i ordered the part that is supposed to be the replacement for Whirlpool 4448874. i believe it is 8186024 AP2929035

problem is not that the wires dont match up. i did get the instructions for the "extra" piece. but no instruction for the main board. the main plug on the oven is 8 prong, there is no 8 prong on the new board. even if it is the right one and the what way do i shift the plug in order for it to work?

customer service has said it is right, they did offer me to return it and that may need to happen but i have to fix this oven. its for a single mom

how do i wire it up? is it right?

Thanks so much
Brent
