ECM wire connectors

[the missing link]

I am not sure on the 2250 but on my 871 there are pins inside . The outer shell is just a plastic shell . There should be zip ties on the bottom holding it together. Or at least on my 871 .
If you pull the plug off make sure you start the plug in first and as you tighen the screw in ,you wiggle the plug the whole time . If the pins don't line up you can push the pins in on the ecm or the plug .
Remember talk to someone a whole lot smarter then me before you take my advice to serious.
