HARNESS,1971-2 T150 MAIN
Main wiring harness for the 1971-72 Triumph T150 Trident, PN 54959638.
This is the main wiring harness for the 1971-72 Trident triple, part number 54959638. It's the central nervous system of the bike's electrics, tying together the ignition, lighting, and charging circuits that run through the frame. The catalog also lists this under the older Lucas reference MC48PB, which is the same physical harness under its earlier numbering.

We don't have much more written down on this one beyond the description and the year span it covers, so if you're restoring a T150 from this era and your loom is cracked, brittle, or someone's been in there with electrical tape and a prayer, this is the number to work from. Give us a call if you want to double check it against what's actually on your bike before you order.
