Cargo Light and Reverse Light Mod
So I blacked out my 3RD brake light, and of course the cargo light is dim as ****. Ive got LED's in it, but its still not enough. I wanted to do this before, but now I reayy need it. I want the reverse lights to come on when I turn my cargo light on, but NOT the other way around, I DONT need the cargo light to come on when put in Rev. How would be the EASIEST WAY to do this? I was thinking either a relay, or a diode. If i could find the right wires under the hood, I think a diode would be the easiest, mainly because the LED's dont suck near the power, so I can mouch off the other line. Give me your thoughts

And I also plan on running an LED strip under the rail of each side of the bed, and hook it to the cargo light switch. Otta be pretty sexy i think!

The easiest way for me to look at it would be to run a relay. Say you have a relay like this:
Then hook it up like this:
86 - Cargo light
85 - Ground
30 - Reverse lights
87a - Reverse lights
87 - 12 volts
This way when the cargo switch is turned on it will send 12 volts to the reverse lights turning them on. But when the reverse lights are on it will simply pass through the relay (30 to 87a) without turning the cargo light on. You will need a Single Pull Double Throw relay like the one pictured to do this (5 terminals).
Then hook it up like this:
86 - Cargo light
85 - Ground
30 - Reverse lights
87a - Reverse lights
