I have a 51 Wagon. I am adding turning signals and the passenger rear tail light. Have it rewired with these requirements added in when I ordered the wiring harness. The turn signal came with it but seperate. I think I have it wired up but it came with no flasher unit or wiring to a positive feed. I bough an old turn signal unit with a flasher an wired it to the new. but I do not have a fuesable link between it and the positive feed. What size fuze do I need and can someone show me the wiring from the flasher unit to the positivbe feed
