So I have my project car which is a 89 BMW 750il I decided to put the Viper remote start system in it. I hooked the power wires, grounded the ground and neutral safety wire( mines an automatic), door locks and parking lights. Everything worked except the remote start. checked my connections seamed correct to me but no crank. Off to the internet I came across this website and found a topic about some one installing the same unit in an Acura I believe. So I rewired my the same way you told that person. Hit the remote start and Holy ----- it cranked over not enough to start but it did try. I adjusted the crank time and tried again it started. Yeah Thank you guys. tested brake switch and ignition switch all working good. started soldering wires together, connected door wire, tach wire, siren I was on a roll things were going good. tried to start again no go no anything no error no flashing lights nothing. Reset controller by unplugging and thru menu just in case. try again nothing but this time the lights flash eight times neutral wire not grounded checked wire still grounded. reset box and tried again same thing. Tore the wiring back apart. Did you know the door switch sends a negative signal when open, which I hooked up to the controller, and a positive signal when closed? I didn't. So give it to me straight Doc is it possible that positive pulse fired the negative circuit in the controller?

No and that's normal for nearly all door switches so that hasn't fried it.
It wouldn't start because you have to discard the orange wire at H3, ACC and use IGN 2, pink/white at H3 and connect to the vehicle purple ACC wire.
wth has wiring a BMW to do with an Accord?
Join the BLACK/ white to your black grounding wire using a factory bolt.
Also is the silly switch with the black plug installed and turned on?

"wth has wiring a BMW to do with an Accord?" Absolutely nothing. I can't find the article now to reference but id did share some of the same things as mine, same controller and the same simple ignition switch( Off, Acc ,Ign, Crank).  I assumed that the basic features of the ignition switch would be the same on all vehicles.

The orange wire at H3 was hooked up to purple ACC when the car started before I permanently connected the wires. I will follow your suggestion and change out the orange wire for the pink/white wire this evening.

The BLACK/ white and the black wire are both grounded to the same place as the factory wiring harness under the dash.

And yes the small switch is installed and working.

Err really? The 5 series has 3 X ignition circuits! (Light green) all needing separate relays to fire up.
Also program the unit for comfort close, should close windows and roof on arming.

I do realize the complexity of BMW wiring especially on the 7 series with a V12. I was only trying to explain my thought process. I never said it was a good thought process.

Not to worry, we'll try and get you through this.
The lock triggers are POS (+), you'll need a plug-in 451 module to change the polarity.
