Thanks or the post. In the pics and on the DK Cutoms site it looks like they have a ground wire. I'm curious where you grounded them, especially the front one, or if you didn't. Thanks for the tips, I really appreciate it. Maybe I'll use a straw when I'm on the ground putting on the front one.

 

If I'm not mistaken depending on what year you may not have the ground

 

I've got the Vied's, and the instructions say that the ground is needed for 09 and up Touring models only, so I'd assume that the Xied's are the same.

 

This ^

I didn't unbolt it at first, but later took one bolt out and screwed the ground cable to it.
Mine is a 2012, think they are different this year forward

And to the other guy, I wouldn't put xied's in then dyno
I would take them out, get the dyno, then put them in

The xieds are to trick it into adding more fuel
Harley has to dyno/tune things to the lean side for EPA, put the xieds in after to richen it back up

 

Oh, and when I was done, I hid it kind of back behind plastic holder, lightly wrapped electrical tape around everything to keep it clean, and tie wrapped it out of view.

 

Just checked, No ground on my 2010 FXD

 

Great, no ground makes life a lot easier. This was the only thread about xieds and dyna's specifically so this is a big help. I just ordered mine. Will put them, and my slip ons, on this week. Anything else I should know? Thanks guys.

 

Think Nightrider says 2012 and up, the Dyna's now use the Touring ones

One under the seat (with a ground I grabbed right behind the rear cylinder)
One in front under the voltage regulator. I put in the chrome one below, and put the ground from the front one behind one of the screws

 

Thanks, I have a couple ideas about the vol reg, I'll have to explore under the seat a bit. I will call dk cust or nightrider tomorrow to make sure. Thanks again.

 

Just installed mine on 2013 wide glide, both have grounds. Rear i grounded to battery, front to voltage regulator bolt.
