4 wheel drive light (Remote Start)

I installed a Audiovox Prestige Platinum 996 on a 1999 Ford Expedition.  Everything is working just fine, but when you remote start the truck, the 4x4 light on the dash continues to blink.  This does not occur when you start the truck with the original factory car key.

I noticed that this truck has 3 ignition wires, but the remote start only requires the use of the 1st and 2nd.  Could this be the problem?

Please Advise........

YES! You must hook up all ignition wires. Alarms have usually 2 because they try to fit the standard for most cars out there. You need to add a ignition wire. Easiest way is to splice off one ignition wire, wire that to pin 85 on relay, 86 and 87 to +12V, and 30 to the ignition you need to power up. Most ignitions power things like fuel, spark, and tranny. If you drive the car with that light on, there is a possiblilty you can damage the transmission.

Thanks for all your help.  It sounds like I need to hook up another relay for the ignition or accessory wire that is left.  I will test the wire just to make sure that it is correct and hook up the relay accordingly.

Thanks
