[ctchme]

Hey guys,
Am trying to rewire my car, and am bein a tightarse, am using the factory relays, and dont understand the numbering system, it goes 1,2,3,4,5.
I know that 5 is ground, but cant work out what the other 4 are for. Am using it for headlights, so any help would be great

use a multimeter on until you get a continuity across 2(switch) then the other 2 should be the load.
