Can't find the dome lights

I put in a CS-2015FM in my 2002 Chevy Silverado LT this weekend.  I did pretty good with everything but the dome light.  I could not find a signal that controlled them.  I had the same problem with the parking lights, but found the headlights and used them instead.  I don't like that and since I have to go back in I want to hook up to the parking lights, any ideas?  The remote start works great, even with it being hooked up to the wait to start light.  It's a diesel and takes forever to warm up.  The Crime Stopper GMATAII worked to get around the Passlock II system, but setting the pot was a pain and the directions were a bit vague.

Again, any help on the dome light and parking light signals would be greatly appreciated.

Regards,

The park lights can be found at the brown wire at the keyless module + when on.  The keyless module is below the steering column.  Look in the middle plug.

For the dome lights, it depends on what you want it to do.  The purple at the light switch will detect all doors and is not affected by the dome delay.  There are several reasons why you would connect the dome light on this truck.  One is simply to just turn on the dome light when the doors unlock.  Another is to provide a pulse after shutdown to turn off the radio (rap).  And yet another is to re-arm the factory alarm.  Also you could be trying to detect it for an alarm or manual transmission remote starter.  Please be a little more specific as there are a few different ways to do these things.

Player69,

Thanks for the reply and sorry about being vague.  I am trying to get the dome light to turn on when I unlock.  I do want to pulse the rap and re-arm the factory alarm as well.  I actually like the dome delay and want to get it working with the new alarm if possible.   If I hook up to the door triggers (there is one for the drivers door and one for the other 3 at the BCM) and pulse them with the alarm dome light output via relay, will that get me there or should I use the purple wire you are talking about?  I have an automatic, so I no need there.  Are you saying that you can use the dome circuit as the sensor for entry?  Doesn't where I hooked into the door triggers do the same thing or is there an additional advantage.

Thanks for the help.

if you use the wire taht does not sense the delay on the domeligfht then the advantage is that you will not get an error chirp while arming if the domelight has not turned off yet, also the alarm will passively arm faster because the alarm will not have to wait till the domelight goes out. if you hook up your domelight supervision relay to just one wire you will have a much easier job instead of isolating multiple triggers off the bcm.

If the purple wire sees all doors it will trigger the alarm to sound when anydoor is opened and if your domelight wire (purple )has a relay connected to it from the domelifght supervision output of the alarm then your domelight will turn on when you disarm the alarm and shutoff when armed.

mobiletoys2002,

I have already hooked up the two door triggers to the door switch line on the alarm and diode isolated them.  I don't get the error chirp you are talking about, but the domelight supervision is not hooked to anything.  Are you saying I should hook up the domelight supervision to that same door trigger circuit as an input (via relay) to turn on the dome light?

I checked it out and the alarm goes crazy if any door is opened.  Now, if I hook up the alarm domelight wire to the same door trigger circuit that the alarm is hooked to, will it turn on the dome light?  I would think that the alarm says to turn on the light and the alarm then thinks a door is open.  I'm confused here.  I thought all I needed was a wire that would turn on the interior lights.  I put a relay on it to activate the lights whenever the alarm wants them on.  Would the purple wire at the switch perform this function?

Thanks

The chime sounds with the door closed when hooked up to the brown wire at the BCM.  I thought it was because I was hooked into the dome light at first and that the truck was thinking the door was open.  When I disconnect the dome circuit, the chime still went off both with the door open and close.  I don't understand why the truck turns on the chime when the door is closed, but it does.  If you turn on the parking lights it does it as well.  Chevy, go figure.

Player69,

Okay, I'll give it another shot.  I did that for the dome, but had found the brown wire at the BCM, so didn't chase the parking lights up there.  Do you know how the chime is controlled?  How does it know when the lights are on and the engine isn't?  Why does the chime go off if I sit in the truck with the doors closed and turn on the parking lights?  This has to be some new feature or could the door trigger be getting feedback and the truck thinks the door is open.  But, if that's the case, why doesn't it do it with the headlights?  Ahhh, the joy of the do it yourself lifestyle!  Just imagine how bad I would be if I didn't have an electronics degree and an engineering degree, or then again, maybe that is the problem. 

DONT THE DOME LIGHT LIGHT UP WHEN YOU UNLOCK YOUR DRIVER SIDE DOOR ON THAT YEAR MODEL TRUCK????

Superman,

Yes, when you use the factory remote.  WIth the new one it didn't, so you have to hook into the lights to make that happen.  It' does now.

On most (or all?) GM cars, the chime comes on with the parking lights, whenever the ignition is OFF......regardless of whether a door is opened or closed.  This is normal; the chime goes out when the key is switched on (or when the car is remote started).

A Toyota, for example, would only activate the chime if the ignition is off, the parking lights are on, AND a door is opened---but this is not the case with GM.

Also, let me get these other things straight.  The truck has a factory alarm.  You're installing a combination alarm and remote start.  You want domelight supervision---whether it be the factory supervision, or that built into your new unit.  You want to shut down the RAP if you turn the remote starter off.  And you want to re-arm the factory alarm if you turn the remote starter off.  Correct?

To shut down RAP without triggering your aftermarket alarm:  Cut any one of the door trigger wires in half; insert a diode inline, facing in the direction that allows the door trigger to still work.  Then attach your "pulse after shutdown" wire to the BCM side of the diode, and your alarm's door trigger wire to the "car" side of the diode.............the diode will prevent your new alarm from "seeing" the "pulse after shutdown,", but the GM's BCM will still be able to see it.

Domelight supervision:  Connect your new alarm's domelight supervision wire to the BCM side of that diode; the same place as the "pulse after shutdown."  This will give you (30 seconds?) of aftermarket supervision, followed by whatever the factory delay is.  If you want the delay to be just like factory, split your alarm's unlock wire with two diodes-----send one to the normal unlock wire, and the other to the BCM side of that door trigger wire------the car will think a door has opened, thus activating the factory delay.

Factory re-arm:  There are only two ways to arm the factory alarm.  1.  Press Lock on the factory keyless.  2.  While any door is open, press the power lock button on the door panel, and close the door.  ------------  I tried to diode-split the alarm's lock output.....one to the lock wire and the other to one of the door triggers.....but this didn't work for me.  I think the BCM needs to see the door being opened BEFORE the lock button is pressed.  If you have the time and energy, you could probably duplicate this using some pulse timers or something, which I've never tried before.  Or solder into the factory remote, bury it under the dash, and trip it with a relay.  For now, though, you'll need to get in the habit of locking the doors before you exit the car, and then arm your aftermarket system with the remote.

I want to shut down the RAP if I turn the remote starter off.  And I want to re-arm the factory alarm if I turn the remote starter off.  Correct

I'll to the split with the diode at the BCM for the RAP.  I will look at inserting the factory remote, but might try to remember to lock before I close the door.  I have the dome supervision working with the aftermarket through a relay.  Seems to do all I need, but I might try the split just to see. 

Thanks for all the input.
