Ae there Schematics to replace the switch, it got popped off from the leads and I don't know where the leads go to on the switch back I got 4 leads and 4 colored wires. Which go where?

Is this your part http://www.huskypowerwasher.com/productphotos/meci80243.jpg. If so when you buy an OEM part from Husky it comes with directions

Connect the black and white to the 1A and 2A (on side) then connect the gray and tan to the 1B and 2B, Black to 1A and Tan to 1B

Just bought an on/off switch from Husky (FNA Group). No instructions. Different from picture.
