Dead ECU causing no spark condition 850

Has anybody out there ever seen a wiring harness on a late model 850 just give up the ghost for no apparent reason...I have ruined four ECU modules...my initial trouble was no spark (see my other "no spark" posting)..all the usual suspects did not effect the repair.....replacing the ecu did...2 days later, that replacement is also junk...can reproduce the symptoms by placing the bad ecu in another 850......it just seems unlikely that a short in the harness would affect only the ecu....there are no other symptoms other than lack of spark while cranking, no codes set, etc....any thoughts on possible culprits would be appreciated.....Thanks
