I am trying to save this totaled Rc F , it spun two main bearings due to the engine oil cooler busted during a wreck. It’s going back together now but while installing the engine ecm I noticed some corrosion and tried to brush it off using the wrong tools. I’m not sure if the bottom left pin on both plugs is supposed to be missing or if I broke them.

Can someone let me know what the pins connection went to if they are broken?
Will it run without them, I’m real close to a test run?

Any recommendations on a good place to get it fixed?
