Here's a pictorial on the installation of the smart siren II on a bagger.

Here's the instructions for the installation.

This is the smart siren II,you can see the antenna wire on the side.

This is where the three pin plug was living before It was removed....just under the fuse box, under the left side cover.

This is the "Weather Tight" three pin connector.

Here you can see exactly where the siren will snap in. That is the only open spot under the left side cover....you cant miss it. You can spray a bit of silicone on your fingers and then rubit on the two clips to help the unit slide in. Do not plug in the connector before you install the unit......just place the unit in its spot...then insert the plug.

Here is the unit installed in its place. You can see its plugged in and you can see the empty hole under the unit itself.

This is where I placed the Velcro with the adhesive backing....you put one piece on the frame rail, and then center the skinny part of the antenna wire on it, and than capture it by placing the matching piece of Velcro over it. You can not let the skinny part of the wire antenna touch any metal or it will interfere with the transmission of the signal to the pager....if you have one.

Here is a pic of the finished product. Nice clean/neat install with the option of getting the pager. Its also nice to have the chirp arm/disarm feature.

Also, learned that on the Softail Deluxe 2008 the alarm mounts with the connector UP not down as in the (dis)tructions. It is held in place by the fender extender and the clips only add some tension but not "click" the unit in.

I would recheck the connection. They usually click in to lock the unit in so you don't loose it. Sometimes they need a good push to lock it in.

I just bought one for my 08 Ultra and it won't snap into place. it seems as if it's too big and if I force it, I think the clips will break. The box says 68328-06, but the siren itself says "Model number 68970-06." Anyone else have trouble pushing the siren in to place?

Try some silicone on it.

I had the same problem but just gave it a bit of a push and it snapped right in. Don't know how I will take it out if it ever needs to though.

I finally got it to snap in there.... Hot day, hot motor, and a little effort and it pushed in.
