Looking for a schematic for a montgomery ward 500 oil heating system. Mine is all messed up Otherwise how do I figure out which wires go where. There are 3 wires from the limit switch, red(fan),blue (limit), black (low voltage spot). Oil pump 2 wires, white and black. Blower 3 wires red,white,and black. The red wires were hooked up before and some others before a friend got to it.

It is a honeywell. I guess I don't need it now since someone hooked it up already. Thanks
