i bought a pair of jdm yellow fogs. the assembly's are in the bumber.but now i have to wire it up. thats my problem. of course there is a fuse and a relay.the switch has a wire going to the foglights then one with a little harness and a ground. now the one with the harness says on the diagram that its a positive wire. can i jus cut of the harness and extend some wire to the main positive. bc i figue if its all grounded power is going from relay to switch then to the lights then it should work. but im unsure and wanna get it right the first time. oh and the lights are for a 99-00 si
