pins only no wires?
If there's wires just look at the color diagram.
If not, which I assume is the case, you're looking for the following
Running, Brake/blinker, reverse, ground, ground *yes two grounds*
Easy way to find it is to take a volt meter and check for continuity between pins. You'll find the two grounds this way. Once you do that connect each one to a 9v battery and figure out which of the other pins go to what.
Looks like they have a pigtail for it. Part number 68680
They don't use normal color conventions which sucks, but it'll probably be
A-reverse
B-tail/running
C-Blinker
D/E-grounds
flip it upside down so it's A/B grounds etc.
I think your best bet will be to buy the sealed pigtail from them and check it with a 9v battery to see what is what and then wire it up
