Help! Going to make a harness for my head lights but do not want to splice into the factory harness. Where can I get the plug that would plug into the factory harness and the plugs that plug into the bulb itself. Everything else is easy pickins but those two items. Actually the ones that plug into the bulbs could be taken at the junkyards but it is the connector that looks like the back of a lamp that is the one I can't find. Help please!
