Refurbed a 70s Cab... Need Help Wiring

[ghosty999]

This is a bit of a noob question I know... but I just refurbed this old cab with some Teal Tolex, Black hardware, gold mesh and Peavy 16ohm Speakers.

I've cut a square to put in a Marshall style mono/stereo switch on the back

I just want to make 100% I'm wiring this correctly?

Thanks!
