Test connector location?

I am led to believe there is a 'test connector' (single contact) that when you apply +12v it will directly operate the fuel pump for troubleshooting purposes.

They infer that it's located in the middle of the engine toward the back near the firewall.

I do not see it. Can you or another user take a pix of this test connector so we know where it's located?

This is where a .jpg photo would be very helpful.

Best regards,
