I'm thinking defective harness or need a better one. To me scorche are low end and not equipped to deal with the tech in newer trucks.. does the 13 have security that is part of the radio? If so I think u have to have a adapter that can bypass that

What do you mean by security?

 

On some veh the security system is integrated with stereo.

Would you recommend I get a better wiring harness?

 

I just went to their website and for some reason could not find anything for that veh.. Went to Pac site and it looks like their harness is a complete system... compare what u bought with pac

When you say "wiring harness" do you literally mean just a harness? Did it not come with a module as well?

 

no it came with a module, to keep door chimes and such, it was the gm-3000 scorche

 

Try just unplugging and re plugging harness connectors. Maybe one of them didn't seat all the way.

 

Look at the specs between Pac and yours... Pac only covers a few model years per module... yours covers 9 years... your harness/module is missing something for your truck

The adapter he has covers Park Assist. I would try checking the connections on the module and the Park Assist button on the dash.

So what all does park assist do? the scosche just retains chimes. Where pac retains sensors/backup assist

Pac feaatures

Retains OnStar® when the factory radio is replaced

Have a part number for that? And I don't have Bose or Bluetooth factory. Would that make a difference? Only thing my truck has is on star, and the park assist

 

Just go to the pac site and enter your veh info it will pop up.. I personally hate scoshe i put one in my 03 and in a month im now on my second unit and it still has half the issues the old one had.. I may just take the loss and order a pac online and be done with it.

 

Zrock, please do your homework before spouting off that the guy needs a new module. His complaint is about back up assist not functioning correctly. The Schosche module says it retains back up assist, chimes, and other features in the table below. It may not retain as many features as the PAC, but that doesn't mean he needs a new module.

 

I tested it on the way to work this morning. It turned off and came on 5 times in 10 miles, mostly staying off, I'll double check the wiring and connectors after work. But being that it says it retains park assist, maybe this specific one is defective? I could always try another one and if it fixes it then the module itself was bad (or dropped.. it come from Walmart after all lol)

 

Update: pretty sure module is bad, if I turn my turn signal on, aka: get the speaker in the module to turn on, my park assist works for around 15-20 seconds
