You are right to look for help,
Dave (eirebus) is right abour the dangers also,
Look locally for an auto electrician.
Good place to start looking is call or phone your nearest truck garage and ask them who the auto electrician is and usually they will let you know,
Make sure the correct rated fuse is used as thats your protection should the appliance draw too much amps the correct fuse should do its job
