Accidentally disconnected the wire circled in blue this pic. Now my glow plug won’t light on dashboard and car won’t start. Couple of questions

1. what is it? Is it a ground?
2. Any tricks on getting the bolt back on its very tight in there.

Would not thought it would affect glow plugs but may have earthed and blown a fuse when you tried to start it.
