Wiring gurus (do we have any?)-

I'm putting an LED lighting system on my truck bed and running power through a relay and switch mounted in the cab... I noticed that when I turn power on to the lights I get a voltage spike on the low current 12v that includes a toggle switch. This is the same 12v that sends a remote on signal to my stereo amp (the blue wire)... it causes a loud crackle over the speakers, which I'm guessing is a voltage spike to the amp. In any event, I read that you can fix this by wiring in a diode across the relay control (85/86 terminals)... I bought a bunch of 1amp and 3amp diodes. How do I install those? There is a red end and a white end on the diodes, which goes to which terminal on the relay? Help a brother out! thanks
