The solenoids usually have 2 thick wire connections (probably red) - one from the battery and one to the starter motor. It will also likely have 2 thin wire connections - one from the ignition switch and one to earth. There could also be more than one wire connected to these terminals. The solenoid is usually held onto the machine with 2 bolts. Get the new solenoid first, then replace the connections like for like - but disconnect the battery first.
