I purchased a Harley Boom Audio Handle Bar Kit (p/n 76262-08) and the install is easy except for the wiring and no diagram is provided. Just confusing text! It looks like it needs a Hot, Switched Hot and Ground to connect it, I am replacing a HOG Tunes MA-2 system and this is how that was wired. But, Harley wants you to cut into the main harness; which is just not healthy. The wires to connect are RED, ORANGE and BLACK. Does anyone have any knowledge of this?
Thanks

 

Red goes to battery +
orange is switched +
black is ground

 

This setup was draining batteries so HD added a relay & different wiring using the harness, relay & a 12V adapter wire. I'll try to find the it as it has been posted here.
..

Here you go. page 5 shows the relay & 12V adapter with comes with the boom system (or maybe it's in the relay kit).

Thanks very much for the information and link.

The H-D instructions for the link above are for the Windshield mount version. Here is the Handlebar speaker installation: http://www.harley-davidson.com/en_US...ts/-J05522.pdf
(I found this by accident by just changing the pdf number!) in case someone else needs it.

These are different than what came with the unit.

Really useful site, just wish there were a search on it.

Thanks

 

How/why does this setup drain your battery? Unless the ignition or accessory switch is turned on, the orange and white wire should be off. If the orange and white wire is off... shouldnt the speakers be off?

I have an older version of the windshield mounted system and there is no mention of a relay or needing a relay.

 

apparently HD had some issues with power feeding back from the main power wire (battery) back through the remote turn on wire (orange/white) into the electrical system so they incorporated the relay to make sure no power got to the amp when the switch was turned off.

 

That sounds familiar.

 

How do you guys hear about this stuff? 90% of people who installed the 1st gen speaker system which doesnt mention a relay probably have no idea.

 

man I don't remember where I heard or saw it but it was a long time ago and it wasn't until golfblues said something that trigger it for me...

 

There was a long thread about this last year. There were different opinions because of the instruction change adding the relay. We got it right
