Need some mod advice

[Beano1169]

I just recently bought a led system off a fellow reefer. I have never moded anything electrical before; however this new light system is a plug and play I just need some help with the process in gutting out the old lights and placing new lights in the hood.
I have a jbj 12 gallon DX and the new LED lights are an old 14gallon DIY from Martin at modular Leds, there is a dimmer switch and all the goodies. I was curious if anyone has found step by step instructions with changing over the lighting systems.
Much appreciated for the help thanks to all who can help me out, I can’t find a thing on Google. Perhaps not searching properly.
