HA,
Single big Phillips head bolt secures junction block to firewall...into a threaded nut captive in the firewall...so no need to worry about a nut...but there should be a wire with a ring terminal on that bolt...its the chassis connection for fan (we just recently figured that out on the forum)...clean this ring terminal and associated connections well and assure bolt is snug for good fan electrical supply and operation.
...from memory, I believe ends are single flares at junction block and double at wheel components, but inspect and match the replacements exactly before installing...ask for British threads when replacing lines individually.
Good Hunting!
