Proper reverb tank connection?

[Indie]

I just received accutronics reverb tank for my twin reverb
Can anybody tell me what is proprer connectinon between amp and unit?

Should I plug reverb tank output to amp reverb output connector....
I mean is it ok to plugg out to out and input to input...?

I am confused cause here I have two different coloured ends of cables.......one side is red other is gray

There is a correct signal flow you must follow, but don't worry about it--it simply won't work if connected backward, and you won't break it.
