Trying to put a tach on my 06 Deluxe EFI. Anyone know where the signal connection goes? I think the power goes in the fuse box P&A fuse location.

 

if its like a 04 softtail. the power goes down to the fuse box,and get hooked up and the signal wire goes to the plug on the bottom of the speedo. it tells you which numbered hole in the instructions. the plug has a 1 on one side i think. (for example it will tell you hole 6,and you count from the 1 hole over six places and thats where it goes) i remember it was confusing. good luck. i did the install for some one else, or i would go out and check it for you.
