I am looking at installing a cruise control on my 2006 flhtci. I got a quote of $712.80 for Harley shop to do this. Sounds really expensive. I was wondering how hard is it to install myself. I looked at the pdf instructions on harley site and it looked like medium difficulty. Has anyone installed one that can help me decide if I should try to tackle this? Also does it need to be programmed? Just wondered if thats why price is so much.
