TC88 Ignition and Harness Kit / '99-'06 Twin Cams

The Daytona Twin Tec TC88 Ignition and Harness Kit is a complete replacement ignition system for '99-'06 carbureted Twin Cam 88 engines.

No Shipping to California.

There are two reasons to buy this kit: a stock ignition harness has failed, or a custom build needs an ignition system that does not depend on the original bike's wiring. Either way the problem is the same. Chasing a bad factory harness circuit by circuit costs more hours than replacing it, and building from scratch means you need connectors that match the sensors you have.

What Comes in the TC88 Kit

The harness includes stock connectors for the coil, MAP sensor, crank position sensor and diagnostic port, plus leads for ground, a 12 volt switched connection and a tach wire. That covers everything a carbureted Twin Cam 88 needs to run and to be diagnosed later. A more complete version is available that adds a Twin Cam coil and plug wires, which is the one to pick for a build starting with nothing.
