Thank all of you for your responses. I need to study them and start sorting out the problem. What I have done so far probably doesn't make sense. There were 2 wires in addition to the power wire that could reach the outgoing switch terminal so made a split there. The other switch terminal had the power wire attached. Underneath the truck there were 2 wires that could join the brake wire to the taillights. Anyway, using the wiring diagram I need to sort out the miscellaneous wires.
I use a short strck to keep the brake pedal depressed when checking lights. I made a split here. Both brake lights work when the pedal is depressed. The parking lights work f and r The left turning signals work f and r. When the right turning signals are activated both the left and right rear signals blink.. The right front blinks only while both rear turn signals blink. As I said i need ro go back and sort using the wiring diagram.
