the assimilator mounts on a spring that is attacht to the left rear coil mount bolt.
the rectifier mounts on the left top side cover mounting bracket from the rear. the stud on it is used as one of the bolts for that bracket.
the blue MC2 capacitor mounts on the rear fender bracket to frame bolt on the left. this bracket is the one that is visable in the battery tray at the rear plate from the main backbone to the rear hoop.
hope this helps
DON'T DO IT! These archaic mechanical devices are extremely shock sensitive. It is a wonder they survive even with the spring. If you take apart a dead one you'll see what I mean. The INOA Tech Digest has a schematic for making a solid state version, but I could never get mine to work (I'm obviously not an electronics tech!). I bought a unit from RGM which is solid state, but is wired differently. Seems to last much longer (3 years now).
