HOW TO: over boost/ shift light in Dash cluster.
 

Here's a quick how to fit a shift/overboost light to your miata. stealth style.
i did this mod so i could delete my boost gauge. i use the 5th injector channel on my emanage to switch it on if boost goes too high or at my set rev point as a shift light.

i picked up a 10mm high intensity red LED today and have fitted it to the lamp holder usually used for the high beam lamp. just drill 2 holes in the back of the holder for the LED legs to come out the back AND SNAP OFF OR BEND IN THE OLD LAMP HOLDER CONTACTS.

then its a simple matter of hooking up wire from the led to your emanage (dont forget the 470 or 560 ohm resistor). +ve for the LED to ECU power and -ve to the sub injector wire.
sorry for the crappy cell phone pics, my DSLR is away being recalibrated.

Cut the high beam icon part off your warning light blind as above. re assemble and your good to go!
as you can see, my 7 year old DIY dials are crappy and need replacing...hence the cluster removal in the first place.
