Side Winker Install

Zoom Engineering side winkers - Mmmmmmmm.

Your Shopping List


  • A pair of winkers! - Lots of places to get a set of stock blinkers. Might I suggest a set from the NC? They use the same hole pattern and come with chrome surrounds. I bought a set of Zoom Engineering side winkers from Rev9.
  • Blue painter's tape - This will protect your paint during the insane fender cutting process. It's very important.
  • A method of cutting your fender - If you use the Zoom winkers, I'd suggest a hole saw designed for cutting metal. Otherwise, a Dremel with the reinforced cutting wheels should be your tool of choice.
  • ~Ten feet of 20-22 gauge wire in two colors. I used blue and black since I had that around.
  • Four vampire taps for your chosen gauge of wire.
  • A nice crimping tool, a wire stripper, and wire cutters.
  • Electrical tape

Frequently Asked Questions


  • Where do I get some winkers?
    Every market except the US got these fancy side/fender winker/blinker/marker lights on all previous generations of Miatas. That's right, PREVIOUS. Go to your dealer and get a set from the current car, the NC Miata. The special edition ones came with chrome rings. Very darn spiffy. If you'd like the Zoom or RS Products winkers, check out Rev9, linked at the top of this page.

  • How do I wire them?
    These blinkers/winkers should only blink. They should NOT glow with your parking lights. I mean, they can if you really want, but the stock wiring in the EU and JDM markets have them only blinking, not glowing. On all NA Miatas, you're looking for a green wire going to your front turn signals. It'll have a colored stripe, but the main color is green. And the ground wire is black like you'd expect. Tap into these.

  • A hole saw? Really?
    Yeah! They make hole saws that are designed to cut through metal. I got one at Home Depot next to the ones that only cut through wood. It called for a low operation speed of 125 rpm for cutting steel. My drill isn't that accurate, so I just set it to low and drilled carefully. I did this because of the shape of the Zoom markers. I'd have rather used my Dremel, but a round hole was called for.

  • Where do I put them?
    This is THE diagram, found on many Miata message boards throughout the intarwebz. I hope the original creator doesn't mind me posting it here. Remember to measure a half dozen times before cutting your precious fenders.

    Preliminary Work
    Say hello to Optimus Prime
    Say hello to Optimus Prime. Since Shockwave got to help with my gauge face install, I figured I'd give the big guy a crack at some side winkers.

    Besides getting out your toys and camera and tools, you need to do a little printing. Print out the above winker location diagram (or maybe just this WHOLE how-to) and a couple copies of the following template.


    Winker template
    I created this template by overlaying some artwork on a scanned gasket. That's right, there's a gasket that comes with the stock winkers. If you've got a set of stockers, there's probably a rubber gasket at the bottom. You can remove this and hold it up to a printout to verify that this template is the correct size. Also, here's a PDF version. Who knows if Firefox will print the above image at the correct DPI, but the chances of Acrobat/CutePDF printing it correctly are very good.


    Use jackstands! And a small robot.
    Since you need to peel back your fender liner to get behind your fender for the wiring (Do it now! You'll need a slot-head screwdriver.), you might as well jack up the car. Room to work is nice. And Prime reminds you to always use jack stands.


    Use safety glasses.
    Yes, a whole image to remind you to use safety glasses. Your vision is important.


    Hole saw
    This is what my metal-cutting hole saw looks like. I had to buy a mandrel for it, but the whole setup was pretty cheap compared to a unibit which wouldn't have been big enough anyway. 38mm is what I used for the Zoom blinker. That's juuuuust a little oversized. You'll see what I did with that extra room shortly.


    Measuring and Test Cutting
    Measure twice, take pix, let Prime measure, and then cut.
    Optimus Prime always measures twice and cuts once. Except for when he just wants to blap some Decepticon scum.

    Since I have most of a Miata worth of spare parts, I decided to take a spare fender and cut a hole in it. Such drama over 30 seconds worth of drilling, but SERIOUSLY, it worried me. So here's my preliminary cutting. Note the 5 layers of painter's tape used?


    Pilot hole drilled
    The hole saw mandrel has a fairly large bit. I wanted a slightly smaller and more accurate pilot hole. You'll want one too.


    Hole drilled!
    Whew! Seriously, about 30 seconds of drilling at a low speed got me all the way through. Our Miatas don't have very thick fenders. I used WD-40 to keep the hole saw lubricated and re-sprayed two or three times.


    Test hole cut!
    And there's the test hole in the spare fender all cut and happy. No surrounding paint was damaged. It was really not a bad method of hacking up a precious fender.


    Installing Stock Blinkers
    Stock winker install
    A very nice guy called butterflywings on ClubRoadster.net let me re-post his excellent stock winker install here on my site. Thanks, Sherman!!! Notice the template he made out of cardboard. Very nice work.


    tiny Dremel cuts
    THIS is why I asked Sherman to use his photos. Look at those cuts! That's nice work. It's not difficult to make a lot of little cuts like this. Just remind yourself that you have all the time in the world. A little care will get you a perfect stock-sized hole.


    stock hole finished
    After removing the extra metal, that hole is just perfect. I originally planned to do this to my car, but my Zoom blinkers are slightly oversized for this hole. After cutting, I would have had to cut a little more, so I went for the hole saw.

    Zoom Engineering Specific Mods
    Little dinky retaining rings
    The Zoom winkers are beautiful, but they expect you to rely on very weak double sided tape to hold them to your fenders. I was NOT having any of that. I quickly bent up these little retaining rings out of some copper. They're not pretty, but they grip the body of the Zoom marker really tight and grab onto the back side of the fender a bit. If the winkers get loose, these should hold them long enough for me to notice.


    better mounting tape
    In addition to the little rings, I ripped off the weak Zoom Engineering tape and replaced it with Scotch 5 pound mounting tape. This stuff is pretty strong. 5 pound is about as strong as double sided tape comes. Prime was happy to help. He approved of the tape color.


    All taped up
    There we are! I taped the barrel as well as the lip. Now the winker juuuuust barely fits in my 38mm hole with the extra tape. The tape also helps hold the little retaining rings in place on the back of the fender.


    Zoom Blinker Install!
    Pilot hole drilled
    Finally, we're up to my actual winker install. Seems like a lot of pix and text for such a small mod. My pilot hole completely covered my center mark drawn over the tape, making it look like I didn't make one. Don't be fooled, I spent many minutes getting that point in just the right spot.


    hole drilled
    The hole came out perfect. No damage. In fact, all three hole-saw-holes I drilled came out perfect. The hole saw might make a pretty horrible noise, but it worked great. Sharka was very happy to have no fender damage. Bucky, reflected in the door, looks afraid.


    wiring time
    Wiring is almost an afterthought to this project. You just need a nice long run of wire (an arm span, about 5 feet, is what I went with) and a couple vampire taps. I tapped in right behind the front signal bulb on either side and ran the wiring inside the engine bay. There's a nice square hole on either side of the inner fender directly above the side blinker.


    Inside the fender
    Once I verified I had the wiring right, I shoved the winker in the hole and applied my little retaining clips. They're probably not necessary, that tape is REALLY strong, but they make me feel a little more secure about the expensive markers not falling out.


    Final shot - winkers installed
    Ta-da! The winkers are installed. I hope this incredibly long how-to helps give others the tools and confidence they need to hack up their own fenders. It really is an easy project and so worth the effort.


    ...and that's it.
