Thought I asked this yesterday, but I don't see that message, so here
we go again. Sorry if it becomes a duplicate.

Just want to know where to connect up a tachometer on my 93 Taurus
3.0L automatic.

Ground is a no brainer :-) but where can I find the other point to
connect it up? I am sure its near the ignition module, but I don't see
any obvious connector waiting for the tach.

Much obliged for any assistance.

John

Hook the signal input lead to the switched side of the ignition coil.

If there are conflicting/confusing instructions, just pretend the car has
an old-timey points distributor. The same should apply to any engine that
has a single ignition coil.
