The wire should be fine after you upgrade it to a thicker gauge. The reason it warms up is because it is too small. This is how people cause electrical fires in their house. They put in a 20 or 25 amp fuse into a circuit that is wired for only 15 amp service so that they can plug two or more things into the plug. In theory the fuse will not blow now because it will take the current, but the wire isn't rated for supplying that much current to the load, so the wire heats up and eventually will break down or heat up enough that the wire will cause the insulation and surrounding area of the wire to catch fire. So with that said you will have to upgrade that wire. It is also like compressed air. If you compress air and force it into a big pipe the big pipe will not get as warm as forcing compressed air into a smaller pipe. You are restricting the pressure, thus increasing the flow and the smaller pipe gets hot. The bigger one will not because the flow is not restricted. In all honesty the relays will not take much power to run, but the lights do, you figure you have the two headlights which take lots of power to run, then you have all the other parking lights on top of that. It is alot of current to run all of these lights at the same time.
