Mazda MX-5: Rear View Camera Installation Update (Rewire!)

My eBay “Made in China” reverse camera paired with the Pioneer  AVH-X2700BS has been rewired today and is in perfect working order… YaY!

So I initially installed my backup camera back in January when I tackled the touch-screen head unit install. It was freaking cold and freezing but being on a high from the Southeast Asia MX-5 Road Trip I decided to go ahead and do it because the guys really inspired me at all three places I visited: Thailand, Malaysia and Singapore, everyone wanted to show their’s, and everyone’s looked different.

The issue was, my cheap eBay china-made camera came with the wrong wire. It was missing the bit that connects to a wire on a head unit labeled “Reverse Input” which is meant to be spliced into the reverse light in the tail light to activate the display on the head unit.

I went ahead and ordered the $3 wire (and another $2 bux shipping from China) in March, it arrived in April but I’ve been putting the install away until the weather got warm and pleasant. Today was exactly such a day. Armed with the correct video cable that has the extra power wire built in, I tackled the re-routing job this time starting from the trunk, rear of the car, and working my way up forward along the sidewall and into the dash, the back of the unit. It was far easier to do now than the initial install!

First I melted away the soldering I did originally (I built a far bigger blob than was required) added an additional wire and re-soldered it in place making things nice and neat. Then I wrapped the whole thing with a good amount of electrical tape and worked my way forward threading the cable from the trunk, along the side of the rear quarter panel (having to open the PRHT top to do it) down along the side sill, under the glove box and into the area behind the unit. Easy Peasy!

Here’s some photos of the re-route:

This little bugger with the extra wire (besides video) for power to the “Reverse Input” on the back of the head unit harness was all that was needed to make things work perfectly!

I also took the opportunity to clean out the area on the back of the tail lights. The way the car is designed water drains out from the hole between the trunk and the quarter panels under the tail light and behind the rear bumper. The back of the tail lights were filthy!

So I went ahead and cleaned them out… very easy job.

Also cleaned the dust build up on the bumper surrounding the light.

To shake things down I took the car for a spin on a ride to Walmart to pick up another jug of Pennzoil full synthetic 5W20 which slickdeals alerted me was on sale for under $8 bux! There’s a $10 manufacturer rebate from Pennzoil and another $5 rebate from another app that works with Walmart. Everything worked well. Except for the damn rattle that comes from the hood around the speedometer cluster. I added a bit of electrical tape to dampen the rattle but it’s still there. So when I got home I stuck a little bit more electrical tape, hopefully it works better this time.

The reverse image comes on as soon as I put the car in reverse, and unlike last time, it turns off when I shift out of “R”!  Perfect!

I bought three more of these backup cameras to take as gifts on my trip to Australia and New Zealand. And my buddy Guy who requested one of these from me installed his camera under the trunk lid which is what I initially wanted to do. But after a little bit more thought I think I’ll keep it exactly where it is now.

Mazda MX-5: Project BOSEctomy, replacing the BOSE Sound System on my Miata

I would like to have a touch screen head unit in my Miata. This means a potential BOSEctomy replacing the current BOSE sound system with something more interesting. My requirements are a double din 6+ inch touch screen with Navigation if it is feasible, but as price is a major factor I don’t see myself spending $700+ on a head unit.

So far, I’ve taken advantage of the Black Friday sales to purchase a Metra 99-7506 double din mounting kit which replaces the BOSE bezel giving the aftermarket stereo a factory look. I also got the ASWC-1 Steering Wheel Controls wiring harness necessary for the volume buttons and such to work with the new head unit. Thanks to a great deal from Jet.com I got both of these items shipped to me for $30 bux or so which is really reasonable considering the list price on the ASWC is $46 and the Metra bezel $26.

Now I must decide on a head unit and more importantly on what to do with the BOSE speakers which at this time make some buzzing sound whenever it is wet or cold outside. I’m sure there’s water getting on them causing this problem and I would really like to fix it as I’ve been driving around with the radio OFF lately to avoid doing more damage. Ideally I’d like to keep the BOSE speakers but maybe use some foam speaker baskets to protect them for the water.

I could certainly use a lot of help with this project. If anyone has done this kind of audio mod on their MX-5 in North Jersey I’d be happy to provide unlimited beer supply for any assistance in helping me install my new system.

Stay tuned for more as I make progress with this project. I’d like to have my touch screen installed by the summer time.
