1971 LeSabre not starting after brake booster change

Like the title says.

 

Tried to post a video but it made it a picture

 

Turn it on, everything lights up and just get a click.

 

Try jumping the solenoid to see if its faulty?

 

So I tested the battery and it's fine. I'm gonna change the starter since I have a new one anyway. Here's hoping.

 

New starter is in. Still giving the click but not engaging the starter.

 

Clean the battery terminals 1st.

I’m just trying to connect the dots between booster and no start. That booster is right above the firewall electrical connector and the main wiring harness is nearby. Any chance that wires got tugged on or brake fluid washed down the firewall connector?

 

Took the battery out and had it tested, it's perfect. Everything on the battery is clean.

 

Brake fluid is not an issue. Wondering if a wire got messed up.

 

It ended up being a combination of problems. The old starter died and there was a purple connector that needed to be on the back of the brake pedal switch. She started right up.
