sup guys. i have a 96 civic hatch dx and i want to put a b18a1 (out of a 90 teggy obd0) in it and i was wondering wat harness i need or if i can use the stock one. i have a obd0 pr4 ecu. also does any one have a wiring diagram and vacuum i can have so i can put it in. thanks guys i really need the help.

 

Go to your car with the pr4 obdo ecu and attempt to install it.

 

don't mess with the ob0 crap you actually could run you dx wiring harness belvie it or not just need a obd1 wire conversion harness and a pr4 from a obd1 or you could run a p28 chipped what ever your pref is I would stay with the stock pr4 for now. you will need a obd1 dizzy obd 2 injectors can use your dx one's once again. if you got any more questions pm me. Swaped t ls/vtec in my 97 civic and actually passed emissons in NY freaking hard to do actually has to connnect to the computers in albany at the dmv and do a all systems go. Sucks.

 

well your going to need a hydro tranny first off if you dont already have one. and i would just get the jumper and a p76 just find a dizzy and injectors from a odb1 teggy

 

Plugs for the obd2 engine harness will not except obd1 injectors. Cable tarns will work just need a hydro to cable conversion from hcp or hasport
