I have just installed my Thinkware H100 dashcam in my CX-5 GS. It was really easy with a MirrorTap MTX cable. The only downside is that the cable cost a small fortune to import to Canada with the shipping and the exchange rate.
The basic steps were:
Here's the end result - the extra wire goes to my GPS accessory for the dashcam.
Update:
The basic steps were:
- Use a voltmeter to determine that the outside of the power connector barrel was the -ve lead and the inside of the barrel was the +ve lead. The power plug fit my dashcam even tho it sticks out a little bit.
- Attach 3M Dual Lock tape to the windshield mount. I found it on Amazon. This tape basically is like velcro that you attach to the dashcam and to the windshield.
- Insert the leads of the MirrorTap into the HomeLink mirror. I found that the purple wire on the passenger side is the +ve lead and the black wire on the driver side is the -ve lead. This provides 12V DC switched power. I could not get a decent picture of this as the phone went into macro mode.
- Turn on the car in Accessory mode with the dashcam plugged in. It worked the first time.
- Turn off the car.
- Attach the dashcam mount to the windshield. I held it while I counted to 100 to ensure that the mount adhered properly.
- Attach the dashcam to the mount.
- Turn on the car again, It worked perfectly.
- Tidy up the wires. I had not done that in this picture yet.
Here's the end result - the extra wire goes to my GPS accessory for the dashcam.
Update:
- I ended up having to splice my existing barrel connector onto the MirrorTap. The stock connector just did not fit well enough - you can see that in the picture I took. My splicing is a bit of an ugly job but electrical tape hides the worst of it.
- Purple is the switched +12 V connection. Blue is the always on. This is for the 2018 CX-5 GS. You could use the blue connection if you have a parking mode - my ThinkWare H100 does. You will be at risk of draining the battery; however.
