I can't seem to find a part number for the block-off plate I need to complete my oil injection delete. I have a 40TLRX. I thought to look at the parts list for similar-year three cylinder C40 motors, but I can't seem to find the part listed on any diagrams. I might end up fabricating one if they're expensive.

By the way, what do I need to do to keep the "alarm" happy? I could pull my multimeter out and figure it out, but I figured one of y'all has reasoned through this already.
