We just get a little irritated when someone shows up and starts demanding info when it's obvious they haven't used the search function or even Google to try to help themself, and then cops an attitude when given an answer that, while completely accurate and potentially even helpful, requires a small modicum of work on their part.
But since I'm about to leave for an AutoX and I need some good Karma right now...
Assuming your MSD box has four wires (red, black, white, yellow) then the wiring is:
Red = +12 when key is on
Black = GND
White = CKP in from CAS
Yellow = CKP out to ECU
I didn't have this data squirreled away in some secret members-only archive, I just used Google. Took about three minutes.
Assuming a 1.6 car (you didn't specify) then the CKP wire is a white wire at position 2E on the ECU.
Have we serviced your needs adequately?
