viper 5900 in '06 yukon denali

Hoping I can find some help from all you pros.  I am working on this install and am having a hard time with a couple of connections.  I dont want to sound to dumb by asking these but here I go.

1.  I have (2) 12v constants in the ignition harness, red and RED / white.  The remote start module needs (3) 12v high current constants.  Both of the ones in the ignition harness are fed off 40 amp fuses.  Since all three from the remote start module have 30 amp inline fuses, do I need to get the third 12v constant from somewhere else?

2.  I have (2) accessory wires, orange and brown.  The remote start module only has one accessory line.  I have read that I need to make sure and hook up the brown accessory line for everything to work correctly, but I am not sure how.  I guess I can use a relay but I need some directions in order to do it.

3.  I am having a hard time finding the + parking light wire.  Everything I read says that it is brown and in the drivers kick panel.  Nothing I test reads correctly.  I even went to the switch and tested the only brown wire that was there (it was a BROWN / white I think), and it tested 12v when I turned on the parking lights, but dropped down to almost nothing when I used the dash light dimmer.  I dont know where else to look or how I am missing it.

I appreciate any help that you can give me.  I usually dont have trouble with these types of things, but clearly this is an exception.  Thanks in advance.

1) get all 3 from the 2 wires at the harness....

2) I'm betting your unit has a negative output for your second accesory. Look in the 'relay" section for instruction on how to wire it.

3) use the negative light wire...  grey/black at the BCM brown plug, pin B2.

Thanks KarTuneMan.  I was wondering if I could just use the negative parking light wire, but everything I read said to use the positive brown wire.  Also I searched for the relay wiring and think I am ready to try it tomorrow.  I have a few more questions that I came up with as I was looking over what remains in the install.

4.  Is there anything special I have to do to wire a ghost switch?  Will any switch work?

5.  Do I need to use the toggle switch neutral safety switch input?  I do not know where to find the wire that it should be attached to or what color it is.

6.  How should I hook up my drivers seat position buttons so they adjust to the proper driver based on the remote that is used to disarm the car?

Thanks again for the help.

the neutral switch shoul be wired one side to ground and the other to the wire from the alarm (assuming it's dei) or you can just tap the neutral wire to the ground wire. if you really won't use the neutral switch. to wire a ghost switch, u can use any wire that can provise a momentary 12 volt positive pulse, eg hazrd light, brakes, park lights etc etc

OK.  Here is what's left.

Tap into the (-) horn output at the BCM.

Ground all modules, sirens, and neutral safety switch toggle.

Hook up 12v to brain, interface module, and window module.

Work my way through the neutral safety switch interface section of the install manual.

What I am going to leave for later.

Driver seat position with disarm.

Seat warmer interface.

Sunroof module.

Ghost switch.

I think I can get it finished after work tomorrow if I can get the answer to this question.  Should I run a new 12v feed from the battery to power the brain, interface module, and window module?  They are fused for 15a, 5a, and 20a respectfully.  The possibilities I see are running a new wire from the battery; tying into one of the two 12v at the ignition, which already have the three 12v remote start wires attached to them; or tying into the red 12v wire that feeds the fuse box on the side of the dash inside the drivers door, which already has a 20a in-line fused wire feeding audio video accessories such as steering wheel remote interface, onstar / bose sound system interface, and pioneer in dash dvd player.  I dont want to put too much on one line which is why I am wondering if I need a new line from the battery.  What size fuse should I put in-line at the battery and what gauge wire?

Thanks for helping me through this install.  I cant wait to try it all out.  It is going to be sweet!

Got it installed and tested.  Here is the problem I am having.

I cannot program the 457g module, therefore the doors do not lock or unlock when the alarm is armed or disarmed.  I searched and found references to a problem with the 457g, however could not find the specific information as to what it is doing and what the fix is.  When I try and program it, I do not get any led light at all on the unit.

Also the remote start will not get the car running.  It does not work unless I put the key in the ignition and turn it to run and then remote start.  Also, while it is under remote start, the headlights flash.  Is this normal and why?  Is the module faulty?  Thanks for everyones help.
