Dilemma - to pay or not to pay?

Folks:

I had an issue with a vehicle that I could not figure out; I'm a pretty competent home mechanic and rarely take anything to a shop.
The shop where I took it spent 4 hours on the vehicle and could not find the problem either.

When I got it home, I kept plugging away and eventually traced the problem to an intermittent broken connection in a multi-plug in the harness going to the engine (not an easy find).

My question is, should I pay the shop (approx $450) for their work?

Essentially I got the vehicle back in the same condition as I left it.

As I said I rarely take a vehicle to a shop, so not sure what the etiquette is here. What would you do?

thanks
