I need to know what to do, i am swapping a complete jdm d15b into my 1990 civic hatchback si, i am putting in the p08 ecu, i bought the obd0-obd1 conversion harness from jdmshit.com, i am completely lost on what to do for the wiring, can somebody please help, ive been asking for help and noone replies, and i need to know if i need to use a 4-wire o2 sensor? thank you for your help

 

Not to act all smart, but: Did you call JDMshit.com?

Or maybe if you PM "Newman", he knows about that stuff.

 

jdmshit gave some thing, but its not enough info, and whats newmans id?

 

Newman

I think he is affiliated with JDMshit.com... he is very helpfull

I would search for all threads created by him first... there is a very good one, about obd1 conversions.

 

the p08 ECU as well as JDM D15B VTEC use a single 1 wire o2 sensor, unlike the usdm p28 and D16Z6.
