Thanks Gents,

	I will check that this weekend.  I'm not sure where I got Pin 24
from but I'll use the excuse...  "To see if anyone was listening"

I didn't key in on the fact that pin 17 was mentioned, only that my
cable instructions say to use P2-24. :)

Just for completeness, here is a summary of the data connections between
the EM2 (integrated display) and EC2:

EC2 pin 7  - EM2 P2-11  Serial Data from EC2 to EM2
EC2 pin 27 - EM2 P2-24  Serial data from EM2 to EC2
EC2 pin 17 - EM2 P3-6   EFI data from EC2 to EM2
    pin 17 is also the rotor 1 primary injector signal.

For the separate display model, the connections to P2 go to the red
and white wires included with the display connector instead.
