I changed my XLT steering wheel for the leather one with audio. I have a pioneer avic head unit and a swi-ps. I hooked every thing up but when i hook up both wires from the clock spring #2 & #3 for audio and temp to the swi it will not program. If i only connect one wire from the steering wheel i can program those buttons. Any ideas?

 

I did the exact same thing but I originally had the PAC swi-x and was able to use that modification of adding the #2 and #3 wire. I recently swapped out my HU for an AVIC-F900BT and had to change to the swi-PS. The programming of the swi-ps is different and doesn't work the same way. I'm guessing that the Fan and temp controls are putting voltage on the line all the time and it confuses the swi-ps. I'm not that electriconcally savy to figure this out but wanted to let you know you're not alone :o .

 

you need to ground one of the wires.

 

Low thanks for the reply but these were XLT's that we added the Lariat steering wheel to. So pins 2 and 3 were added and then connected to the swi-ps white wire and since there were no pin 18 or pin 19 (?) on the radio harness you can't ground out individually. In theory if I ground one of the wires then that set of buttons (pin 2 temp and fan or pin 3 radio control) wont send signal to the swi-ps. Please correct me if I'm wrong.
