i have a 98 civic and im swappin in a ls motor i used the wire harness from an ex 5sp and hooked it all up i forgot to hook up the one clip to the fuel on the fire wall it looks to me like it on the fuel catch can, if that is what it is

is there any way to wire that to a switch or does any one know which color wires from the harness go there because i cant find the clip on the harness


thanks
