99 502, the stock manifolds have a mount for the ecu, but my cmi's do not, any ideas???

Just screw it to the transom behind the distributor. You have to make sure and run the ground wire from the module to to the module bracket and then to a ground source.
The case must be grounded or you won't get you any spark.

I presume that is a 502 mpi you got ? ? I just did a manifold switch too with the fuel press regulator and new breather per the advice I got here.. did you do the same mods ?
I won't be testing ours for another few weeks yet but will you let us know how yours goes ?

I did the ecu instead of the fuel pressure regulator, I'll keep you posted
