My 07 FLHP did not have a tach when I bought it so I scored one on eBay. I installed it yesterday and it works sweet with the exception of the ABS indicator staying lit continuously. I assume that the smaller of the two connectors is supposed to go to the ABS controller but my bike does not have ABS. Any suggestions in how to lose the light without opening up the tach?

 

Find out which pin is feeding it in your manual and pull the pin out of the connecter and tape it.
You may have to feed a signal to it. I don't know the logic behind it but you'll have to research it.

 

When you have ABS the light will come on till you reach 10mph [I think that's the speed close anyway] It then checks to see if there working and if everything is ok it goes out. You need to find the wire to that light and unhook it.
