PAC RP4-CH11 and AVIC-Z140BH Wiring

[Dr Teeth]

I'm attempting to connect a PAC RP4-CH11 to interface between my 2006 300 SRT (Boston Acoustics) and a Pioneer AVIC-Z140BH and I have a few questions. Some of these might be obvious but I haven't wired a stereo to a canbus system before so please bear with me. (At the moment I'm not changing amps or speakers. All of this assumes interfacing with the existing BA system)

1. The pioneer manual specifies that the Avic should be wired to it's own chassis ground. The RP4-CH11 has two ground wires. I'll definitely wire the Pioneer to ground, but should I leave the two grounds on the RP4-CH11 taped off or should I run them to ground too?

2. The AVIC main harness has a blue/white wire. The instructions state "To auto antenna relay control terminal. If the vehicle has a glass antenna, connect to the antenna booster power control terminal (max. 300 mA 12 V DC)". My car's antenna is in the rear window grid, so I assume that's what they mean by a "glass antenna". The RP4-CH11 has a blue wire labelled "Antenna On Input". Do I simply need to splice these two?

3. The RP4-CH11 has a lead labelled "P.B. Output". What the heck is that?

One more question. The RP4-CH11 has a wire labelled Amp Turn On Input. The AVIC has no corresponding output. Is it OK to leave this empty, or should I wire it to accessory power?

OK, I think I have it figured out. Feel free to point out any errors:

PAC: Battery 12V (X2) Yellow to Yellow Always On Power :Pioneer
Left Rear + Green to White Left Front +
Left Rear - Green/Black to White/Black Left Front -
Right Rear + Purple to Gray Right Front +
Right Rear - Purple/Black to Gray/Black Right Front -
Ground (X2) Black to Chassis
Chassis to Black Ground
Accessory Out Red to Red To Electrical Terminal Controlled by Ignition Switch
VSS Out Purple/White to Pink Car Speed Signal Input
Illum Out Orange/White to Orange/White To Lighting Switch Terminal
Reverse Out Green to Purple/White Reverse Gear Signal Input
Amp Turn On Blue/White to Blue/White Auto Antenna Relay Control
PB Output Red/White Unused
Antenna On Blue Unused
Left Front - White/Black Unused
Left Front + White Unused
Right Front - Gray/Black Unused
Right Front + Gray Unused
Unused Green/Black Left Rear -
Unused Green Left Rear +
Unused Purple/Black Right Rear -
Unused Purple Right Rear +
Finally, using the "Bypass" hack/mod, the Pioneer Mute wire (Yellow/Black) is moved to the slot below it's original location, then it and the Parking Brake wire (Pale Green) are both grounded.

I'll hook this up tomorrow and let you know how it pans out.

Tests good so far. Still one or two functions to check, like Bluetooth, but everything so far sounds great and the steering wheel controls work too!

This wire is for any amp that needs to turn on when the radio turns on. Your radio should have a blue/white(should say AMP REMOTE) wire that is for amp turn on as well. Connect amp remote wire (if present) to both wires.

Thanks for that list, planning on an install with those same 2 pieces for my Jeep

i would definitely ground all three wires.

I ended up grounding the deck directly to the car's chassis, and the two wires from the PAC harness too, but using a separate location. It might have worked just fine to put them all on the same screw but I figured that since the Pioneer manual specified that the AVIC be grounded individually I wouldn't risk it.

I left the blue "antenna on input" wire taped off and unused, and connected the Blue/White Amp Turn On wire the Blue/White Auto Antenna Relay Control wire.

The PB wire is the Parking Brake output. As I had done the "bypass" I didn't need that and left it unused and taped off.

All of the above is reflected in the wiring list I posted earlier. I've tested it all now and everything works great! BTW, for anyone wanting to do the bypass this may help: the official Pioneer AVIC Z-140BH BYPASS VIDEO - YouTube

If you grounded your deck to chasis ground then there is no need to ground the PAC wires since they are actually coming from the factory harness.

How is the lag / delay on this PAC unit when sending a signal (volume up and down as an example)? Others have reported a significant delay on other PAC models and I am shopping around for something like this. Thanks!

[robert_ayala]

Anyone?

[ekaz]

Used it on 2 separate installs and zero lag in my case.

[bsuave]

zero lag for me as well!!! used on both my old mag and new charger.5 years running.

[robert_ayala]

Awesome. Thanks for the response.
