    I'm installing a ham radio which will be turned on by ACC. I'll be installing a new radio relay that gets triggered by the ACC relay (via a fuse tap at F18). I've discussed the design in depth with other people who've done the same, so no worries there. Now where do I hang this relay so it...

    Hey all, I’m planning on a ham radio install in the MZ3 2022 sedan. I’m trying to keep a high quality install without any fuse tapping. I.e I want the install to be just like any other OEM accessory with its own fuse. 1. Can you plug in a fused cable with a blade connector in an unused fuse...

    I'm going to try and install aftermarket heated mirrors on my 22 sedan. I'm really annoyed that Canada gets this and we don't. Im further north than some parts of Canada. There is dew ón the glass almost évery morning. Years of wiping it off daily is going to get on my nerves. The mirror pops...

    It seems like ebay has cheap kits for adding heated mirrors. I'm not sure how well these will work or if they will work at all. I'm hoping there are electrical connectors sitting there connected to the defrost button that aren't connected on the US models which would make it a lot easier...

    I installed the OEM wireless charger which involved drilling a hole in my center console and all that fun. As part of the process you have to disconnect like 15 harnesses. Even after taking everything apart a second time and I can not find the plug for the SD card. I don't know if it was even...

    Cross-posted on Reddit. I have a 2015 Mazda 3 that recently had most of its driver's side front door replaced (and the area in front of the door behind the wheel, including parts of the left suspension, repaired or replaced) due to a collision. After the repairs I immediately noticed the "BSM...

    I just recently changed to NGK Iridium spark plugs part number #6510. I have them gapped at .27. I did clean my K&N Air filter with their spray and i also disconnected my battery alongside my oem intercooler and my Cobb Bypass Valve while i was replacing the spark plugs. After about a week, i...

    I really want to set up a type of launch control on my 2010 2.5. I researched an item called bee + r that basically connects to power, ground, switch, and both cables for icm to the ecu. Problem is I have no clue where the two cables are on the ecu for ignition control. So ideally I’m looking...

    Anyone experience this? Specifically with a 2011 3 GT Hatchback (2.5L) Car has 105k miles Basically, if the car is cold, it starts up fine but if I drive it a short distance, usually under a mile, turn it off for like 5-10 mins when I run into the store, it will sometimes struggle to start...

    My 2014 Mazda 3 (about 130000km), after sitting in my intermittently heated garage for a week without being started was dead. Weird, but I boosted it, and upon starting it, I noticed that all of the lights were flickering. I thought it was just because it was slowly building charge, so I put it...
  11. 2010-2013 Mazda 3 & Skyactiv How-To Guides
    I’m new to Mazda and can only do basic maintenance on most other vehicles. The other day while climbing out of the car I clipped something with my foot. After a quick search I found a wire with a chip and a light in the end of it the slide off. I was wondering what this thing does and how do I...

    Hi all, first time posting here. I'm having a bit of a complicated electrical problem with my vehicle (2012 Mazda 3 iTouring hatch, 2.0L Skyactiv, auto transmission); I'll try to explain as briefly as possible. The car is currently at the Mazda dealer, and they are having difficulty diagnosing...

    So my car has been stalling, the AC shuts off randomly, the exterior frontlights dim during driving, the ABS light comes on and I lose power steering. It comes back within seconds. If you dont know what the fuse post is, take a look at your battery's positve terminal. That black rectangle on the...

    I own a 2007 Mazda 3, about a month ago my interior lights stopped coming on when I open the door and won’t work when pressing the light buttons. When turning the key on my instrument gauge needles all spike up and then down and then back to the spots they need to be. My anti theft light doesn’t...

    I have a new 2019 Mazda 3 Sport GT and it is making a strange noise when the engine is not running. I suspect the sound is there also when the engine is running. The noise is there if I turn on the ignition but do not start the engine and after the engine is running it lasts for about 15...

    Hello, I'm trying to work through long-standing electrical problems on my Mazda 3 but don't know what to check next. 2005 Mazda 3 Sport GT - 2.3L I've had parasitic drain on my battery for a couple of years and finally decided to try to rectify it recently; I have been using a trickle charger...

    Hello, I Recently bought a 2012 m\Mazda 3 hatch and was wondering if it is possible to hook up some footwell lights that basically act the same as the interior lights at night. Ideally, they stay off during the day and when the night time running lights are on, they to come on. My last car was...
