Also they are an odd shape, they're not round. Also there are two leads on each side. Do I have to connect both of them to the input wire or just one? How much of that black housing can I take off?
Uh-oh. Got my K2 emitters in today... which side is positive?

if you have a DMM, select diode test, and touch one probe to either side.
when you have it right the Emitter will light up slightly, EASY.

OR you could just read the datasheet

Notice that only one side has a corner; this is how you distinguish + and - sides, also there are 2 dummy contacts labelled NC = no connection.
BTW figure 2 is shown from the top of the emitter.

Oh yeah. I guess I could've done that! Thanks, I see how it works now. Why would they put those dummy contacts on there anyway? Can I just clip them off?

On the K2 the side that has a chamfer or cutoff corner is the Positive (Anode)

KDOG3, the heatsink slug should fit into the recess on top of the LED holder of the BOG module. Works very nicely for centering the LED. Please let us know if it doesn't. I'm working on a very similar mod. Just waiting on my K2 and BOG.

Just tried that. Unfortunatly, no dice. The LED "pit" is too large and the heatsink slug isn't deep enough. Looks like its going to take some dremel work to get it to fit properly.
