Help with ECM

Does any one have a schematic of the three connectors on the ECM? the Gray White and Black? My problem is the jeep wont start sometime or just dies while driving. If I wiggle the Black Connector it starts and runs fine, if I wiggle it again it dies. Would you think the problem is in the ECM or the black Connector? The only thing I noticed when I got the donor connector from the JK the two little tabs you squeeze are missing on the one in the jeep. Oh this is a 97 ZJ.

Chances are the ECM itself is ok, it's just the loose connector that's causing problems. Hit it with some spray electronics cleaner and then snug it down with a zip tie
