bought new turnsignal switch harness from Classic Parts of America product code 53-510 and installed it. When i unhitch the harness from the pickup the head lights and dash lights and dimmer work properly. when i rehook up the turnsignal harness to the truck and leave the lights off the blinkers work properly. when i turn on the lights and try the blinkers they work but not with the same spark as when the lights are off. when the lights are on and i use the turnsignal lights on the dash are on. they will kinda blink if i turn on them on. bad deal is the problems are not always the same. Yes i agree i am getting back feeding to the dash or to the new turn switch. i have checked all the grounds i can find. cleaned them and replaced with no help. i am going to order a wireing diagram for the truck from Classic parts $4.95 and study it for a while. thanks for the hlep any ideas are always helpfull.
