Step #11:   The last connection to the Slave (front) amplifier is to the second set of 

speakers in your system.

 

 If using Hogtunes lids

: the harness that comes with the lids will 

work its way up the bike, and plug right into the amplified out “pigtail” 
on the Slave (front) amplifier. 

 

 If you are installing this on a Road Glide Ultra and have the Wild Boar 
Audio “WBAURH” Ultra Rear Harness, please go to the manual that 
came in that box.

 

 In all other cases (such as lower glove box speakers) you will use the 
“ACC” harness that came in this kit that has a 4 pin black plug on 
one end, and no plug on the other. This will plug into the amplified out 
“pigtail” on the Slave (right side) amplifier and you will “hardwire” 
your second set of speakers to this harness. The wires on the supplied 
ACC harness are clearly labeled which will make wiring easy, but to 
avoid unnecessary warranty calls, please take EXTRA CARE of joining 
the wires together.

Step #12:   If your comfortable removing and re-installing the fuel tank, the wires 

can go in the factory wire “chase”. Alternatively, you can loosen the 
tank’s “chrome console” and run wires up and over the gas tank, but 
under the tank’s chrome console. There is a provision on the front of 
the tank console for wires to pass. 

NOTE:

 During some routine bike 

services, the fuel tank will be removed. Having the wires going up and 
over the tank could be an inconvenience for the technician.  

Step #13:   Attach the amp’s brown wire to the negative (-) battery terminal and  

the amp’s red wire to the positive (+) battery terminal. The factory  
battery wires are also re-installed at this point. When attaching the 
power and ground wires, it is always  a good practice to do the 
negative first. When the positive connector touches the battery, some 
sparking is normal. This is a function of the capacitors in the amplifiers 
charging up.

    

This amplifier comes set up to power front speakers and  

speakers either in lids, or fairing lower glove boxes only. If you 

are installing this amplifier on a Road Glide Ultra, you will need 

a Wild Boar Audio “WBAURH” Ultra Rear Harness if you want 

to power speakers in factory rear speaker “pods”, and have the 

radio’s fader function properly.
