power lock pump 4kq help

[WAUFX at aol.com]

ok folks-

after a night of absolute nightmarish nonsense with door handles and truck
shocks and power locks, i have, sitting in front on me, the power lock pump
for my 86 4kq.

now. the stupid part.

how in the holy hell do i test this thing? i have wires running from my
battery booster pac, one from + one from -, obviously. now on the back of the
pump, there are 3 male things sticking out from the electrical connector
part. as you can see in the picture at
http://www.uvm.edu/~mkbigelo/powerpump.JPG (note the capitals in JPG), there
are the 3 connections. in relation to how the pump is positioned in that
picture, which one do i touch the + wire to and which one gets the ground and
which one get nothing?

i tried a whole bunch of different combinations and got a green spark when i
put the ground on 2 and the hot on 3, the connections being numbered 1, 2,
and 3 from left to right as seen in the picture. and nothing anywhere else.

thanks audifans...
