2005 jeep grand cherokee aftermarket radio install

Here is a link to the correct pinout: http://wkjeeps.com/wk_audio_pinouts.htm
If you don't have the factory amp or DVD system then only C1 applies to you.
My guess is that you may have accidentally mis-identified one a pair of wires. Just as a point of reference, if you DO have the boston acoustics system there are only 4 speaker wires (Rear Left and Rear Right).

You should also note that there is no switched power. The way it works from the factory is the canbus tells the radio when to turn on/off. There are "harnesses" that interface with the canbus and give you a switched input wire. This is the route you must go if you have an amp or steering wheel controls. If you don't have either, the alternative is to just piggyback off of the cig lighter for switched power.

Not jiving with the documentation JeepersMisters directed me to.
I have only 10 wires to my harness. According to the link above, using the Radio Connector C1 sheet I was able to ID the wires in my harness. Color codes matched as well.

Pin 1 - Red/Orange - Fused B(+)
Pin 5 - White/Orange - CAN B BUS (+)
Pin 6 - White - CAN B BUS (-)
Pin 11 - Black GROUND
Pin 12 - Red/Orange - Fused B (+) <---Same as Pin 1
Pin 18 - Dark Green / Dark Blue - Right Rear Audio (+)
Pin 19 - Dark Green/Violet - Left Rear Audio (-)
Pin 20 - Gray/Tan Right - Rear Audio (-)
Pin 21 - Gray/Dark Blue - Right Rear Audio (+)
Pin 22 - Black GROUND <---Same as Pin 11

UPDATE

From the above information I have relized I will have to purchase additional hardware to maintain my Boston Acoustics Amp. I'll be swinging by Best Buy after work tomorrow. More $$ to spend but at least I'll still have great sound.

Thanks

If you don't have wiring for the front speakers you probably do have the boston acoustics system. The sure fire way to tell is to check and see if you have a factory amplifier. It is located behind the plastic panel on the left of the cargo area. You may have to pull the plastic out just a bit to be able to see it. It is shown here: http://www.wkjeeps.com/interior_trim.htm#QUARTER

As for wiring a radio with the Boston Acoustics system, there are some things to be aware of. The system is entirely controlled via canbus. What that means is the stock head unit doesn't change volume or fade options. Instead, it sends commands to the amplifier via the canbus to control those functions.(which is why it only has rear L/R outputs and no front ones)

What that means for you is you need a wiring harness that includes a control module to take over these functions. In my installation I used the Pac Audio RP4-CH11. Here is the Amazon link: https://www.amazon.com/PAC-RP4-CH11-Replacement-Mitsubishi-Volkswagen/dp/B0072LCY86

The other option that I believe is a bit nicer is the iDatalink Maestro RR:

Hope that helps!

Thanks ever so much for the links. I did figure it out. Thanks for the links!

No problem! Good luck! Keep us posted on how it goes

Also, just a heads up as to what I meant by saying the Maestro RR is nicer.

The Pac Audio RP4 CH11 functions by telling your amp to turn on and go to its max volume. The volume control is then just left to the output level of the head unit. It gets the job done but there are two downfalls of that method:
1) you no longer have the ability to fade front/rear
2)Since the amp is always at max volume you get a constant hiss/noise from the speakers. It is very, very quiet but noticeable in my opinion. I don't notice it if I have music going. But if I have it paused I can hear it. Not super obnoxious, but noticeable to me personally. (I am also quite picky :grin2

The Maestro RR solves this by interfacing with your radio to give controi over amp volume/fade. These functions do require you to have a more recent model head unit. On their website they have a list of units that work with these functions.

If I were to go back and do it again myself, I'd probably go with Maestro RR instead of the Pac Audio (Wish I had known!). That being said, the shortcomings of the PAC aren't big enough to make me want to go back and rewire now that its done.

Hope this helps you inform your decision of what to use.

Purchased the Kenwood kdc-bt565u
Wanted the hands free BY via Samsung Galaxy S7 (mine) andd Deb's S8
I'm down here in S California (K-Ching). That Amazon link you provided appears to be a Canadian price quote.
I'll see if my KDC is compatible.

That Amazon link you provided appears to be a Canadian price quote.

oh my bad. I was just sending that for reference. I actually got mine at Best buy I think

I'm tempted to say that your unit doesn't support the extra functions of the maestro since it's a single din.

Ordered the unit via Amazon. Will update after install.

Purchased the following;
PAC RP4-CH11
Wired front speaker wires to rear RP4-CH11 speaker wires as/per PAC instructions. Triple checked harness wiring and it looks proper. Connected the radio. Radio powers up but no audio. I do know the RP4-CH11 is communicating with the CAN BUS, I can turn off the key, radio stays on till I open the door.
Ended up swapping the kenwood for a NEW KDC-BT368U but same issue, No Audio. Wonder if the amps is not getting the power on CN BUS signal form the RP4-CH11 ??
Stock radio still functional and powers all 6 speakers.

I did have the original thread below and will update from their ( Audio, CB & Ham Radios, GPS, & Electrical)
So please reply at the thread below
