Mazda MX-5: A118C B40 Pro Dash Cam Installed

Good news! I’ve finally installed my dash cam.

I ordered a $66 Chinese made A118C or B40 Pro sold by a slew of sellers on eBay which arrived within a week from an LA shipping address instead of waiting 30 days for one to arrive from China. It came in a genetic looking box, with genetic looking parts, along with genetic looking hard-wiring cable.

The install process was pretty straight forward even though I’ve never done anything like this before. I unscrewed a few hex bolts holding the header in place and got access to where I wanted the wire to sit, sticking out directly above the dash cam on the windshield:

I routed it along the A-pillar down to the dash, and threaded it further down to the kick panel by the driver’s door where the fuse box is located. I used an add-a-circuit I also bought on eBay to complete my install. Crimped the wires in place, plugged in 15A+3A fuses for the camera, and was pretty much done.

Was pretty impressed how quick and easy the install was. And most importantly everything seems to work as expected, and there’s no loose wiring hanging off anywhere, which is great. A professional finish.

Since the install I’ve driven around for a few days now and am pretty impressed with the video quality. I wanted to move the dash cam up and place it higher so it’s less visible from the outside.

I’ve shared some videos from the dash cam on facebook, so check them out there. No point in uploading them to YouTube as the video quality gets absolutely destroyed. Hopefully I never have to use any of the footage off the camera for anything insurance related. But I’m looking forward to getting some nice cruising footage from the next Miata get together, which is coming up this week.

PS. I took the opportunity to do a side by side comparison between the A118C B40 Pro and my GoPro Hero 3+ they’re pretty similar in size:
