you can get the connector with the wires from most any local auto
parts store.
Pico is the brand, and it is a black plastic connector with the wires
already installed into it. and about six inches of wire hanging out
the back. one Gotcha: all the wires are the same color. :( about $3
each.  part number is 5407PT, "headlight connector, universal 3-wire".

or you can order them from camelback vw, a dealer in phoenix, az, that
does good work in its parts dept. 800-876-5199. ask for ernie or
larry.
part number of plastic connector (white) is 161-941-165. it's called a
'housing', and it's $6.42 EACH!!!!! sheesh. and this is with NO wires!
want wires? they are separate and extra cost.
000-979-206. yellow wires about a foot long, with connectors on both
ends. lotta good that does ... you have to snip one end off and push
the other end into the housing/connector. sitting down? cost of wire
(one each. 1. uno) is $2.63. for one. and you need THREE per
housing/connector. unless you get smart and get only two and cut them
in half. then you have four wires, just shorter. ;)

good luck!
