i have a 2 way alarm/remote start i purchased off ebay....i have the wires hooked up right according to diagrams...there is a 3rd ignition wire in the harness for the truck....but only 2 coming out of the alarm....

one ignition,one A/C (for ignition 2?)

do i need to hook up that 3rd ignition wire somehow? someone told me ide have to wire up a relay for the 3rd....how would i wire this relay up? the relay that came with the alarm has 4 wires total, 2 purple,1white and 1yellow wire....

How many ign outputa does it have?

How many acc outputs?

You should power up all the wires at the ignition harness. The only one that is not neccesary is the black green wire. That keeps the radio from turning on durring remote start.

I am not familiar with that r/s unit. On many less costly units you need to add relays to make everything work. Also check previous posts on this site for a wire diagram, it never hurts to have two. Many times the wires are incorrect on one so you can referance the other.

I am on a mobile device with a 3 in screen, so I cannot see the words on the diagram. I can look at it when I get home, if you can wait. make sure you have the corect wiring chart for the car as well.

Are you sure the wire is labeled a/c for air conditioning. The ac wire should not be ignition, because then the ac would be blowing while the car is trying to crank. Put your meter on it, when you try to remote start does the green wire on your alarm go on, then off, then on again?. If so then it is an acc 2 not ign 2. what wires on the vehicle do you have these acc and ign wires connected to?
