2017 SG with 4.3 HU
 

Im trying to figure out if the 4.3 HU in a 2017 has output for rear speakers. As far as I can tell HD quit selling the wiring harness for it in '13. I ask the guy in parts today and all he could do was say words "fosgate" or Harley trying to sell me some system.
I bought some lids with speaker mounts. I will eventually replace the entire audio on this bike but for now Im spending a lot money on other things. So I would like to just throw a pair of speakers back there and get the HU flashed.
Maybe this weekend I'll pull the faring off and have a look but hopefully somebody here knows. 2 Dallas Harley stores don't know. :/
Thx

yes it does
