I ended up selling my ignition light as when i came to fit it on the sr there's a ignition chip that recognises the key and that stopped me fitting it, there were a few ways around it but would have been a huge pain in the ass! as the chip was in the actually barrel surround and it plugged into it not sure if all are like this or not! could have cut the chip out and cable tied it to the barrel and so forth but yeah..,. wiring is easy you need to send the red wire to a live and the black to an earthing point and as for the red wire with silver stripe in it you need to wire that upto either the interior light on door mode or wire it to the switch that is in the door sill that activates when the door is open! ! Also i noticed when getting mine to power up that you have to make sure that which ever way you use as a switch make sure that is earthed also as on the light only the bulb holder is earthed by the black wire so make sure the switch mechanism is earthed! this is how I got mine to work have pictures to prove
