Default d15b in 89 ef

im in the process of putting the d15b in the hatch and i have a couple of questions....

1. i have an 95 harness (vx i think) cant remember but it is vtec ready and i have a p06 ecu the real question is is it plug and play.
can i rip out the std harness and install that one and rewire the cluster.

and 2. any info or links anyone have that is useful for me

thanks

If you already have the si harness on the car and working then you'll have to either buy some obd0->obd1 conversion harnesses or do the wiring yourself. If you still have the dx harness on your case then you'll have to look into doing mpfi conversion first.

the 95 harness won't plug up to your sub harness
best way is to get jumper harnesses for OBD0 -> ODB1 for the dizzy and ECU you can always go back that way. rywire sells some

95 harness will not plug and play
90-91 Si harness will not plug and play
You will need to use your original harness and add the additional wires in order to run the engine. You will need a obd 0-obd 1 conversion harness, p28 ecu, TD-42U distributor, 4 wire 02 sensor and resistor box.

i have a p08 ecu right now and i am tring to find the correct pinout for it. so i can wire up my conversion harness. i pulled apart an old 89 std ecu and pulled the plus out to solder. i think i got it but making sure.

I bought my harness through boomslang fabrications. It is a OBD0 to OBD1 with DPFI to MPFI. The only thing you need is a 4 wire o2 sensor. Saved me tons of hassle in my opinion.

i got a few questions.

1. i used the si engine harness and kept the std harness in th e chassis. will this work correctly or not.

2. i made my own conversion harness and all the wires doesnt have a space.

3. i have the p08 ecu and i was told that a 1 wire o2 will work.

and does anybody have some good wiring schematic for the 89 and the d15b where i can wire it myself
