I have a replacement circuit board, but we are not sure on how it needs to be wired right. We do not have the money to pay someone else to come and do it and if we had a wiring diagram for it, it could be done ourselves. Would greatly appreciate it if someone could help me find one... Thank you!

Its pretty simple, if you have the correct exact match to the old board,, just pull the old one loose away from where its mounted replace with new board,, now one wire,, one plug at a time start removing and putting it into the new board,, if you would like you can draw a hand drawn picture and label each wire and where it goes. Some people even take a close-up digital picture of the old board before beginning the task

,, hope this helps

Can you give us a list of the terminals on the new board, and a list of the terminals on the old board? (if boards are different in any way) Clear pictures would help for sure.
