i got an ef9. im puttin a sohc vtec obd1 i got the jumper harness i nedd help with wireing the jumper harness i need steb by step literature and diagrams if possible thanks

 

don't those come with the wiring harness....the wiring is cake.....you onle have to wire in like 9 wires and they, 4 are o2, 1 vtec selenoid,1 for vtec pressure, 2 for a switch to check codes.......don't worry about the knock sensor or the secondary runners one for a b18c

 

gnar kill is right. Its only a couple wires. It would not be a bad idea if you can get a copy of the wiring diagram for a 92-95 civic and also for a 88-91 civic SI so you can trace all the wires. Since your running a sohc vtec engine you only have to connect 6 wires. Did you get a 4 wire oxygen sensor?? If not, you can still run your car with the oxygen sensor that is in your car, but it will throw a check engine light. It wont harm anything. If your running your 1 wire oxygen sensor, then you only need to connect 3 wires (oxygen sensor signal, vtec pressure and vtec solenoid)

 

.do i use ths obd1 eg wireing harness or the one in my blown motor?

 

like the obdi distribuitor plug end the vtech selenoid plug riight?
