Electrical connector parts source?

I need a 2 prong male plug that fits the auxiliary switch connector under hood. Dealer wants $70!!!!!!!

 

2016 Volvo VNL D13. The auxiliary switch harness terminates under the hood, below the treadle valve, with a blue plug in it to seal it. I want to hook a work light into that circuit. The female plug is there, I'd like to get a male plug rather than cut and install a new connection.
Online is hit or miss due to different sizes and types.
I will try parts stores to see if I can get something that will work.

 

Thanks. I have to stop in there anyway.

$5 beats the heck out of $70!!! I got 2, in case I need to hook something up to the other auxiliary switch.

 

Well, after all that, I had the wrong connection on the truck. Went back to the dealer to get it turned on in the light module, and the mechanic told me that was the wrong connection
He showed me the right one, a single wire, and I found a connector, thanks to QUALITYTRUCK.
