Hi, guys.

I need help with a new Android head unit. Let me preface this by saying that I'm not an audiophile. I use my stereo to mostly listen to audiobooks and podcasts so I don't really care about excellence in sound quality, amps, bass or loudness. I understand that many among you do and that's OK but I won't spend a great deal of money in that regard.

I just got an Android HU and a back up camera. The physical part of the installation is easy and documented plenty in this forum so let's skip it.

I am overwhelmed though with the wire connections. The unit came with a bunch of harness and, despite searching here, I haven't been able to find the wiring colours for my truck. I don't want to fry anything so let's see if you folks can help me out here.

Here are the stats:

2011 Crew Cab. 130 RES+RSC original radio, steering wheel controls, non-Alpine, don't care for (expired) Sirius. The attached picture is the new HU and the wiring it comes with.

I am very gifted at DIY and such but the last time I dealt with a stereo installation it had a cassette deck. Given my utter ignorance on such complicated units I don't know whether I need an interface box or just need to splice the proper wires and match them to the truck's ones.

1.- All I've read seems to indicate that the Lockpick and similar are for OEM radios. Without an adapter will I lose any chimes or safety alarms or am I overthinking it?

2.- Any of you have the proper wiring colour diagram or has done it him/herself and can give me a hand, please?

3.- I've read that the roof antenna is a dual Sirius/GPS. If true, can it be used instead of the one the HU comes with?

4.- The speaker cables are terminated in RCA connectors but the truck's OEM end up in a multiple socket. How do you deal with that?

I really want to have that camera operative ASAP as I'm parallel parking a 2500 long bed four times a day, often in the dark, and it is not fun. :sad:

Thank you very much for any help you could provide. The forum is a great resource for noobs like me.

Could you post the brand and model of the Android HU? This may help. And I'll start looking.

EDIT: Ok, well, I did a reverse image search and found that the HU is an Eonon GA2114. Here is a diagram that tell what each wire in the back does.



Easiest way to install this is to get one of these:



PAC RP4-CH11 Wiring Interface

The speakers do have an output in RCAs, but they are also in that black box. It is called the ISO Port. You may have to carefully cut the black box off and solder these wires to a new harness. I'm not sure how the stock Reverse camera gets hooked up, but the Wiring Interface may take care of that.

Thank you nemocamaro.

Yes, it's the Eonon GA2114. Sorry about the omission, it was way too late last night when I posted that.

I know the wiring on my HU but I don't know how it matches with the wiring on the truck itself. I was also wondering whether there was a way to avoid buying the PAC or if simply splicing the wires together into the new harness that comes with the stereo would make me lose any functionality.

The PAC instructions for programming the steering wheel controls don't include this brand anyway.

Any ideas on that?

Use this ISO Harness for a plug and play installation.

12-134 ISO Harness

THEN your aftermarket camera RCA should plug into the #24 BACK SIGHT VIDEO INPUT and the camera power can come from a reverse light power wire and tie into the #5 REVERSE CONTROL.

I think though if you want to retain the factory steering wheel controls you will need the PAC RP4-CH11 and the 12-134 ISO harness. If to don't use the steering wheel controls you could just use the 13-134 ISO harness.

The harness on the back of the HU would splice with the harness I mentioned. I see what you are saying about the instructions not including that brand. If this would be a route that you were thinking about taking, I would call PAC and talk to them about your HU. They may have an idea.

As for splicing into your stock harness without buying the PAC, you would automatically lose Retained Power to Accessories. You may also lose audible blind spot detection, (not sure if this feature was on your Ram, or any Ram for that matter.) Though it is possible to get your head unit power and send sound to the speakers that way, nowadays it's not recommended.

I'll see if I can find a stock harness pin-out for your radio.

Your truck has a stock reverse camera, correct? And if so, you are looking to re-use this on your new radio, right?

Thank you larochelle and nemocamaro.

The one thing I don't want to lose is the steering wheel controls. I don't care for voice commands, uConnect or Sirius but I pretty much control the system through the wheel alone.

I do not have blind spot detection and my camera is an aftermarket I just got from eBay, a nice CCD one that I installed in the original tailgate handle and looks absolutely OEM. I just need to wire it once I make sense of the head unit.

I am not afraid of splicing and soldering, i've done my fair share of it, I just know that doing it blindly on the wrong wires may fry the system so I don't want to take risks in that regard.

Unfortunately it seems I'll have to drop $150 on the PAC and some more change on the ISO harness. Wife is going to kill me. :box:

I'll wait a couple of days before ordering to see if anybody can come up with a cheaper solution that doesn't involve making the Crutchfield guys richer at my expense.

Thanks to all of you folks that are helping me out.

iDatalink Maestro

Any of you guys know about the iDatalink Maestro?

On paper it looks better but it is a little bit more expensive and I'm afraid that some of the functionality (like the car info display or the uConnect stuff) is restricted to certain high-end head units.
