You need to supply the ignition live feed, i.e. position 2 to a push to make switch and then from the push to make switch to the remote starter wire on ignition position 3.

Using the correct gauge of wire of course.

Red will be "Hot all the time" It's either the Blue/Black or yellow and black for the ignition and the starter is the other or vice versa, can't remember off hand!

Check for sure using a meter!
