Does anyone know what size tap the threads on automatic compression release is and is there a wiring harness already on a 2010 Ultra classic?Thanks

The ACR uses 12mm threads.

You can buy a wiring harness kit for the ACR's. You also have to do a download calibration. I am reasonably sure an ACR wiring harness does not exist on an Ultra Classic. See the attached PDF.

It is on the 2011 bikes as they had the 103" as an option and the wiring was put on the complete dresser line. 2010 year I am not sure of but I think it is there. Look for 2 unused plugs right behind the top of the a/c backing plate where there is a piece of metal going from 1 breather bolt to the other. There might be a plastic clip holding the 2 unused plugs for the ACR's. Digital tech or a Powervision will enable the ACR's. Enable them 1st so they do not get damaged.

According to the online parts catalog I often use, the 2010 eglides came with the wiring for the ACR's in the harness, with a dust cap over the connectors. I assume it was cheaper to do it that way than it would be to have two different harnesses, one with and one without. That's a common way of doing these things, and you will usually find other unused connectors if you look around enough.
