  • Where to find the turn signal flasher relay

    • The flasher unit is integrated into the MICU unit located inside the under dash fuse box.

      If your turn signal lever is set to signal position you will get quite a bit of clicking and snapping coming from the column when turning the steering wheel during your turn.

      Check in under hood box, Fuse #10 (10 amp)

  • Where is the alarm fuse?

  • Where is the parklight relay? I have brake lights working, everything lighting except my park lights, checked all the fuse but they’re all good

    • It is also possible that the problem is not in relays or fuses, but in the lighting system itself or in its individual elements.

  • 2010 honda civic horn relay location ?

  • Is there any fuse for rear right wheel speed sensor? Because I can’t see any voltage in the connector.

  • What fuse should i remove to disable vehicle while traveling long term? Leaving keys with relative who reconnects battery and drives uninsured. Just want to shut down vehicle from starting without affecting ECU. Thanks

    #30 Ignition Coil Relay (under hood relay)?

    #23 Starter Signal (interior fuse box)?

  • I’ve got a question I recently bought a 2007 Honda civic ex coupe 1.8 vtec 8th gen. with a broke rod on number 4 cylinder shopped around for a few months to get a great deal on replacement engine that being said the only engine that is compatible with my car has to have the extra same vin digit in my case my vin starts with 2H sorry for not getting to the point ill get to that in a minute ok engine was local pick up only found on FB market place anywho 2 hour trip just to get it man said that engine vin Infact started with 2H keep in mind year of my car is 07 engine that I bought was out of a 2012 lx 4 door everything looks exactly the same as mine make a short story long I swapped engines got everything plugged in wired up ok my car will crank no start ive.checked everything to do with ecm pgm fi pcm even had on a obd2 scanner only code popped up was the crankshaft position sensor put new sensor on same.thing did I buy wrong engine is my engine compatible or would there be something else I’m on over looking any help will be greatly appreciated
