diy 1993 mazda miata alarm

1 and wire the actuators in parallel.

thanks for the quick reply!

Do I need to use diode isolate some wires like parking lights, door triggers ...etc? I see some ppl do and some dont when installing this alarm!

Only on the white if you only have 1 white output light, if 2 don't bother, if one feed to 2 x 1N5404 diodes, bars away from alarm and go to the Haz switch, to left and right indicators, only US cars use lights and I'm assuming you have a Japanese spec R/hand drive.  If r/h/drive mount the unit behind glove box, go to interior light right hand side of door contacts, fit a trunk switch to underside of lid. fit a hood switch to flat section behind headlamp.
