hgray14 Posted December 29, 2008 Report Share Posted December 29, 2008 My car stereo stays on even when the key is out of the ignition.I just installed a new Pioneer DEH-P7900BT stereo into my 1993 850 GLT. I already have the same stereo in my 1995 850 Turbo and it works fine. I used the BHA-9920 wiring harness adapter, which appears to be the exact same one as in my 1995. Once everything was spliced in and hooked up I plugged in the stereo and it works fine except that it stays on even when the key is out of the ignition. That doesn't happen with my 1995 even though it is the same exact stereo and appears to be the same exact wiring harness adapter.Any ideas?The only connection that I made that was different was the blue wire which has a tab which says something like "remote control"...or something like that. It came with a flat connector and since I didn't have the male end to fit it I just spliced the wire directly. I thought that might be it but when I unplug that same wire in my 1995 all it does is stop the antenna from going up...so it is the antenna remore power control. On the 1993 I even cut that wire just to see if that might allow the stereo to turn off when the key was off but that didn't make a difference.help me please...this is my girlfriend's car and I hate the idea of her having to remove the faceplate in order to turn the stereo off or else risk running her battery dead.thanks in advance.Houston Link to comment Share on other sites More sharing options...
BEJinFBK Posted December 30, 2008 Report Share Posted December 30, 2008 If you used a wiring adapter, all the colors should match right up:12V Ignition / Acc. . . Red 12V Batt / Memory. . Yellow Ground. . . . . . . . . . . Black Power Antenna. . . . . Blue Amp Turn-On . . . . . . Blue / White Amp Ground. . . . . . . Black / White Illumination. . . . . . . . Orange Dimmer . . . . . . . . . . Orange / White Right Front (+) . . . . . Gray Right Front (-). . . . . . Gray / Black Left Front (+) . . . . . . White Left Front (-). . . . . . . White / Black Right Rear (+). . . . . . Violet Right Rear (-) . . . . . . Violet / Black Left Rear (+). . . . . . . Green Left Rear (-) . . . . . . . Green / Black The good ones even print the function right on the wire! That is so cool... You DID use a wiring adapter, right? Link to comment Share on other sites More sharing options...

You DID use a wiring adapter, right?Yes, I used a wiring adapter...and all the colours matched up...and I even had my identical stereo and wiring adapter from another car to compare it to so I am not sure what is wrong.

BEJinFBK Posted December 31, 2008 Report Share Posted December 31, 2008 Well, it sounds a lot like your switched power has some how become constant.Just for grins, does the clock keep time? Does it remember station presets?Just a thought...Otherwise, time to get a DMM and a wiring diagram out and get to it. Link to comment Share on other sites More sharing options...
hgray14 Posted January 1, 2009 Author Report Share Posted January 1, 2009 Well, it sounds a lot like your switched power has some how become constant.Just for grins, does the clock keep time? Does it remember station presets?Just a thought...Otherwise, time to get a DMM and a wiring diagram out and get to it.I will double check on the clock and the station presets. Since I am having my girlfriend take the face plate off every time she turns the car off, in order to keep it from draining the battery, it will be interesting if it is keeping its memory. I am guessing if it isn't, that means two of the wires are crossed...although all the colours match up. Since I bought the harness cheap on ebay it is possible they messed up the connections. I should double check to see that the location of each coloured wired within the harness is identical to my other one. If it isn't that could be the problem. - I hadn't thought of that one.thanks for the suggestionsHouston Link to comment Share on other sites More sharing options...
Chilled man Posted January 1, 2009 Report Share Posted January 1, 2009 sounds like red and yellow are backwards Link to comment Share on other sites More sharing options...
MyCarIsRed Posted January 1, 2009 Report Share Posted January 1, 2009 sounds like red and yellow are backwardsMy car had 2 power lines and one acc (2 red, one yellow). Check if maybe the harness is sending the acc wire from your HU to one of those 2. If you truely swapped all the reds/yellow then the HU should not turn on. the acc wire (at least in my pioneer) is more like a switch and can't power the unit.

MyCarIsRed Posted January 1, 2009 Report Share Posted January 1, 2009 which Pioneer do you have?currently just the 3100ib. Havent had this one apart, but i had to do some surgery on an older one (2900) couple years back. I spliced mine directly tho, was too lazy to go back to the store for a harness.
