hey all - i need help trying to figure out a strange problem i am having with the trailer wiring hookup next to the hitch on my '98 4runner. basically, i have only been able to get current on the wire that controls the running lights of the trailer. i took a tail-light bulb and was testing the different wires in the connector. the running lights work, but brakes and turn signals do not. i can't find any fuses related to this connection, so i don't really know what to try next. any help is greatly appreciated. thanks,

wally
