I just got an older iPod and put Rockbox on it. Rockbox supports a car mode where it will start and stop based on power, so I would like to have the lighter socket turn off at the same time the radio does - e.g. when you open the door. Instead, it of course has a delay (5 minutes, I think?). I was wondering if this is something that can be configured with a Tech2, or if I would have to tear into it and rewire it to get power from the radio circuit?

WOT ... is there any other way?

Not aware of any plug and play options. My suggestion would be to get an extension cable ...  (Make sure you get one without a pilot light that could still draw power when you shut the car down!) And a relay w/connector ... basic instructions should come with the relay, available from any auto parts.  Split the hot lead on the extension cable and wire the relay into that, then tap the relay into an accessory position that turns off when you shut the car down. Never tried it myself, but I'm sure there's something handy in the center console area that would work. No added load to whatever ACC circuit you use, as that only acts as a trigger for the main power that would be supplied by the lighter. PS ... probably not a bad idea to fuse the relay lead from the ACC connection. |

Always thought the lighter circuit was hot at all times and accessory port was on the RAP circuit...
Retained Accessory Power (RAP)
After you turn the ignition off and remove the key, you
will still have electrical power to accessories such as the
power windows, audio steering wheel controls, clock,
sunroof (option), accessory power outlet and the radio
for up to 10 minutes. The instrument panel cluster lights
will stay on for a few seconds, then go out. Once you
open a door, the power will shut off.

I have my radar detector plugged in to the accessory port inside the lower console compartment (probably not what that's called) and it always stays on for a bit of time. I even park, go in to get food somewhere, and come back out to find it still on. I always thought it would shut off when the door opens too, but apparently not |

OK, for the sake of clarity, let's call position 1 the cigar lighter and position 2 the power outlet (like the FSM).  Are you guys saying that 2 remains powered after the ignition is off and the door is opened? I'll have to do some reading and testing but that contradicts what the excerpt from the owner's manual is saying... |

For clarity's sake, I am using the cigar lighter jack for this.
I called a local dealer who used to be an Olds dealer, and asked them if this was configurable in the Tech II. They told me it isn't, though I'm not sure how accurate that info is. I thought there was some configuration options for RAP in the Tech II though? I'm guessing the head unit gets it's power from that, and turns off based on a class2 signal when the door opens with ignition off?
Tigger,
That's interesting, I'll have to test that power jack and see if it behaves differently. I rarely have ever used it. If that turns off when the door opens, or when the ignition is switched off, then I think that solves the issue for my use case!

As far as I know, at least in the classic, the accessory jack is only on with key in and power on, and will shut off when the door is opened. Whereas the cigarette lighter on the drivers side remains powered on at all times. So the accessory or #2 jack should work in your case assuming the 2g is the same.

In the 2G it seems they're both on the RAP system, at least in my 2001. That said, I thought I read something on here of somebody disabling RAP in their car, though I'm not sure if that was a 1G or 2G. Of course, that would cause the radio to turn off with the key too, but I think I'm ok with that if it's easier than re-wiring one of the jacks to power off with the door.

You could pull the RAP relay (rear fuse block), that will most certainly disable RAP.  Sorry, haven't had much time for testing this week. Pulling that relay probably won't do what you want it to do though. I did notice my cell phone charger remained powered, plugged into either port, AFTER key out and door open. That would mean neither are on RAP, but they are on a timer of some sort. Hmm... |

Just found this looking through the owner's manual; Ashtrays and Cigarette Lighter
...
The cigarette lighter will only operate when the ignition
is in RUN and for 10 minutes after turning the ignition
off. If you would like the lighter to operate regardless of
the ignition position, and for unlimited periods of time,
see “Engine Compartment Bussed Electrical Center” in
the Index or see your dealer.
Accessory Power Outlet
...
The accessory power outlet will only operate when the
ignition is in RUN and for 10 minutes after turning the
ignition off. If you would like the accessory power
outlet to operate regardless of ignition position, and for
unlimited periods of time, see “Engine Compartment
Bussed Electrical Center” in the Index or see your dealer.
Engine Compartment Bussed Electrical Center (BEC)
...
Fuse 22 or 23 can be moved to the outer position to
provide continuous power to the accessory power outlet
or cigarette lighter when the ignition is not ON.
See your dealer for additional assistance, if needed. So, 10 minute delay or hot at all times may be your only options without rewiring... ...if it's easier than re-wiring one of the jacks to power off with the door. Running a power wire to one of the outlets form the RAP relay may me the easiest thing to do... |

This shows any time headunit is powered the accessory outlet is hot. Relay will follow RAP.  or you can probably just run a wire from the rap relay and it would handle the load just fine. |

I run my radar detector (Cobra Vedetta 650G SLR) to the ignition switch fuse underneath the backseat so it will turn on when the car is running or in ACC mode, and off as soon as moved out of one of those two modes. I drilled a small hole just large enough to fit the wire through it in the fuse box lid so there is no chance of the corners cutting it, and then I ran it to the side panel of the back left door, along the bottom until the pillar in line with the drivers seat and up from there to my rearview mirror.
Now I wired it for my Radar which sits directly below my rearview mirror, I also ran an accessory outlet with a quickcharge USB port to charge my phone under the dash.
I'm not sure if that helps in your application, but to my knowledge the acc/cigar outlets run hot all the time or delayed shut off- no other way around it, but maybe someone else figured that area out.

Hey Jason, you can tap ignition voltage and ground directly from the rear view mirror harness. Had a Passport (Cincinnati Microwave) wired in that way about 10 years ago, the plug is still tucked under the headliner, haha! |
