WIRE HARNESS 68 500/650
1968 Triumph 500/650 wiring harness covering the headlamp, switches, and tail lamp circuits.
This is the complete wiring harness listed for 1968 Triumph twins in the 500 and 650 families. The catalog places it under the HEADLAMP, WIRING HARNESS, SWITCHES AND TAIL LAMP figure, which tells you it's the main loom running the lighting, switch, and tail lamp circuits for the bike rather than an ignition-only sub-harness.

It shows up under the alternate number WW19112 as well as 54953443, so if your old parts book or a box in the garage has one or the other written on it, they're pointing at the same harness. Our records only show this one appearing for the 1968 model year, so treat it as specific to that year's wiring setup rather than a catch-all for later bikes.
Because it touches the headlamp shell, the switch cluster, and the tail lamp all at once, it's worth pulling your existing harness out and comparing connector by connector before you commit to running the new one in. Call the shop if you want to talk through routing or connector matchups before you start.
