starter kill relay

My vehicle has 2 started wires, one through a common MUX wire using a resistor. The other being a dedicated wire. My remote starter has a starter kill output. Do I use the starter kill relay for only the dedicated wire? Do I use the first starter kill relay to shut down my second starter signal??

what vechicle do you have? but yeah you use the primary because the secondary usually does the accesory if its a newer vechicle. only when you install remote starters in these vechicle do you use the second. cut the first one try to crank it over if it doesnt crank over then bam you got it. if not then you got to use two relays and diode isolate the starter kill wire coming from the alrm but first try the cutting of the primary starter cable.installers do it best. we got the magic hands!

and i do mean by the first is the dedicated.installers do it best. we got the magic hands!

Thanks for the info. I am installing a remote starter. I should have stated that. I installed it today, haven't been able to test it yet though. I used the starter kill relay only on the dedicated starter wire. The secondary MUX, that also controls accessory, I did not cut. I left it. Also, I installed the starter kill relay BEFORE my RS starter connection. Meaning that the key will not funcion,but my remote start will still?? Should the starter kill relay go inline AFTER both of these? Or where I've put it?
