gray / YELLOW and RED / black are both accessories and both need to be powered during remote start.  BLACK/ green does not need to be powered during remote start, all it does is turn on the radio.  blue/green should be ignition, and yellow or GREEN/ purple for 12volts.

oh, and RED / blue for starter.

If i remember right gray / YELLOW was the blower motor wire and is accessory, so it must be powered but doesn't need to during start. It can be wires as ignition or accessory but it must be powered...Mike M2

vitrox has it right.--The gray / YELLOW is for the heater........ power that up as an accessory.--The RED / black, I don't know what it's for, but if you don't power it up, you'll get an ABS light during remote start. Power it up as an accessory.--The BLACK/ green is for the radio and wipers, and those are two things you don't want turning on during remote start......... you should be fine to just leave it unpowered.--You didn't mention what brand of unit you're installing, but most have 2 ignition outputs, and 1 accessory output.Simply connect the ignition 2 output to the RED / black on the Ford, but if the remote starter's programming menu allows it, program it for "off during crank."NOTE: As others here have said, never go hooking stuff up just because a tech sheet (or us!) tell you it's the right wire...... a good installer ALWAYS TESTS the wires to verify that they're right.

ok i tested the gray / YELLOW wire and the RED / black to see what they were doing during remote start. both power up during the key turning the truck on. when i remote start my truck the gray / YELLOW powered up just like it did with the key. the RED / black did not power up like it did with the key. so i powered that one up and now my gauges turn on like they are suppose to and do not have that delay of 15 secs. so should that fix my problem or may there be more wires that i need to check?
