Look in the engine compartment for someones wizardry of wire splicing - usually will be accompanied by a mass of electrical tape covering it all. May Be around ignition coil or at the firewall. When you find the mass of tape - remove tape and post all wire colors you see and we can figure it out from there ...
try replaceing the headlight switch.
