind the driver kick plate. In the connector going into it, on the bottom left 2nd to the last position (23) there should be a green/yellow stripe wire that goes to the brake switch.

If your splice were to break the whole wire, it means that the cruise control wouldn't automatically kick off when you press the brake. I never use this method to disconnect the cruise, I always use the button and in an emergency I expect I'd stab the clutch (which would still disconnect the cruise), so it wasn't an issue to me.

If that didn't work, my 2nd plan was to send a wire back in the loom all the way to the actual left rear tail light and connect it to the bulb wire. I already had a wire running up there to tap into the white back up light for the 7 pin.

I don't remember the colors for the brake switch itself if that's what you want to do. I can post up the service manual PDF and send you a link.
