I would also strongly suggest purchasing either a Haynes or Chilton Manual, available at most auto parts stores. It has specific information you will need incuding the Torque Specifications for each and every Bolt and Nut you will be removing. Cost is $20-$25 fo the manuals.

Let me know if this helped, or if you have additional information or questions. Feel Free to contact me at FixYa.com!

Its the electrical part of the ignition switch.. thats pretty common for a 91 Honda

There are 2 engines for 92 civics, so that can make ordering parts 'interesting" sometimes. Some websites that sell factory OEM parts have the option of using your vin for your vehicle to locate parts. The only problem there, is that OEM parts are more expensive Check out hondapartscheap site, from Southbay Honda for great diagrams of car parts. You can use your vin on their site for access to proper parts.
