Light dimmer switch???????

Most early Jeeps like your 63 CJ5 would use a switch. It is possible that maybe a previous owner might have made some changes.

No cj's have relays in the headlight system (which sucks), the switch on the floor in cj or any other vechile from that time period is for the high beams.

The foot switch is just that, a switch that puts juice to either the low or high beam circuits. It has 3 wires. 1 is the "hot" and the other 2 are the high and low.

Thanks for the info guys. I am installing the KC lights this week and am going to put a relay for the headlights and KC lights now.

Run the power feed to the relays to your alternator power stud (fused of course)and ground wires from the lights directly to the battery negative for the least voltage drop and brightest lights. Old Jeeps frequently have corroded grounds on the grill to headlight connections. Use the original wires out of the floor switch to trigger the relays and replace the connectors on the headlights (they're available at any good parts store cheap). Hope this helps, good luck!
