head light flasher with drl

I have a 2011 Honda accord I'm trying to install a head light flasher from Sho me with positive output but I keep getting feed back.(the drls keep flashing even though the flasher is off).I tried putting diodes in line but they had no effect.A friend of mine said some thing about using a few relays to separate the bulbs from the cars computer when operating but I'm not sure how to wire it in with the flasher. Your response would be greatly appreciated.

You will need to cut the factory wires powering the headlights. Wire it as follows: Factory switch side 87a, Flasher 87 Headlight 30 ground (-) 85 Sho-me switched +12v constant 86 When the flasher is turned on the relay will open 87a and close 87 to head light. If drivers head light wire loops across to passenger light you will only need one relay to flash lights together. To alternate lights will need to have individual flasher feeds to 87 on 2 relays one on each headlight.
