using a switch on negative wire?

[sikcavy 10+ year member]

I have a negative wire coming from my tsunami FDB1004-AGU block and it is for the leds and display on it.. The thing is when i hook up the negative wire, the leds come on because the block is getting constant power for the amp.. i am in turn going to put a switch on the negative wire with a led rocker switch but the thing is, when the switch is on and one side of the negative wire from the block is touching one side of the switch, the led on the rocker switch comes on.. but when i hook the other side of the switch to complete the circuit, the block lights up but the led in the switch goes off.. how can i make it so the led in the switch comes on when the block is on?

I would guess you have to switch the wires around in the rear of the switch. Not sure, though. I'm tired and can't think clearly

i tried that but the light dims when the block is on... it dims like quite a bit.
