Almost certainly yes, *BUT* I don't know if the tach driver card (what you
are calling 'daughter card') is specific to the number of engine
cylinders. It defies logic, but car design sometimes does, and so it may
be. A quick check of the parts catalogue would answer this question.
Below I have pasted the info I have that I found elsewhere which says that
the tach signal is for a 4 cylinder even when the engine is a v6. Also the
cluster would not work directly because the speedometer on the sundance is
cable driven and on the dynasty it is electronic.
"1 The 1.6 and 2.0 liter engines are
manufactured by Mitsubishi, and are also
used in vehicles produced under their name.
The same connection configuration applies.
2 When using pin 43 of the SBEC (Single
Board Engine Controller) as the tach
connection point, the NUMBER OF
CYLINDERS selector on the tachometer is
set to the 4 cylinder position regardless of
the number of cylinders in the engine!
3 In some applications, there may not be a wire
connected to pin 43 of the Single Board
Engine Controller, however the tach signal is
available at this pin.

I have encountered the rev limiter while in park (holding the engine WOT in
park makes a nice sound with the 3.3 and is also a good way to check the
motor mounts IMHO) but have not hit it with the vehicle in gear so I
wondered if it was enabled at all in drive.
I don't NEED a tach with an auto tranny but I WANT one. Always was curiuos
what the actual curb idle and cranking speeds are. Besides my sister's
Mercury Sable 3.0 has the AXOD-E trans and it has a factory tach (Damn
fords)
Yes, it is. On a car with a 3-speed auto, you can easily hit the rev
limiter while the car's in motion: Just shift to "1" and start
accelerating. The A604 (and family) will do its best to avoid letting the
engine reach redline, which means it WILL upshift 1-2 and 2-3 even if you
place the shifter in "L" (the shift points are simply delayed). 3rd gear
is 1:1 (direct drive), so calculate your tire circumference, check your
final-drive ratio and do the maths to figure out how fast you'd have to be
driving in 3rd to hit the rev limiter. (Hint: driving that fast will get
your car impounded and your ass jailed)
The tach you're looking at won't tell you that. It does not register
during engine cranking, and the calibrations are not sufficient
to tell you what the idle speed is to any useful degree of precision. All
you'll be able to tell is that it's something less than 1,000 RPM.

Hi...
Time for my silly question... :)
If 3rd is 1:1 - then what's OD (3 in a circle) ?
And while I'm at it, at about what speed, driving old man style on
the flat prairies should I expect it to lock up?
Reason I ask that is I've never felt it do so... with previous
GM products I sure did. First few times a little unsettling - a
bit of a change in attitude, a noticable slowing of the engine,
and if you gently touched the brake pedal it vibrated just a bit
under my foot.
Now I plan to try it gently and watch the tach, but...
Take care.

A604 ratios are:
1st: 2.84
2nd: 1.57
3rd: 1.00
4th: 0.69
Torque converter lockup is available in 2nd, 3rd and 4th.
There is no "3 in a circle" on any of the A604/41TE/42LE quadrants I've
ever seen; they're all P R N [D] 3 L.
There is no single lockup speed. See above; lockup can occur in 2nd, 3rd
or 4th and at variable road speeds and loads.
When everything's working correctly, the A604 (etc.) lockup is very, very
difficult to detect. I suppose that's one reason you want a tachometer!

Erm...the cluster will not work directly because it won't bolt into the
dash.
No idea why you think this is relevant. There were no 1.6 or 2.0 litre
Sundances or Dynasties.
OK -- I would believe this out of hand if it came from a Chrysler source.
If it's just some random guy's statement, I'd need more proof (or to try
it myself).
<snip a bunch more inapplicable crap about 1.6 and 2.0 litre engines that
don't exist in Sundances or Dynasties>
