Thanks Stratters, was hoping it would be a chigee or similar, will just have to stop being lazy and put my own cable in.
I'm confused. The connector in the images in OPs first post look like a 2 pin TomTom connector to me. @tater Can you get an image showing the configuration of the three pins. .
sorry, I am the source of the confusion, I mistook the indent for a pin, so it looks like the one in stratters photo and is indeed a TomTom lead.
