why dont u ring ems
im pretty sure they have a good help desk section
they can advise u what parts to run
and get them to fax a wiring diagram if u dont have one
makes life alot easier
if u have the right ems for the engine
it should have 2 triggers coming out to 2 modules and then to 2 coils
u said u got the engine with the 3sgte
was it running is the ems for that engine
usually when u order an ems they modify it internally to suit the engine so check that out
maybe do some ringing round first to see
better to spend bit more getting the right parts
less hassles in long run and get better performance out of it
