I have installed a Sho-me LED flasher unit to my custom LED taillights on my 2005 Dodge Magnum Rt. my problem is that all 3 of my taillights are wired together so they all flash together instead of left and right wig wag. I bought a 5 pin relay and harness. And I have found the wire that links the taillights together. Now I just need some professional help on how to hook up the relay. Basically I just need it to break the contact between the taillights when powered on, then when off I need it to make contact again for my break lights to function.

86 is power

85 is ground

30 is input

87a is normally closed until power is applied to 86 and

87 is normally open until power is applied to 86.
