so can i use the OBD2 ecu without jumper?

thanks for the help

 

sure if you wanna hack into your wire harness, which I wouldn't recommend..

 

You don't need any jumper, and you should not use the OBD2 ecu. Find yourself an OBD1 P72 which plugs directly into your harness and you only need to add the knock sensor and IAB wires. If you try using the OBD2 ecu you will have to face the immobilizer, crank flux sensor, and add a secondary O2 sensor. Difficult and totally pointless.

 

oh ok just try to see all options cuz the teg harness did plug right in so should i get a 92-95 EX/SI harness and a OBD1 P72 ECU?

 

lol i was posting right when you were posting but yea from the way u put it OBD1 sounds better

 

Everyone who is OBD2 is always trying to convert back to OBD1 ecu's, take advantage of being OBD1 already and not needed to buy converters or anything.
