I ordered an AVIC-D3 from Scionizer07 here on the forums and as part of the deal he did all the wiring for the harnesses for me.

He also wired the SWI-PS steering wheel controller. When it arrived, the only thing that would be required on my part in terms of wiring was to cut and splice 2 wires for the SWI-PS.

Long story short, I followed the directions exactly (its only splicing 2 wires, its not that hard) but the steering wheel controls will not work. I get as far as being able to program the unit to version 8. It won't accept any buttons from the steering wheel when trying to program it.

Also, now that I have cut the 2 wires the from the toyota plug for the steering wheel, my LED's for the steering wheel buttons are no longer coming on.
(I checked last night and it does look like they actually do turn on, but are so faint that they almost can't be seen.)

Anyone have any ideas? Scionizer07 isn't being much help.

 

Can you take some pics of your connections?

 

i had the exact same problem with my install. what worked for me is grounding the ground wire that comes from the pac unit to pin #6 on the steering wheel control harness. my buttons now stay on nice and bright and blue and they respond to the programing.

 

I’ve used both the SWI-X and the SWI-ALP for my Alpine head unit. They both spliced into the TC wiring the exact same way, so I assume the SWI-PS is also the same. Since you are able to program the SWI for program 8, it looks like the PAC module is wired correctly. On the TC harness you need to connect the 6 wire pin to ground. You need to put a 150 ohm resistor (should come with any SWI) onto pin 8. Then wire the end of the resister AND the 7 pin wire from the TC harness to the white wire on the SWI-PS.

 

you also have to have a wire going to a switched lead not a constant lead. i made that mistake and ended up calling the company for help and they told me right off the bat that was my problem. not sure if thats your problem or not though.

 

did the same thing. Took out the ground for the PAC_SWI and wired the AVIC ground directly to pin 6. Solved all my problems.

Thanks guys!
