wiring problem for plow lights

i have a 95 gmc 1500 with separate lines for high and low beam.the directions i have are for dual beam. i hooked up my plow lights to my truck lights and then to a switch and when i turn on that switch while my lights on the truck are on, the plow lights dont come on and my truck lights dim very bad and go out for a few seconds then back on dim and off.
i guess i need to interrupt the circuit, but i cant understand the directions on fishers web site. can someone explain to me how to do this?
