I'm having trouble getting these wired correctly. I am trying to get two flashers on the front of the lightbar and two on the back. I have a code 3 mx7000. relays 'click' when power goes to them. Lights work when I put power directly to them. I'm not sure how to test these other than to listen for the relays. The grey wires run to the lights i'm trying to flash. Black is grounded to the lightbar and the white and orange wires went to the 6 pin connector. Any help would be appreciated..
