Yes you do need the Diode. It allows the voltage from the headlight relay to pass thru it and power the running lights, but not allow power to go the other way. Without the diode, the voltage can pass the other way and turn on your headlights during the day when only the running lights are supposed to be on.

ryanh2 - Go to Radio Shack and get a #1N4007 Diode or anything close for about $.50 and a few small pieces of 16 gauge wire.
