viper 5904 remote start , 72 gmc pickup

I am installing a 5904 Viper alarm and remote start system in my 72 GMC pickup. The truck is a ground up rebuild about 90% complete. A new wiring harness is installed and seems to be working as it should. I have installed the viper system and had all the functions working including the remote start. The shock and the field disturbance sensors had not been installed. The is being worked on in other areas as it is not ready to be driven. I start the truck occasionally just for the hell of it. I haven't cranked it in a few days. The only work done on the alarm was the hooking up of the shock sensor. Without knowing it I adjusted the senor past it's limit and it went dead. I realized what I had done, adjusted the sensor back in the normal range and it was working fine. Just for the hell of it I hit the remote start button and got a "toggle switch off" prompt. I re checked the toggle switch and neutral safety wire and everything seemed fine. I bypassed the switch moved the neutral safety wire to a new location checked the wires third and forth time. Feeling desperate I open the brain and jumped the toggle contacts and grounded the neutral safety position on the circuit board, hit the remote start button and got the "toggle switch off" prompt again. I don't have a clue at this point. Any help would be greatly appreciated. All other alarm functions seem to work fine. I don't know if this matters in anyway but i typically disconnect the battery if I'm not at the shop.Eddie Meredith

Here is the update.  If I ground the toggle the remote starts right up.  The nuetral safety seems to be okay although the brain is not sending a negative signal to the toggle.  Is there a reset on the viper brain?

Any ideas would help!

Thanks

Thanks kreg357 for the PMEddie Meredith

hello I have the same problem as you, can you tell me as you have solved?

I didn't really fix it. I simply provided a new ground to the switch. The problem is in the brain. I hope this helpsEddie Meredith

What you have done is give ground to the switch wire right? I'll try as soon as u confirm it. regards

hello, the switchboard is wrong as to recognize the switch will I have to put - the car chassis. Then my car is a honda civic typer R FN2 2007 and no assembly diagrams civic which is about the same changes. This is my connector: You have blue thread and put in the wiring diagrams http://www.commandocaralarms.com/wiring/2006-2008/honda/civic/945.html connect it as follows: Remote Start, 10-pin heavy gauge connector -H3/1:Pink, (+) Ignition 1 input/output. [Conection ignition harness start button] -H3/2:RED / White, (+) Fused (30A) ignition 2 / Flex relay input 87. [12V white] -H3/3:Orange, (+) Accessory Output.

-H3/4:Violet, (+) Starter output (car side of the starter kill). [Cotar cable amarillo parte del coche y conectar]

-H3/5:Green, (+) Starter input (key side of the starter kill). [Conectar cable amarillo cortado parte de la llave]

-H3/6:Red, (+) Fused (30A)ignition 1 input. [Conectar (+) 12 VDC battery Cable White]

-H3/7:Pink/White, (+) Ignition 2/ Flex Relay output. [Conection Cable Red ignition harness]

-H3/8:Pink/Black, (+) Flex relay input 87a key side [No Conection]

-H3/9:RED / Black, (+) Fused (30A) Accessory/Starter input. [Conection (+) 12 VDC battery Cable White]

-H3/10: No connection.

with these connections try to boot without turning on the instrument panel and is a long time.

Key positions of my car are:

Position Accessories:

Yellow: this wire is 0V which is bridged to the viper: H3 / 4 Violet and H3 / 5: Green.

Red 12

Orange: 0V

Position Contact:

Yellow: 12V

Red 12

I did supply a new chassis ground to the switchEddie Meredith

Is this 72 GMC pickup a carb engine? If so you wont be able to get a good reliable start everytime.
