Hi all.
Adding a radio to my Dyna.
I know most do it without upgrading anything. But if you have added a radio to your dyna where did you tie in for power?
I'm thinking running from my electrical box off a keyed power source and running a power supply under the tank to the front end.

If you have been thru this before please post what method you used.
Thanks

 

i have to check my manual but i thought there was 1 keyed and 1 constant
port under the seat to plug in to.

 

Jay,
Not that I've installed a radio on my Dyna but did it in my car.

Some radio's have two wires that have to be connected to a 12 V power source:

radio's red wire runs to ACC switch controled power in car

radio' yellow wire runs to constant power (for radio memory purposes) in car

According to the wiring diagram I have in my database, your 2006 FXDWG has an accessory plug underneath the saddle. It's a four pin connector.

pin 1 and 3 are accessory switch controlled power lines, pin 4 is ground.

If your radio needs constant power here's how I would connect it (see image):

option #1:
yellow to blue/gray wire at first fuse box connection "A" or "C" or to the hot wired B+ connector (not fused!!) using the H-D adapter harness (link)
red to pin 1 or 3 at acc plug using a Deutsch connector (link)
black to pin 4 at acc plug using a Deutsch connector (link)

option # 2:
yellow to pin "A" at first fuse box
red to pin "S" at second fuse box
black to a ground bolt at the fuse box or "-pole" at battery using a ring terminal

Edit: I added the B+ hot wired plug to the wiring diagram

 

on my 11 wg there is 2 plugs under the seat. one single wire that is battery positive and the other is 4 wire plug with 2 keyed positive and ground wires. i bought an adapter from harley so i didnt have to cut any of the original wires on the bike. see pic for plug i bought from harley. it was an accessory plug for a touring bike. if you ask for the accessory plug adaper for a dyna, they give you the plug for battery positive. i used 1 circuit from that plug to run an amp.

 

I just wired in an amplifier, straight to the battery, and connected the remote wire to one of the key-on wires.

 

Yep, you're right! That plug is called the B+ plug and is "hot wired". I added this plug to the wiring diagram in my previous post. Attention: this B+ hot wire is not fused!

Here are two older posts covering the connectors subject:

 

depends on the radio, you can hard wire in the power and neg and then tap the remote line off anything that turns on and off with the bike. i tapped mine off the tach ligh

 

I guess you added a fuse holder to the line that runs to the battery?

 

Yup, with a 10A fuse... Tucked everything in, can't see any of it.

 

there is a inline fuse yes sir! have to have that!!!
