The answer yes.
Now going by your info under your username, you have a 2000 Civic Sedan ... right? If so, this is the "correct" way to go about switching to Power Mirrors on there:
- Get a Floor Harness off a Powered Mirror 99-00 Civic Sedan
- Get the Door Harnesses off a Powered Mirror 99-00 Civic Sedan (just the front two)
- Get the Power Mirrors off a Powered Mirror 96-00 Civic Sedan
- Get the 20A Fuse & Relay for the Power Mirrors off a Powered Mirror 96-00 Civic Sedan
Now, that will allow you to have Powered Mirrors, but if you go a bit further you can convert the entire thing to Power. Meaning Power Windows and Locks as well. If you want to do that, then in addition to the list above you will also need the following:
- Get the Door Harnesses off a Powered Mirror 99-00 Civic Sedan (from all 4 doors)
- Get Power Window Regulators (from all 4 doors) off a Powered Option 96-00 Civic Sedan
- Get Door Panels w/ Switches (from all 4 doors) off a Powered Option 96-00 Civic Sedan
- Get Door Lock Actuators (from all 4 doors) off a Powered Option 96-00 Civic Sedan
- Get Door Lock Control Box off a Powered Option 99-00 Civic Sedan
- Get the other two 20A Fuses for the Power Windows and Door Locks off a Powered Option 96-00 Civic Sedan
I believe that is it, if IIRC ... I might be missing one or two things, the list is off the top of my head and I just woke up from a nap, lol.
Now, that list is to have it all OEM Honda and all like it was Factory. If you only want Power Mirrors I'm sure you can hack it by using a relay, extending some wires and what not, but good luck figuring it all out ... Regardless you'll have to get the Powered Mirrors off a 96-00 Civic Sedan that offered it as you cannot use your Manual Mirrors.
PS. Pay attention to the year ranges I specified for each part, its crucial you do not mix them up. All electrical parts (harnesses, control box, etc) have to be from a 99-00 Civic Sedan. All other things (actuators, regulators, relay, etc) can be off any 96-00 Civic Sedan. I specified 96-00 Civic Sedan for the Door Panels and Switches, but I'm not sure if they differ from 96-98 to 99-00, so research before you go buy them or just get them off a 99-00 Civic Sedan to be sure. Also, notice how all parts are off a Civic Sedan and not from a Civic Hatch or Coupe, the reason being you cannot use parts from a Hatch or Coupe - they are completely different.
