I would like to make my own aux input, as I know it can be done for a few $'s in parts, and
I'd rather not spend the money on the MINI kit.

I work for a major connector manufacturer (Tyco Electronics, formerly AMP), and have access samples of anything we make. I've also gotten free samples from Molex in the past.

Does anyone have the mfg/part number of the pins that go into the block connector on the back of the radio?

Thanks,
Jay Snyder
