Default Wiring guru needed

I bought some LED cubes, I also bought a harness with a relay and fuse already made and also had a cheap switch on it.. I have a switch panel and want to wire it to my led rocker switch. I cut off the old switch and there are 3 wires. Blue, red and white. Does anyone have any tricks to tell what wires are for the load, ground and power on the switch? Pictures below.

It's difficult to tell by color alone because many manufacturers have different color codes.

But you should be able to tell by looking at the back of the relay. Ideally, the back of the relay has pins on it that we need to see. You can then compare it to a schematic of a similar relay such as the one below to know what pin is what, and this will tell you what wire is what:

If you know the brand led lights email the maker and ask what color wire is what.
