Hello Ratsun guys I have a big problem that I need you help, well my situation is this I did the engine wire tuck on my 1974 Datsun 620 everything was going well but the only thing that I had to extend was all 4 headlight wires (low & high) using but connectors and I re wired averything back again, got all the components working good starter, alternator, distributor but my headlights are the only thing that is not working at this point ( won't turn on ) the rest of the lights ( interior and rear ) are working good . I verified fuse box and fuses and they all good check wires and they are properly connected .I'm running out of options here do you think that could be the lamp relay or light switch ??? O and also I did removed the 4 wires that goes to the lamp relay on the front next to the radiator that was connected with a ground wire, and I put it back according to the diagram that I have for the 620 but still not working PLEASE NEED HELP.
