I just bought a new civic yesterday and someone attempted to do a wire tuck on it and, well, they failed. So the idle sensor wiring is cut and not wired so the idle surges. Their are three wires going to it, the one wire thats completely gone is the orange one, i have looked it up and all i can find out about it is that its a negative. with that being said can i just ground it out and hook the other 2 wires up or does it have to be ran to the ecu? its pin number is 15. oh and its a y7 motor. here are some pictures of my new car too!

 

its actually pin number 13

 

bump..
