In Kawasaki ex250, can use newer ECU (10 pins) in older configuration (8 pins)? the older ones are hard to find...

Need to find the older unit. What makes you think it needs replacing?

simply, the unit on my 1991 250 is damaged. no spark on one cylinder. sometimes when I tap it gently, starts working for a short period of time. I already checked connections, and unfortunately only after replacing affected coil, I tapped the igniter and discovered the the issue.
Since old ones are hard to find, I was thinking of using newer one with different # of pins ( socket size looks the same) .

Also they don't last forever. 6 months ago I replaced one with similar problem, however, affecting both cylinders

ECU's are around aftermarket but it took me a while to find one for an 86 ZL600 I was working on....but I don't remember where I found it.
