Not done this mod but think it looks a good idea? All other cars in the family have this facility as standard and I find it good to use. Great on motorways when changing between lanes. Interesting that it works with LEDās so no balance resistors needed? Not a bad price overall. Thanks for the link.
My other car has the ātap turnā facility and I miss it when Iām in the MX5. Ā I may be completely wrong, but looking at the links provided it seems there are two ways to achieve this; either third party replacement flasher units or āwire-inā modules. Ā Itās also commented that this may be a standard feature on other current Mazdas. Ā I wonder if the feature is simply built in to the flasher relay itself on the other models which have the feature. Ā So, substituting a flasher relay from one of these may achieve the effect?? Being a āstandardā part, may be less expensive?
Current Mazda3 on some models has the option to turn on a 3-Flash or not as part of the Settings/Vehicle/Turn menu, also volume of the click. The flashing is under software control from the RBCM (Rear Body Control Module) computer. Long gone is the clicky relay. I would expect the ND is the same.
NC still has a clicky box Flasher Control Module just above the bonnet release handle which might be possible to mod to include a Stay-On delay, if there is not a flasher with it already available for the other older Mazda cars or for US or Continent.

Thanks Richard. Ā Appreciated. Ā I realise much more vehicle control is being moved to software control which is why i wondered if the feature was built into a flasher relay or not. Ā It seems not. Ā Seems daft, but lack of this feature really bugs me when I change between cars. Ā Iāll look at the flasher relay options suggested so far, unless someone on here can suggest a suitable alternative relay.
Iāve had a look inside the NC Flasher unit. It is physically different to those used on NA and NB. Seven pins are used in a ten pin connector with key. Writing on it is F151 66 830 and more usefully 3211-229-320. It claims to be 90cycles per minute.
It uses the Temic U2044B IC as the heart of the system to drive the two relays, and follows exactly the application circuit on the Data Sheet for the chip. This means that the effective input impedance of each half of the circuit as seen by the stalk switch is approximately 1KOhm to ground.
Now if someone bodged a 4700uF 25V capacitor to ground on each input wire after the switch then there would be a hold of about 4 to 6 seconds for maybe six to eight flash cycles. Unfortunately, the initial surge charging up the capacitor would probably very rapidly shorten the life of the switch on the stalk. Adding a 100Ohm resistor in series with the capacitor to limit the surge into the capacitor would reduce the hold time slightly, say four to six flash cycles, and the switch might last a bit longer⦠but I donāt recommend this at all.
IMHO the only sensible solution is to intercept the lines from the switch and add a pulse extender using a couple of transistors, easy enough to do, but my life is too short to bother making one when there is a commercial unit available to do the job.
Iām in the process of changing the majority of my bulbs to LED but have had no success in finding a suitable plug-in flasher unit. Iāve spoken to Mazda who advise that the MK4 LED flasher unit will not fit the Mk3 and agree that the Tapturn, which is LED friendly, would be the best option.
So⦠Just ordered it, Iāll update when itās fitted.
Bought one fitted it (5mins) and works a treat. It takes a little getting used to just tapping, but on motorway or quick overtake itās great and the 4 way flashers are changeable if needs be. I also have the third brake light flashing (another unit), which I have been told by those following me really draws their attention.
The āTap-turnā arrived about ten mins ago and is now fitted and working Ā Ā I spent more time looking for theĀ flasher unit than fitting it, but a quick course in Advanced Yoga would have been useful for laying on my back in the footwell whilst holding my torch in my mouth and wiggling the retaining clip out of the unit.
I bought the Tap-turn primarily for the LED compatibility, so my newly fitted (and much brighter) LED indicator bulbs now flash regularly instead of hyper-flashing.Ā
