I own a 2002 wrx that the PO "updated" the interior to a newer sti. The steering wheel is from an 04. The cruise control on the 02 was a push button on the lower dash, on the 04 it's on the steering wheel. So I'm trying to see what I can do to fix it. My question is, does anyone have the service manual for the 04? I have it for the 02 on cd but b/c of the difference it is of little help. I just need the pages on the airbag (I don't want to accidentally set it off), the cruise control, and maybe the horn (I wouldn't mind) it if it worked, it would help me. Thanks a lot!
