I'm thinking about a new pioneer head unit, but I really dont want to lose the steering wheel controls. I know the PAC-SWI interface is available, but everything from the instructions posted on the PAC website to the few installs posted here leave me a little baffled. I'm comfortable enough with doing the install and programming - I've installed many head units and keyless entry units on my own, but I tend to do it the quick and dirty way by cutting and twisting into the wires. Never had a problem with other cars, but this is a lease, so it needs to be clean, reversible and I dont want to take any chances. The PAC instructions were clearly not written with comprehension in mind, and its really not obvious at all which wires need to be tapped into. Can anyone explain really, really clearly what needs to be done? Pictures of the process even better. Also, whats the cleanest and most foolproof way to tap into the wires, preferably without any soldering? Or better yet, is there a harness I can buy for the SWI? I went to best buy and asked them how much it would cost to get a pro to tap into those few wires, told them I'd take it apart, program it, everything else myself. Probably 5-10 minutes of labor at most, and they told me $100. Thats an outrage. If anyone in Long Island, NY wants to help me out on this (AKA youve done it before and wont mess it up), I'll def pay $40 for the time, and Ill bring the car to you.
