2016 PPV Speaker Issues

[TexasPPV]

Hello,

I’m in Texas and I recently purchased a 2016 PPV used by the state troopers.

It’s in great condition overall.

Radio works, but only plays audio to the two rear door speakers. The front door and dash speakers do not work.

I will be putting in a new center console, but want to figure out the speakers first.

Pictures are attached, I already removed the metal police console, there are both in tact wires and multiple cut wires (I assume are police gear wires)

Thank you for the help in advance, I already love this Tahoe!

Welcome to the Forum from NH.

Lots of knowledgeable folks here who freely share their knowledge, experiences, and perspectives. Knowledge is power.

I hope that you will become a participating member in the Forum's discussions.

Pics of the truck, please.

Let's assume that the cluster of wrapped wires contains the front speaker wires. The speaker wires would be the fatter wires, IMO. I would select 2 fat wires, one plain color and one striped color. Get a 9 volt battery and touch the 2 wires to the battery's contacts. If they are speaker wires, you will hear a pop sound from the appropriate front speaker.

I appreciate your response, I took some more photos of the vehicle. I’m going to separate some wires out and start trying the 12 volt.

Also going to be selling the Cop Box in the back, need to find a buyer

Figured out the speakers! All of them work great.

If anyone is having the same problem- it was super simple to figure out.

I looked up the color of the speaker wires, located the harnesses below the dash. It looks like the police installation separated the (factory) harnesses connection, and installed two auxiliary ones once separated with some custom wires. I just unplugged the two and connected the originals.

Look at the picture I attached for visual. The red lines indicate how I received the PPV, and the green line is how I attached the cables that now work. I attached the wire colors I used to locate the wires in the mess as well

Next up:

-get horn working
-get high beams working
-install a center console
-sell the cop box in the trunk
-left door lock/unlock switch does not work
-I want to activate lights when you unlock/lock truck

Welcome from Miami Beach!

Out of curiosity how many miles on your 2016 PPV? Any service records?

173,000 miles! It’s a lot but it drives great for now.

The Texas State Troopers and DPS supposedly (?) Take good care of the vehicles in the department, so I’m hopeful.

I don’t know of any service records, are there ways of getting those? I picked it up from the public surplus store lot.

Mileage sounds okay. I have 150K miles.

I would stop by one their police barracks and ask them if they can help for service records. For the most part State PD's take excellent care of their vehicles. I know the F.H.P. and N.J.S.P. do.

That's really nice locker.

Are you in the Austin area?

Are you in the Austin area?

I am, pretty close to downtown

If anyone can help you with the service records it would be at the DPS ops center at Koenig and Guad.

BTW, i bought thecopcar at the storefront as well at the end of 2018. Then theothertwin at auction at the same place.

I had a delay getting the title for thecopcar, and a nice woman at the ops center helped.

It's pretty cool having titles that show the previous owner as Texas Department of Public Safety.

Thank you for the help! I’ll be sure to ask them for the records.

By the way, how did you end up figuring out the horn/ high beams on the Tahoe? I’ve taken care of pretty much everything else so far.

I didn't have any issues with the high beams. The horn ring hadn't been reconnected on my 2013. It's a light brown single wire down below the radio on that year.

Have you found the GM Upfitter Manual for your year yet? It's helpful with schematics and wire colors/sizes.

If you can find the number use their property ID. It'll be something like C16-xxxx.

Those are some nifty aftermarket buttons on the steering wheel there.

the horn is likely the 6J4 circuit in the center console area upfitter harness. Its a single pair wire that is supposed to loop back on itself. They cut it and run a rocker so they can select either the horn or the HORN (aftermarket). Here's a thread that should be helpful: https://www.tahoeyukonforum.com/threads/15-tahoe-ppv.137696/post-1782543

Thank you SO MUCH. I haven’t checked the form in awhile, saw this and immediately went to work after I got off my job.

Couldn’t find the 6J4 tag but I dug into the pin tail between the seats and lo and behold the two (brown wires with white stripes). Spliced them together, and the horn works.

I can’t thank you enough for pointing me in the right direction.

While I’m writing this, you don’t happen to know anything about the high beams? I can hear the relay click in the hood fuse box, but no dice.

Also, it’s interesting that my horn works on the press and key lock, but the alarm button on the remote doesn’t trigger anything.

Thank you again.

I would guess the high beams were cut for wig wags at the connectors under the hood. That's where I'd start. I'm glad I was able to help you with the horn! With the issues you've had, it would probably be worth pulling off the front bumper cover and removing the headlights. You're probably going to find other extra wires under there you'll want to get rid of anyway. I had to pull mine to get the siren out and it came with about 10 extra pounds of wire and loom, and misc brackets
