TSM32

A Harley-Davidson J1850 turn-signal and security-module replacement platform for custom builds and choppers.

In production

TSM32 is a Harley-Davidson-focused electronics platform aimed at builders who want to remove stock TSM/TSSM hardware and keep control over what the bike does.

The initial focus is J1850-based Harley-Davidson applications, especially custom builds and choppers where stock modules are removed as part of the wiring strategy. We are building it around stock-harness plug-in workflows and explicit compatibility notes.

TSM32 is a prototype project under active development. Claims are limited to what is implemented and tested; broader fitment remains a declared target until validated.
