I talk to a lot of people who want to mod their autos, especially a lot of people who want paddle shifters, so i figured i would post this up so people could find it faster
ok first off i have the roadsurge shift box,
it has a headphone jack out put that is a 3 wire setup super easy to setup shifting. i have an aftermarket steering wheel, that has horn/nitrous buttons that i use for the up and down shifts
the other option that you have is the option to make real paddle shifters, i know its a volvo but its only the paddles were talking
scroll down to the second set of pictures
