PROFESSIONAL INSTALLATION REQUIRED!
You received a "ice cube" that is an LED driver its not an option you MUST USE IT or your light will burn up!
If you have a double LOKI-2, ACME-2 or BURRIS-2 you HAVE to USE one driver PER light (one on each wire lead)!
The short wire end from the cube is the OUTPUT and goes to the light, the LONG wire is the input and connects to your battery.
There is a red and black wire inside the black cable!
If you happen to have a remote, one end of the remote receiver is labeled "LED" that is the output! Put the remote receiver BEFORE the "ice cube"
If you have a light that has two sets of wires (Loki 2, Burris 2 or Acme 2) You have to use both drivers.
On the input side of those drivers (long wire off driver is the input) you can parallel (connect the reds and blacks together) and wire them to the remote or switch.
