Anyone know where the seatbelt buzzer unit is? Its driving me bananas! (11/99)
I've had my little blue baby just over a month now, and the buzzer was one of the first things I changed (the first was flash to pass). I didn't need a light on warning (I rarely use just side lights and tend to notice the main lights being open), so I just disconnected the buzzer. If you go to the miata site (http://www.miata.net/garage/buzzer.html) you can find a whole host of things that people have done to their buzzers - including a light warning. (12/99)
In addition to this, does anyone know what the buzzer looks like? Mine works intermittently, so by the Law of Murphy, it doesn't work when I'm trying to find the bloody thing! (1/00)
It's a little black box with,IIRC, a white 8pin connector on it. It's located to the left of the steering colomn. Mine didn't do anything at all...opened it up and found a resistor that had gotten so hot that the solder had melted. Resoldered it and it works fine now. You probably have the same problem. It's been over a year since I did it, but I believe the resistor was something of 180ohm. Couldn't read the colored rings anymore as all the paint had burnt off.. (1/00)
oops, forgot to mention that this is on a lhd car...don't know about rhd cars...sorry (1/00)

It's a little black box with,IIRC, a white 8pin connector on it. **Only two terminals connected though**

It's located to the left of the steering colomn **Right on RHD**

You need to connect a wire from a "live with lights on point" (Most Red wires with Black tracers - try on the backs of the ancillary switches/blanks) to the buzzer and a wire from the buzzer to the door switches - easiest point on your car is the red/white (red with white tracer) behind the interior light. (More complicated on later cars with screen rail mounteed interior lights)

The buzzer should only work one way round - if it works both ways you need a diode as well. (1/00)
I need to change it into a lights on warning buzzer instead, any help much appreciated. (1/00)
For the cost of a new buzzer, I'd just buy a new one. Total cost of the bits at Maplins is only 2-3 quid. I wired mine to the back of one of the dash switches (12V when lights are on) and to the back of the courtesy light (gnd when door open) and it works a treat. Fit a diode though, as otherwise dark current rises. (1/00)
I just fitted a buzzer and a diode between a light feed to the back of a dash switch and the switched ground on the back of the courtesy light. About 2.50 for the bits and 10 mins to fit it. (4/00)
Or you could buy one mine cost 3. Only downside is the distructions were only in German and Japanese but there was only 2 wires. One to the inferior light (needed to solder) and one in the block for the lighting near the steering wheel. Works OK (8/00)

Buy a small 12v buzzer (cost 1.50) from Maplin or a similar electronic shop and a diode rated at about 10 amps ( a lower rating will do but the 10 amp one only costs about 1) see the Maplin site for mail order.

Lift the centre console and join one wire of the buzzer to the bulb that lights the ash tray. Join the other wire to the diode. You may have to experiment to find out which side of the diode to connect to the buzzer - see below. Join the other side of the diode to one of the courtsey light swithches- if you lift part of the rear carpet and take out one switch you can easilly feed the wire through. If you have connected the diode the right way round, when you open a door with the lights on the buzzer will sound.

If the diode is connected the wrong way round the interior light will stay on all the time. (1/01)
I found it easier to connect into the back of the courtesy light on the driver's side (it just pops out and you can scotchlock to the wire) and to the illumination feed for one of the dash switches (again, these just pop out) (1/01)
