hi all i am new to the k5 world and to forums in general but especially to this one and i need a little help.
i rewired my 83 k5 used a EZ 21 circuit 18 fuse harness and have everything working great so far except my tail running lights and i cant figure it out. front running lights work fine with the switch pulled half out, i haven't installed any relay and am wondering if i need to? the truck is kind of a Frankenstein job has 400sb with a granny 4 spd i replaced the headlight switch brake switch and put in new fuses any help would be appreciated thanks.
