According to my 2007 FLH series HD service manual, the O/w wire in the right switch housing is a ground wire that ends at one end to the triple tree. The schematic also traces the O/w from left switch housing, tach and speedo to the main wiring connector.

 

Thanks Breeze. I saw pretty much the same thing on the wiring diagrams I was able to find on the internet. I'm still wondering how it was wired in the factory kit? I'm a little hesitant to ground the wire since I paid $830 for the kit.

When I turn on the CC the little speedo icon lights up orange. I took the bike for a ride yesterday and was not able to engage the CC so I'm not sure what the problem is if it isn't the orange wire. Maybe it needs some dealer programming to make it work? I didn't have the front cowling or headlight installed.

Where do you live in Middle Georgia? I'm in Hawkinsville.

 

Test to see if I can attach a PDF file.

Whoops, didn't see your message with attachments. Still trying to learn the forum nuts and bolts.

 

I just did a quick search, and this link let me get all the way to checkout with an '07 manual. Note: manuals have wiring diagrams, but there's also an electrical manual. I think I have a pdf of it also, I'll look.

Official Harley Davidson Touring Service Manual from Parts and Accessories

 

PDF of cruise control section '07 electrical manual.

 

Thanks Breeze. I printed the diagnostic instructions you sent me and went through the steps, but the speedo icon never lit up. Next I rolled the dice and connected the O/W wire from the set/res switch to the other O/W wire in the terminal block and tried the diagnostics again. This time I got 3 slow flashes followed by 3 quick flashes. I got the soldering iron out and made the connection permanent.

I then warmed up the engine and went through the initialization procedure. I had the green speedo icon, heard the engine rev a little then the icon turned orange. Everything worked as it should so I put the cowling, etc. back together and headed down Upper River Road, the road the women's prison is on. I know it has some hills which is a good test of the cruise. It worked perfectly, I now have cruise control. Thanks again for all your help. I'm on R&R from my current assignment on Alaska's North Slope and really wanted to get this finished before I returned to the job.

 

I don't know so much, but I do pack rat stuff away for possible future use. :nerd

 

Nobody knows it all. But everybody knows something. When we add it all up and share it, it amounts to a helluva lot.

If you click on the PDF icons in reply #5 above, the instructions will open. I've changed computers and such in the last 7 yrs. but may still be able to find my data. Also, it seems like I have forgotten more in the last 5 yrs. than I learned in the last 40. Edit: I remembered that the 2007 cruise control is a Unicorn, different than 2006 and 2008 because it was the 1st year of 96" & 6 speed.

 

I cant find a single diagram that shows the exact terminal in the Molex connector that I plug the cruise control switch into on the faring cap into!!
