[Myfirst67]

I have tail lights but no turn signals and no brake lights. where should I start my investigation? Is there a way to get a wiring chart for my 67 f100?
Thanks

start by looking at your turn signal unit in the steering column. all brake light and turn signal functions go thru there!
Wiring diagrams can be found in the tech and tutorials link at the top of the page.

I had the same problem. I needed to replace the turn sig switch it was broken. When I replaced the unit all my brake lights work fine, and I am not blowin any more fuses.
