Hi. is there a relay for the acr's. I put them on my 09 classic with acr heads. and most times they work than they don't. they were activated through my ecm. thanks.

 

Do you buy the harness and how did you hook up the ACR's to come on?
Did you do anything to the ECM then or?
Bought a set of heads and the harness and trying to get my head around this myself and what will be entailed.

 

Not a fan of manual compression releases?

 

I'm not, don't want to burn my knuckles.

 

If they were wired with the HD harness, nothing after the fuse block.
The instructions do seem confusing, but once you do it, it will make sense.
You are just moving a couple of wires around to tie in the ACRs to the fuel pump circuit.
The hardest part is working behind the fuse block to plug and unplug everything.

 

Many, including myself, have wired their ACRs directly to the starter circuit. When the starter button is pushed the ACRs are open ... pretty simple to do.

 

You will need a a tuner that enables them or take it to the dealer and have them do it. The harness is straight forward other than mucking with some pins in the one connector. I did this last winter with my 107 build.

 

Is this a feature that is already in the stock 09 ECM then or?

 

I bought a 2014 motor to put in my 07 and the dealer activated mine and with the harness the whole thing was $215.00. Works perfectly.

 

Yep ...thi is easy and works
