I would like to operate my z1 with the steering wheel controls. I have the stw-ps ( not sure that's correct), but unless I'm blind, I don't see the aux hole on the back of the z1 that it plugs into! Also, what do I need to bypass my unit? I had instructions on a wire bypass, but my unit doesn't have that connector, I think it was connector 2?? I haven't tried the "flash" method, but from my understanding, it won't work since my truck has daytime running lights. Please help!!!

The 'plug in' for the SWI-PS is in the harness that you are missing. You need to order the harness from Pioneer or eBay. Instructions for the 2 wire bypass are in the hacks group sticky post.

Thanks

Do u know which harness it is?

Wiring harness for RCA Connector 2 is pioneer part # CDE8084.

It's used for the "2 wire bypass", Rear view camera, back seat monitor output, and wired remote input.

parts.pioneerelectronics.com or ebay.

Thanks, I found/ bought it. I also bought some composite a/v cables for my iPhone, they state they're for iphone3, but they should work with the iPhone 4 right?? All apple phones and iPods have the same connection as far as I know.
