I thought this was a pretty cool idea. They started selling a plug and play harness that reverses the function for the + and - on the automatic shifter. So pulling it towards you upshifts and pushing it forwards downshifts. I guess its suppose to make it feel more like Initial D arcade game or Battle Gear or something. I am sure this can be accomplished by just cutting and swapping the two wires, but this makes it cleaner.

Anyone know what the part numbers are for the two plugs? Maybe we can get a DIY going to make your own.
