Just take the wiring to the LH rear light cluster where by swapping a couple
of single bullet connectors for doubles you can just plug into the existing
wiring (green/purple). An in-line fuse just before connecting to the
original harness would do no harm, but the circuit is fused anyway. I have
no idea what a 2057 bulb but if it consumes as much current as a standard
brake light bulb, i.e. 21W, or more then you may well find it causes
premature failure of your brake light switch. There is a purple (fused,
always hot) supply in the boot/trunk to feed the courtesy light, you can run
that to the additional lamp via the relay contact and use the green/purple
and a ground to operate the relay.
