Hi Itchy!
I've a couple more questions that you may be able to answer:
1. After purchasing the Volume + Cursie controls from Honda original parts, how did you connect the wires that came out from the Honda Volume harness to your aftermarket head unit?
There are only 2 connectors I needed to deal with. The first is the connector behind the airbag (post 27 -pic 4 from top) All you do there is plug in your new audio/cruise controls as mentioned in the guide. The 2nd is behind the steering wheel, near the top of the steering column (2nd to last picture on post 27 (wires 3&4)) From there you still need to run 2 wires, like you normally would. Except instead of going to the Honda radio, I went to the Pac Audio SWI-PS adapter. One wire goes to ground (anyone) (black), the other wire goes to the resistance (white) on the SWI-PS. On the other side of the SWI-PS was a plug that fit into my aftermarket Pioneer unit. One item to note is that you'll have to short a couple of wires on the SWI with the supplied diode - otherwise your mode button will not work. I found this out by doing a search here.
a. which model is your Pioneer HU?
AVIC-D3
b. apart from this HU, I think u mentioned that you had another HU as well.. what adapter did you use to connect between the HU and the steering wheel controls e.g. apart from PAC SWI-??
In my Pilot I also have the AVIC-D3, and I also used the SWI-PS. That's it.
c. if you've used and aftermarket adapter (in addition to the Honda Original parts), did you need to tap a +12v ignition to the aftermarket adapter? If yes, where did you tap the +12v from?
Yes, I need to connect the adapter to ignition. I took this feed from behind the radio. I forget which wire it was on our 07, but from a quick search the 06 is purple
2. For the other HU, you mentioned that the Pilot buttons didn't come with a connector harness, so you had to run the wires into the steering reel. Do you mean that you had to run your own wires from the Honda Audio + Cruise controls all the way to the head unit for the Pilot?
As I initially mentioned I only needed to use 2 of Honda's connectors. The first was behind the airbag. The 2nd was behind the steering wheel(top of the column) Fortunately for the civics, the wiring in between these 2 is already run. Not so with the Pilot! I had to run new wiring in between and had to utilize the Honda reel to avoid tangling the wires as I turn the steering wheel.
Thank you in ADVANCE
Glad to help!
Cheers,
