  • Headlamp wire gauge
  • Working on my headlamps now...6V '51 8N. Does anyone know what gauge the wire is for those lamps? I'd like to try to make my own ground wire and lamp pigtails...

  • Got some 14 gauge wire some connectors and we have working headlights! So glad they made things to last back then, as I believe these are original bulbs. I had to re-wire one of the grounds, but everything fired right up. Thanks for all the help!

  • Perhaps some folks do not know that LARGER wires bear SMALLER numbers.... 14 ga wire is larger than 16 ga wire .... 10 gauge wire is larger than 12 gauge wire..

    This is kind of second nature to most mechanics, but not to all.

    Have fun!!

  • I believe the OEM headlight wires are 16 GA a JMOR said but like most all OEM Ford wiring was cloth covered insulated with 'bullet-nose' style connectors on lighting. If you are doing a total restoration and want to be compliant, you'd need to get the ones Carpenter makes. You can still get bullet connectors. Kudos for wanting to D-I-Y but with or without a restoration I'd opt for the Dennis Carpenter exact-as-original wiring. Note this headlight wire (see LINK) has both the bullet nose connector that feeds the main wire to switch and the spade lug connector which fastens to a sealed beam headlamp screw terminal. The DC wires are also cut and made to exact length specs. One of the beauties of the 6V/POS GRN electrical system is that the lighting wires only required one main wire to feed each lamp with and the ground connection were simply a short connection to metal ground internally on each lamp. Some guys think they need to run two wires to each lamp. I disagree; if they wire them correctly making solid ground connections, no need to add more wires that can create a rat's nest. Your tractor, your call, just pointing out the facts.

  • It depends on the Wattage of thebulbs, but you are likely OK with 16 GA and larger
