I have a 2007 Honda Fit GE6 model... When I look for wiring diagrams, it tells me GE6 only starts from 2008! Can someone assist? My Fit has absolutely no power except for the hooter and hazard lights - the battery is fine

 

If your Honda Fit is a 2007 model but the wiring diagrams only show from 2008, it could be that the wiring for your car is a little different, but should still be pretty close. If you’ve already checked the battery, it might be worth looking at the fuses or relays for things like the ignition and power distribution. Sometimes these can get fried and cause just this kind of issue where only the basics work. If you're comfortable, try tracing the wiring for any obvious loose connections

 

First check the 80A fuse in the under the hood fuse box, then the 50A fuse. Those cover many of your issues. Would also check ignition fuses and the Electronic Current Sensor. My current sensor has been replace 2x Im at 170k mi. The relay partiallly melted and I had a hard time removing it, but it was obviously at least one of my issues every 85k miles or so.
