i read on the forum about adding cruise control so i bought the paddle switch and horn wire and installed. It didnt work. After further reading of the rostra instructions (its a 2T1 vin car) i figured i needed the pin40 wire added on so I went to a salvage pick n pull and cut off an ECM connector plug and the plug in the steering column to make a wire with the right connectors. When i went to install the wire i found i already have the black/blue wire in pin40 and my column connector has the yellow wire too, according to rostra info it should already work. Also if i keep pushing the cc's 'on' button it makes my idle get rough for a while too. Anyone else face this? I'm out of ideas now, please help.
