Okay, for running lights it will be a bit easier as you only need a single relay. First thing is to look at the directions and be sure that the red wire is positive, and the black is negative, have seen that reversed a few times.
So, if the black wires are ground, the simple solution would be to crimp a ring terminal on each one and simply drill a hole in a grounded body part nearby and use a screw into clean metal. Then spray some paint over it to slow rust down. That leaves the red wires to deal with. For those you can use a crimp and seal butt connector on the one side farthest from the fuse box to attach a longer red wire to go across to the other light. Now to install a relay to control them. Go to the fuse box and find a place to tap constant power from. Run a wire with an inline fuse (look at the amp rating of both lights combined to determine fuse size) down toward the lights. Get a 12-volt relay (common as dirt 4 pin Bosch style will do the job) Now for the wiring. You have the power for the lights from the fuse box. You have the red wire that will power the lights. If you want to test them just touch those wires together and you can see how they will look. Now you need two other wires, one will be the ground for the relay and the other will be the control wire for the relay. For the ground you just need a piece of black wire with a ring terminal on one end that gets attached like you did the other grounds, then mount the relay where you like so that the power and ground leads reach it.
Cut the power lead and crimp on a connector to fit the relay, push that connector onto terminal 87 on the relay.
Cut the ground wire and crimp a connector onto it, then push that onto terminal 85 on the relay.
Next take a piece of the red wire like you used to run the new wire to connect the lights. Connect the two lights and the red wire together and run that red wire up to the relay, add a connector and attach that wire to terminal 30 on the relay.
Now for the last wire, the one that will turn the lights on with the running lights. For this one goes to the front marker light or the side marker light and find the brown wire. That is the power feed for the running lights. Now for the hard part, you need to tap that wire, the easy way is to cut it and use the butt connectors like you did for the red wire, just add a brown wire to one side so that you can run to the relay.
Run that wire up to the relay and add the connector and put it onto terminal 86 on the relay.
OK if you have it wired correctly turning on the marker lights should now turn on the halos.
See the attached for a diagram. Any questions just ask.
