Alternatively folks, you get an ISO to a connector with suitably sized pins on the other end in what ever plug suits, use a small paper clip to poke them out of the connector, plug them into the appropriate socket on the car's harness and tape it up tight.

** Check the pins function *thoroughly* before doing pluging anything in and powering up.
** Ensure that no pins are touching each other (use small heatshrink or tape to cover exposed parts.
** Don't try it if you're not confident with the whole idea.
** Don't blame me if you blow fuses, set off air bags or fry the electronic ignition. It's your car, be careful.
