1986 420SEL - won't start after dash re-installed

[simonshearer]

I drove it into my garage, removed the dash, repaired the wood paneling, re-installed the dash and now it will not start.

Cranks strongly; battery 12.7V.

What might I have disturbed under the dash area that would cause this. I didn't touch anything under the hood. What about connectors to the main instrument panel?

I did remove the steering wheel and airbag, and re-installed same.

Thanks. Help would be most appreciated! I'm stumped!
