No crank

I own a 69 Barracuda 360 with 4 speed.

My problem is that I turn the key and nothing happens. The battery is good and I have power to the bulkhead and the starter relay. It has a new ignition switch and a new forward wiring harness.

I had the same problem last year when attempting to start the car. I took the starter off to have tested and it ended up working at the auto parts store. I re-installed and car started fine.

This year it's doing the same thing and it is frustrating. I did just install the wiring harness so not sure if that is a factor to why it will not crank.

Which harness did you install?
