Don, W3FPR posted the information after my sig a couple weeks ago. I
used it myself to remote a KPA/KAT100 into an EC2. I didn't save all the
header info for the post, but it shouldn't be too hard to find it in the
archives.
You didn't say whether you are including the KAT100 in the enclosure. I
did and everything goes together fairly simply once you sketch it all
out on paper first.

"The KAT100-2 contains all the connectors for plugging in the
KPA100(except for the speaker cable), connect the base K2 RF (the ANT1
jack ifthe KAT2 is included) to the RF IN jack on the KAT100 and connect
theKAT100 control cable between the KIO2 option in the base K2 and the
DB-9jack on either the KAT100 or the KAT100.If you do not wish to use
the KAT100, it is just as easy. Drill a holein the bottom of of the EC2
enclosure (right rear area) to mount a BNCconnector. Solder an E620012
header to the back of the BNC jack toprovide a connector to plug the
KPA100 input coax into - you will have 2of those parts with the KPA100
kit - they are normally used at K2 RF P3and P6. Make certain the
orientation is correct, the center conductorof the input coax must
connect to the BNC jack center conductor.Download the KAT100 manual from
Elecraft and build the control cablethat is shown in that manual.Connect
the base K2 RF output to the BNC jack on the EC2 enclosure andthe
control cable to the DB-9 connector on the KPA100. The connectorwith 2
cables must be plugged into the KIO2 if you use the connection tothe
computer.Just one additional caution - do all the KPA100 alignment
andcalibration and checkout while connected directly to the base K2 (no
QRPtop cover), and check out the KAT100 using that same
configuration.Once everything works in that configuration, move the
KPA100 to the EC2and put the QRP top cover on the K2 - connect the 2
cables between theK2 and EC2 and it should work OK." [W3FPR]

I was just contemplating ordering the components to do this project
and tried to find the referenced KK7P site
(http://www.kk7p.com/k2kpa100.html) but it seems to have "gone away".
Did anyone save the instructions?
