And with that another crisis was averted.

You gonna practice repinning on the donor plugs?

No, I miss-spoke.

What I planned on doing is to use the pigtails and re-pin them.

Then cut off the connectors from my cars cluster and wire it up by matching the pin colors from one pigtail to the other.

But... I just realized I got these pigtails from a 2001. That has different pins than 03-05 so I won't be doing it that way.

Just use the donor plug to practice taking the pins out then repin your factory plugs, once you get started it's not that hard. You will need a donor pin or 2 so it helps to have those plugs anyway.

Thanks Tom, we'll do.

Man how did I miss this! I've been wanting a tach and 140 speedo for my '97 Turbo Vic so badly!

Definately going to pursue this very soon!

Ok. Finally started on my cluster swap today. Reading through this thread I found out that I wired up the Tach Adapter wrong. I wired it up to a single coil instead of the whole inline coil wiring, so that will have to be addressed before I continue to much more. It's at least a good thing that I used bullet connectors, so reconnecting the cut coil wire is easy.

One thing I don't understand is how the spark is distributed.

According to this diagram of Derek's, the inline power feed splices power to each coil and obviously it pulses 8 times per revolution.

But how are these pulses "routed", for a lack of a better term, to each coil in the correct sequence? Is there an ignition module somewhere that controls this?

Are you talking about the feed for the tachometer?

The way it was explained to me was find the common wire on all 8 coils, then follow the harness they all join into and splice into that common wire later in the loom.

Do not leave a temporary connector on there, fix the wire so there is less chance for problems(like corrosion) later on.

So I'm so [censored] confused now.

I rewired my Tach Adapter, the correct way this time, checked my pins and connections, and still have no function out of the Tach.

I don't know why the Tach has no function at all. Everything else on the cluster works...

Can anyone offer any advise? I'm completely stumped on this one...

Any life out of the tach at all? This is interesting.

Not a single sign of life.

I have power to the pins, and the tach adapter is providing a signal, but still no worky. Not even a twitch of the tach needle.

is the needle pushed in to far? if it is pushed on to far it will get stuck. just something easy to check
