Wiring taillights and turn signals 1948 Packard woody

Posted by Packwagon On 2023/8/1 0:42:55

I’ve been completing my wiring. It has been quite a job. How can I check that I’ve got power to my lights and signals.? Where do I start and in what sequence?
My original car wiring has 3 wires coming from the column under the dash. I’m not sure how to connect it up? I assume 2 are turn signals but what about the third?
Thanks for your help
