Still fighting with wiring.
I found out that I have OBD I engine.
Is there anyone who made M52B28 OBD I ('95 or '96)
to OBD I 318ti '95 ?
Engine cranks but no spark and no fuel, and I'm running out
of options.
I've made horrible mistake connectingo G117 ground to battery
positive. I've reversed it but could I fried my ECU or some fuse?

maybe there're some differences in x20, or I need to add UNL (I cannot
find one in my car or the engine harness) ? ECM an Fuel pumo relays are not
kicking in, there is only low voltage on them (2 or 6V).
