I found connector B in the helm manual. I also found it in my car. I was puzzled that there would be an un-used connector because my car has every option available except a sunroof. Sunroof? Sure enough, the connector "B" in your trunk near the front of the passenger side wheelhouse under the package shelf is your sunroof power connections, for which I would guess you don't have a sunroof. Specifically: The four connectors on top of your diagram are labeled A thru D left to right. E thru H are across the bottom left to right. A is yellow and is accessory voltage. B is Black and is Ground. C is Black (may have appeared brown) and is Sunroof Switch open signal. D is Dark Blue and is Sunroof Switch Low Reference. E is Orange and is Sunroof Switch Open Signal. F-H are not used. I think we nailed it. |

Thank you Mediumfry! I never would have guessed it was for the sun roof. I would have thought that feed would be up the A pillar. Wonder if that means we can use the yellow wire for a remote power hookup. I'm going to have to to find my multimeter and check this out. Is this the manual you can order using the form in the Impala owner's manual? |

I'm sure that's the book that's in the owner's manual. It costs $120 (US). Also, you can get it via the web at www.helminc.com and follow the obvious path to your model/year. If you order through the owner's manual or the web, you get gig'd for about $7.00 S&H. The dealers usually won't order it in for you, they just reference you to a 800 number to call to get it. I don't remember the number or I'd provide that too. There is a TON of information in that book(s). The challenge is to understand how the heck they organized it so you can find what you're looking for. That was a particular challenge a few years ago when I got my first one. However, I've now had one for an '86 Grand Am, '90 Dodge Caravan, and '93 Plymouth Voyager. I'm starting to get the hang of it. Good luck. |

| Ok, let me get this straight... this plug for the cd changer already comes installed if you have the package that includes the amp, am/fm and cd with 8 speakers? Is that why it's not available because it's already there? | |
|

| That's what it looks like. I would think that maybe it was cheaper to make two harnesses, one for the standard setup and one for the premium stereo. If you wanted a CD changer without the premium stereo, you would have to pay the extra $$ for the harness. The strange thing was that I was told by the dealer that a CD changer was not an option if I wanted the CD/tape head unit. | |

I was also led to believe that the CD changer plug was not an option with the "premium" tape/CD radio. I had actually double-checked the sticker and it is not on there so I assumed I didn't have the option. Since I'm not planning on adding a changer I didn't really care, but I have been known to change my mind so I thought it'd be nice to have the option. I guess I do. I wonder why dealers don't seem to know ????? I'm glad I visited and got involved with these bulletin boards. I've helped others learn things and gotten some good from it myself too. Can't beat that. |

Anyone have any clue if the dealer (who installed by aftermarket remote start) can integrate the remote start& alarm with the factory installed alarm (included with the driver info center add on)- not the passlock theft det.? wondering if I can't get them to streamline these key fobs and manually lock my doors without car factory alarm being set off if I use the unlock on the add-on fob (does any of that make sense?) Means I have to use 2 sets of key fobs-( like to let spouse keep the spare.) If I park in the street at home so my kid can pull in the driveway- I do not want to arm the alarm but just manually lock the doors. Crawling underneath to put it into valet mode is a bit impractical. Suggestions for a better plan? |

I ordered my LS with the base radio with the ULO option (it provides wiring harness for CD-changer, amp., and upgraded speakers). I have had a CD-changer in my trunk since May of 2000---it works GREAT!!!!! However, it took me about 3 months to finally get the correct changer parts. Aftermarket changers would not work. Of course I by-passed the amp. |

PLEASE tell us more! What's the model number, how do you control it (i.e. select which disk you want, skip tracks etc.). What "correct changer parts" were so difficult to find? Did the changer simply plug into the harness and work, or did you need to do something to the radio? If I'm correct, the ULO radio is the cassette-only radio. Did you investigate if the UPO radio (CD/Cassette) can control the changer? Do you have steering wheel mounted radio controls? If so, do they control the changer as well? Obviously I'm VERY interested in this since I'll only have a limited amount of time to change my factory order if the changer won't work with the UPO radio. Thanks for your help! Brad |

| Yes, please tell. I have the radio/CD combo, assume the button marked AUX. would run a trunk mounted changer if present. | |
