This sticky is great and really caught my attention as a new head unit is high on the upgrade list for me.
I just wanted to add something basic to this post for newbs like me. It's probably common knowledge to some advanced users but I never installed this type of thing so I wasn't well informed on it.
Not having used any PAC products before I thought SWI-"JACK" was their only steering control module or generic term. That's all everyone was talking about here. So I started searching the forums to see if it would work with the Pioneer I was looking at. After some searching here and on Crutchfield I found it's not compatible
. SWI-JACK works for JVC, Alpine, Clarion, Kenwood. What I didn't realize until recently was they make other modules for other stereos lol. Link is here:

SWI-JACK = JVC, Alpine, Clarion, Kenwood Radios
SWI-ECL2 = Eclipse Radios
SWI-PS = Pioneer, Sony (& according to Crutchfield Jenson) Radios
There's a universal and some others there too.

Steering wheel control with Pioneer?
