I plagiarized myself from an earlier post:
A convenient place to get unswitched power on a 2000 X is at the power socket relay. This relay is light blue and can be found just above where the parking brake shaft enters the dash. Tap off of the red/white striped wire right at the relay socket. An insulation displacement connector like Radio Shack #64-3052 will work. That red/white wire is fused for 20 amps. The fuse is in the relay box just behind the battery.
