1966 Ford F100 hazzard flasher and turn signal




Hello everyone,
yesterday i was working again at my Ford. With the wiring is everything now mostly everything good. The only thing is that i dont have working brakelights. When i put the cable we're it belongs like it showed in the wiring diagram the only thing happend is that the turnsignal on the driverside is flashing but only in the back. Is it normal that when i have a hazzard flasher relais that i also have the original turn signal relais and both are connected together. The truck used also under the Dash the original connector wiring like it shows in the wiring diagram.
Lots of greetings Alexander

I'm not really following your question but.... My '65 has no hazard light system, An option I believe. Any frayed wires are bad. The brake light circuit feeds through the turn signal switch, so that all has to be good.
