Need wiring diagram

[EGOR46 at aol.com]

Would anyone happen to have the ignition circuit wiring diagram for a 93 
90CS?  I've been working off and on for the past three weeks trying to get 
spark in my 90.  I have an identical working 90 so I have changed out the 
ECM, coil, ignition module, engine speed sensor, crank sensor, and cam 
position sensor.  I have triple checked all engine compartment connections 
and fuses including under the dash and am at a loss as to where to look next. 
 With a wiring diagram perhaps I can do a systematic elimination process to 
find the problem.  Thanks
