The change was made in 97 to gold plate pins (sensor/harness).
94/96 is silver color pins (tin plate?). At first the missmatch in metals
does not make a big deal. Its over the long haul than it does. If a
conductive grease is used on the install its not an issue.
The grey sensor has a smaller target vrs the black sensor.
This was the bandaid to close the +/-% error of the sensor.
When you get the new sensor get the measurements (length) from
the mounting face to the tip of the sensor, also the size if the tip (od).
Maybe some photo's? Compare it to the old grey one.
The biggest problem with a cps install is "NO ONE" sets/checks the "AIR GAP".
Everyone just tosses it in. Its the main reason you see/feel a change in how the motor runs. IH even has a shim kit if you need to open the gap.
On another note.
I have allways wanted to change the cps circuit to a cat5 sheilded wiring system.
Just never had the time to test to see if its worth the effort.

Its the heart of the ign system.
I use .025 to .030 as paydirt cold.
It will grow some being its mounted in the alumn cover.
How much? I dont know. I never remeasured hot.
To get the measurement i check gear runout and cam thrust first.
Its important in setting the gap. The working window of cam thrust
is .004 to .012
IIRC i think swamps has done some extensive testing with the gaps.
Only use die grease on the seal of the connection not the pins.
For the pins use a conductive grease.

Well this thread is very encouraging. Could you point us in the direction of more detailed directions, cause I have no idea what you just typed. I'm gonna pull my cps and shim it, maybe it'll fix my problem.

But, having the correct gap, like Bill is talking about, will ensure a correct reading on the timing wheel.
I never had really thought of it before, or being an issue on our trucks. I would really like to know more.
And Bill, why would you want to use Cat 5 for the wiring? Its just a twisted pair of wires, the wire is twisted to prevent cross talk between wires, not to prevent other interference. They do make shielded twisted pairs, that is what you should be looking for.

What?! I have no idea what the gear runout and cam thrust is. haha.
And yes, bill is right on the grease. people always want to use dielectric for conductive grease. There are purposes to both. =)

International Stuff pictures from cars photos on webshots
Supposed to be some tech sheet from IH about the gap settings in here.
Webshots is painfully slow for me.

Picture pictures from cars photos on webshots is the link to the pic Andy is talking about. i'm going to see if my buddy knows anything about setting said air gap. if not i'm going to IH to see if anyone there can show me. LoL.

IIRC its was .010 change in lenght from the black vrs grey sensor.
I would have to look it up. I would like to see the lenght of the
so called "new and improved sensor". OTC and SPX make a tool.
Its expensive, $350.00
http://international.spx.com/content...SE4414-10A.pdf
In 97 IH started to shim every T444e on the assembly line.
The PSD version did not get this done. Its why you have never seen
a PSD with cps shims! Over 2million units made.

You might be able to rig a dial indicator into an old dead CPS ...Or if you are savvy enough, make one out of a sleeve welded to some flat stock , & a screw to hold the indicator
