Ok i have them in a pillar. Ive already connected them to the sunroof wire thingy. And grounded it on the screw down by the fuse box. I routed the vacuum hose and the wire that goes to the o2 sensordown near the fuse box. Is there a hole where i can feed the vacuum hose and the wire to the o2 sensor into the engine area so i can umm hook them up lol?
