I have a 2003 Harley Davidson soft tail (with a carburetor) that needs a new main wire harness. I recently purchased a harness for a 2000 model 'Deuce', and everything plugs in just like the old one except it (the Deuce) has a 8-pin connector going to the turn signal module instead of 12-pins (like the original). Any info anyone can give me regarding the differences in these harnesses would be helpful and greatly appreciated, however right now my biggest objective is to just get a spark to the spark plug so I can start the bike. Thanks in advance for any advice.
You have the wrong harness. The 2000's use a straight turn signal module. In 2001, HD integrated a factory security system into the bkes. When they did this, they integrated the security system into the turn signal module which is called a turn signal/security module (TSSM). You would see this in the wiring diagram if you had a FACTORY service manual.this is why you NEVER attempt any work on your own without a manual!!! A manual will pay for itself the first time it saves you from an experience like this. What was wrong with your original harness?.What's up with no spark, due to the harness?
