For the record:

1996 CV oil pressure gauge, engine unit (sender): D4AZ-9278-A
(Motorcraft SW-1311)
1996 CV Oil pressure gauge, instrument panel unit: F6AZ-10883-
BA

This from the 1996 passenger car parts book-part #'s subject to supercession.

Strike that first item. The correct engine unit is E9SZ-9278-A or Motorcraft SW-2220. The SW-1311 is for vehicles with the electronic cluster.

Hmm,

The an on-line search yelds two different 1996 "temp gauge" options.

1995 returns one.

Any thoughts on what one to order for my 2001?

i just installed '97 CVPI cluster in my '96,(had to swap out all the guages, long story...) and would like to do this mod, however my '96 cluster doesn't have a resistor like dRock's does (his circuit is yellow, both mine are red...), nor does it have one on the back of the gauge. does that matter? will it still work using my '96 gauge? i'm thinking there may have been a difference, as dRock's car is an LS, and mine's a GS....

No, probably a build date change.

What is the build date on your '96 cluster?
Here's mine:

it's pretty illegible.....
what i can pick up is 22 may and it's either 1995 or 1996.....

here's what i can make out
GRAND MARQUIS EM114 200 KPH
F6MF-10849-BB
22 MAY 199-

that's the best i can make out. just barely.

ok. i think i'm just going to find another oil pres. gauge at the wreckers with those p/n's.....my only question is what kind of wiring is required to hook up that sending unit after i install it on the engine??

Just a general question. What years have interchangeable (non-LX) clusters?

1995-2002
2003-2007? (my guess)

LX clusters also interchange so long as they are analog and not optional digital.

1992.5-1994 (1992 as well but incorrect shift patter is printed on speedo) cv for cv and gmq for gmq (different dashes)
1995-1997 cv/gmq
1998-2002 cv/gmq
2003-2005 cv/gmq


The speedo head itself (not entire cluster) will swap 95-02 and it appears 03-05 as well. CVPI use 140mph head

I would assume 1996, which means the external resistor delete was a mid-year change

The Motorcraft SW-2220 is just a normally open pressure switch, whenever the oil pressure gets to a certain level, it closes. That is used with the "fake" gauge and the "real" gauge with the resistor.

If your original sending unit looks like a Motorcraft SW-2220, it has a threaded stud coming out of the top that the wire connects to, you shouldn't have to make any modifications to the wiring at all.

On the newer cars, Ford changed the sending unit connector, in that case, you have to either change the connector or build an adapter.
