FANS!!!!!!!!!!!!
what fun this has been.. the boards are full of fan questions with no fan answers.. thanx to Green_Ghost for coming through with some wiring diagrams comparing Series, parallel and Series/parallel wiring. turns out the easiest way is the best way... GO FIGURE!??
So take the ends of your fan wires and twist them together. black to black and red to red. Put somekind of connector on there. if it's just a splice then don't worry about making them different, but if you are going to put a removable connector on them. Make the positive a male and the neg a female or whatever just so you can tell them apart, and not possibly reconnect them backward in the future.
Now get your pigtail or cutoff cell charger or whatever your PS(power supply) is and put on your connectors, just remember which is + and - so you don't have to go back and do it again... You see I'm using 2 different kinds.. you'll find out why in a minute.
I decided I want a kill switch right on top of the viv for when I open and close the hood, or just for quick access for whatever reason, so I put this toggle inline (always put switches on the positive)
Now I'm ready to install it when time comes. it will be in an eggcrate box, well out of FrogBert's reach at the top front of the viv. one fan pointing at the glass, and the other at the background.
