I have changed the factory head unit to a jvc in my 98 GT (standard cd). The JVC has a wired remote input and I'm wanting to add a Pac harness so I can use my steering wheel controls. I have researched and found four possiable harnesses. Not shure which to get so I'm looking for input from you guys. The options I found are; Pac SWI-PS, SWI-Jack, and the SWI-X. Wondering which is my best option. Thanks
