Electrical troubleshooting requires at least a multimeter without it is almost impossible to determine the problem. You want to focus on the question "why". Not "where". So you find out why the bulbs are not lighting up when you activate the switches. First activate the low beam then measure voltage on the wires if it is getting any. If there is voltage you know it is the bulbs. In electrical problems you must have an open mentality meaning don't assume right away that all the those bulbs can't be out at the same time. If the bulbs are good then look for a black ground wire. Tap a wire to it to then momentarily touch it to the body of the vehicle. It the bulbs lit up then it is a ground wire not making contact. Don't look for where it it just tap another wire to the ground. Fixing electrical problem doesnt always mean finding where the problem is but correcting the problem is just as good or better since you would have a better ground connection vice versa.
