Starter relay conundrum

If you have the spade connector on your new relay you could run a wire to the NSS on the automatic trans (middle terminal IIRC) and gain a bit of safety. All it does is make the ground path when in Park and Neutral.

As a kid I jokingly turned the key on my sister's boyfriend's VW Bus. Imagine my surprise when it lurched forward and ALMOST hit a parked car in front of it.
