viper 5704 on 2003 cavalier

Parking lights: You want the White output. The isolation wire is only used when you need to isolate the parking light output from the switch. Defogger: You need to test the rear defogger activation in the car. If the wire shows momentary ground only with the button pressed then it is pulsed. If you press and release the switch and the ground stays active then it is latched.Kenny

Damn Kenny, you beat me again, it's a brown POS (+) on a blue plug at the BCM so as Kenny says disregard the WHITE/ brown, only use the white and make it's output POS (+) via the internal fuse. Pulse = momentary. Latched = switched constantly.

You basically  you have to get behind where the switch is located and meter the wires going to it. It should read:

12 volts then when you press the button it drops to 0 Volts then jumps back to 12 volts. This is called a (-) pulsed defroster.

12 volts then when you press the button and drops to 0 volts and stays there. This is (-) latching defroster.

0 volts then when you press the button it jumps to 12 volts. This is a (+) latched defrost and may requires a relay to switch polarity.

When all else fails, Read the Instructions

ok i found the brown wire at bcm. how do i change that fuse? right now it seems as its not plugged in to anything. i have 3 female slots on the left in a vertical line and the fuse sitting vertically to the right of that line. the only thing i see in the installation manual involves replacing the fuse with a resistor and using both the white and the WHITE/ brown isolation wire. by the way i am using the 5901 install guide as a reference. i could not find one for the 5704 anywhere. only found the quick reference for the 5704. does anyone have access to a complete install guide for the 5704?

and nevermind, sorry. i looked at the 5704 quick reference again and its shown in the diagram..

any ideas on how i can remote start but have the stereo stay off until i actually get in the car? i have a pioneer x6500bt. it trys to auto pair with my iphone via bluetooth when it turns on but when i remote start i am not in bluetooth range of my car. so when i actually get into my car, i have to manually pair my phone. i know this seems like a minor annoyance but anyone have any ideas?

To be honest, no. I have a "link to cell" at home which reaches to where my car is parked. I have exactly the same problem of R/Sing the car, of getting 100 yards down the road and wondering why my BT display doesn't say "HOWARD".

use a relay to break the red wire from the radio during remote start will keep the radio off until you deactivate the remote start. 85: ground when running 86: ignition 87a & 30: split the red wire at the radio between the two pins.

i have a 2003 cavalier, pioneer x6500bt and a viper 5704. i want to have the stereo only get power when the car alarm is disarmed and running. reason being, when i remote start my car, the stereo turns on and attempts to pair via bluetooth to my iphone, but i am never in bluetooth range when i remote start the car so i have to manually pair my phone every time now. the 5704 has a -500mA ground when armed wire and i am hoping to use this with a relay. heres what ive come up with: im not sure what to energize the coil with though. im worried about the voltage spike if i use a 12v+ on the 85 pin. any help would be appreciated

didnt think about splitting the wire at the stereo, that makes a lot more sense than what i came up with. as far as 85 and 86, is there a way i can use that ground when armed wire instead? id prefer it to work off of that instead of whether the remote start is active.
