Ok this is a really good question...

I have a 91 Honda CRX putting in a B16A OBD0 engine that has been upgraded to OBD1 P28 ecu with hondata etc....

I have a donor connectors from obd0 ecu and obd1 harness.
So far wired up the adapter harness no real problems.....

Hasports wiring off there web site lists
-Alternator FR signal on OBD0 as B14 to OBD1 D9
and alternator control as blank

Is this a error or for some reason

If you look up the wiring OBD0
B5 is alternaotr FR signal
B14 is alternator control
OBD1
D9 is alternator FR signal
A16 is alternator control

Only thing is that the 94 Honda Civic OBD1 P28 has ELD electronic Load detector
And the OBD1 ecu has a input from this to D10

Has anyone done this conversion
thanks
