EF vs. DA ECUs
I was wondering if the female connection sides are the same
On a OBD0 88-91 USDM Civic/Crx Sohc ECU
And on a OBD0 90-91 USDM Integra ECU
?
If they are the same, then it should be possible to convert a 90-91 Integra to OBD1.
So far I havent found anyone that has done the conversion for a 90-91 Integra. I remember reading someone sells the harnesses for the EF conversion. Would that harness do any good for a DA? The goal is to run a P28, P30, or P72 (whatever is less of a pain in a OBD0 DA).

by female side do you mean the wire harness side that plugs into the ecu? they are the same, yes. a 90-91 ecu will plug right into a 88-91 wiring harness.

an OBD1 car. you need to get an adapter harness
and go from non OBD to OBD1. blown90hatch on this board makes them...
and then u need an OBD1 ECU....hth
oh u need a set of saturated injectors too,..good luck!
