Nice looking install.

I see this question a lot.
Here's how I did the bypass for the Sony in my 03 Screw. $3 relay.
By using the low amp remote wire to 85, it provides a delayed signal to the relay, causing the HU to be fooled into thinking the parking brake has been applied.
Don't use the remote antenna wire as some HU's don't send power to the antenna unless FM is selected:

I'm going to be installing a PIONEER AVHX5600BHS in my 11 Screw soon. I'll follow the same set up along with a PAC SWI-RC from Amazon for the steering wheel controls.

Won't work on a new Pioneer. They require a double pulse signal. That's why I like my Kenwood...Just ground it.

Thanks Wyo. Just what i needed to hear

Well, bypass isn't working on this pioneer. Any other suggestions on how I can get it to work?

Which one did you use? You need to get one that is double pulse or use the TR7. Pioneers are a PIA to do.

Yea, I figured that out. I bought the $10 one when I needed the $20 one. Luckily MicroBypass is sending me the $20 as a courtesy and a prepaid envelope to send the other back. Phenomenal customer service.

I just fitted a pioneer AVH-x5500bhs. I just used a rocker switch mounted under the 12v aux power out. When the system says to place in park, simply flick the switch on and off and then click ok

I have a pioneer avhx5500bhs. Just fitted a rocker switch. So just have to flick switch on/off and press ok to override.
