You probaly have the same light as I. If you don't have the instruction sheet check out [email protected]
or e mail me & I will try scanning one for you. The trick to resetting or programing is removing power from the light itself. I found this connection on the backside of the fuse panel in front,outside, leftside elect compartment. If you can ID the fuse you could do that as well. Pull the connector off removing power to light, then press & hold remote switch (the red LED will come on) then replace light power. After a few seconds the LED will blink (some units will not) then release switch. unit should be ready to go.
