Ok, took a look at the wires on my deck........ Help

Ok I pulled the deck out tonight, trying to get prepared for tomorrow. This is what I saw......

The wires that were probably factory are crimped (I'm guessing. They have a pink plastic piece connecting them) and connected to a wiring harness I believe which plugs directly into the Headunit, I have now. Here's what I know so far

2 white wires labeled as Front L
2 green wires (1 solid one with a black stripe) labeled as Rear L
2 Purple wires (one with black stripe also) labeled as Rear Right
2 Grey wires (1 with black stripe) labeled as Front R
1 red wire with no label but as I could see it was crimped to a factory black wire
1 Yellow which connected to a red and white factory cable
1 black which connected to a brown factory wire
1 blue and white wire which connected to a factory green wire.

And there was the cd changer cable and also a big black cable, I'm guessing the power or ANT??? It had a male connector at the end. So does that sound like a Wiring harness that came with the deck when I had it installed, can I reuse it or what? Will I have to recrimp, let me know, anyone with any experience.
Thanks

red = ignition power - hook to ignition wire for new radio
Black = ground - hook to ground for new radio
Blue = Antenna - hook to new radio antenna wire for antenna up and down
yellow = conatnt +12V with key off for radio memory to new radio's constant power wire.
Speakers. if they are labeled, that should be simple. the black striped ones are the negative speaker connection
White would go to front left on your new unit
Green to real left on new radio
purple to rear right on new radio
Grey to front right on new radio.

Big black end with metal showing and a little pointy nipple about 1/4 to 1/2 inch long at the end is the antenna hookup tot he back of the radio for the antenna signal.

The changer cable is most likely for a changer that if I am reading correctly is not installed anymore... as you never said if you have a changer in the trunk or anywhere under the seats or something.

That should be it, simple enough, the new radio should have pretty much same colors for the main wires, ignition, constant, ground and antenna. Speakers might be different, but new radio should have the wiring diagram for you to follow.

Since there was already an aftermarket deck, your work is easier, because you don't have to figure out the mercedes wire colors for each connection.

Hope that helps.

Scott from SCLJA Willc orrect me if I am wrong, but I am pretty sure I'm correct.

Thanks alot Ashman,
Yea, I do have a cd changer installed in the trunk. My main Question is how am I going to connect the new deck? Do I have to undo the crimping or just plug into a wiring harness or what? That's what I'm not too sure about, Do I just pull the 2 wires apart, what tools will I need?

well by far the cleanest method is to solder and cover in heatshrink.

Otherwise most shops use butt connectors, basicallya cylynder that you crimp the wire in on each end. Usuallyt he blue ones are the right size for it.

As for the changer, if its a kenwood changer, I don't think it will hook intot he pioneer radio. I don't even know if they can convert them.

Ok last Question, so before I can install the Pioneer, I'll need to cut the wires how they are now, to disconnect from the Kenwood wiring harness? can I just cut the plastic piece off and use those cables to connect to the Pioneer? I can probably go to a local store to get crimping materials right or someone else mentioned twisitng the cables and using electrical tape.

Thumbs up right on!

The blue connectors that Ashman talked about are your best bet. (my opinion)

Cylindrical with connections in each end.

Just put a wire in each end and "crimp" them with a pair of standard pliers. No need to buy specific electrical tools.

Worked great when replacing my aftermarket cassette with another aftermarket/different brand single CD player.

Being as anal about things as I am, I still wrapped the connectors with electrical tape.

this you don't want to do, you'd be asking for all sorts of electrical gremlins to show up and once the head unit is in there you won't want to take it out again. worse case you can use twist connectors that gives you a somewhat more stable electrical connection but in cars they tend to work loose and drop off. go to Radio Shack and ask for "butt connectors" or solderless connectors...

That's what's on there now, so I think I will go that route, I can pick these up somewhere like Walmart and just use pliers? That sounds good. Can someone please answer my last question about where to cut the wires? I'll probably first need to strip about have inch of both wires and then twist and then put the connector on and crimp? Sorry about asking so many questions but, when it gets here today, I want to go right into it and install it.

I would cut off the existing connectore that are there and replace them with new ones.

I usually solder my connections and heatshrink them but I like my wiring to be neat and tidy and solid.

I use special crimpers, you can usually find some at places that sell the connectors, which make the job easy. if going with pliers, you might have to squeeze hard to get them to crimp. the ones I use have a curved end and a dimple, and really crimps those suckers on.

The butt connectors are what most shops use, and the blue ones are the right size. The red ones or yellow ones are wrong. Red is smaller than the blue, for very thin cable, and the yellow ones are for thicker cable.

I usually find that for around $5 to $10 you can get a kit with all sorts of solderles connectors and it usually comes with a wire tool that strips, cuts and crimps. My crimper tool cost a bit, but since I used to install stereos when I was 16-18 years old, I still have my pair that I bought off the snap on guy. They were damned expensive off the snap on truck too, but at the time my boss paid for them, and I got to keep them along with a $300 makita drill I still have and use to this day.

I enjoy wiring up stereos as a hobby, and sometimes on weekends I go help my friend at his shop wire up DVD and nav systems and all sorts of crazy things to cars.

Right now he has fully stripped a BMW 740IL and is wiring in a whole new custom System with DVD, Navigation, and the works. the thing is sick.

My friend's tahoe which I have also helped with is the sickest install I have seen in my life, the really sick part is the Alpine F1 Status Radio with processor. The 18" Vega Strokers are also sick. We are still working on it, its been a long process, but its slowly getting there. Should be able to hit at least 170db with that thing if not more. The box for the strokers was designed by cerwin vega as the4y are sponsoring the truck for the woofers.

I myself would never put that much money into a stereo system, but my friend is building it for competition. The alarm for the car does so much stuff, it will be controlled via his cell phone. We are also wiring in a full blown pentium 4 computer system too.

Alon
