You can connect it at the ECU. The Tach Signal Colors for each year are:
1990-93: Yellow with Blue Stripe (Position 1H)
1994-97: Black with White Stripe (Position 1H)
1999-05: Green with Orange Stripe (Position 2K)
Connect the green wire to the brown striped black wire.
Blue wire is for a tach I believe
The tach should connect to the distributor.
how do you run the wire for the power windows on a 91 Mazda miata
look on the distributor cap, there is a slot marked "tach", connect the hot wire there and ground the other wire
there is a white almost tanish looking solid color wire on the group of wires that plug into the guage cluster use a quick connect to connect the signal wire from the tach to the white wire on the guage cluster
Since the coil is in the distributor, simply hook the tach 'trigger' wire to the out put on the side of the distributor cap marked 'tach'.
pin 48 on the pcm connecter is tach signal connect to your green wire from tach
Yes.
Its EASY! just connect the (usually green) wire to the negative post on the coil. Hook up the power wires and the illumination wire and ground for the tach wire and ur done its easy!
attach the green wire to the negative terminal of the coil. if its an hei, it will have a terminal that says tach on it.
on my tach, the green wire connects to the neg on the ign coil pack
