I have a 94 hatch and i am putting in a 99 d16y8 and im running a p28 ecu

can i use my old harness or do i need to get a obd2 harness?

 

use the stock harness, modify necessary plugs (dizzy, injectors, altenator, etc) to plug into obd2 motor. or u can just use ur stock harness and swap the obd2 parts on the motor with obd1 parts. the obd2 harness wont plug into you car w/o lots of mods

 

so when i purchase my y8, i dont need to purchase the harness ?

just use my stock one?

 

just keep your stock harness, and buy an obd2 - obd1 conversion harness to make things easy.

 

where can i get the conversion harness?
what company makes them?

WTF???? He has a 94 obd1 hatch. He is putting in an odb2 motor. Where exactly does this harness adaptor go??? OBD2 civic harness is one complete harness to the ecu. OBD1 civic has the shock tower plugs.

Reuse old distributor, injectors, and harness. Add VTEC wires if needed. Let here rip.

 

do you know of any step by step instructions?

my friend told me that i can use a y8 distributor

 

What exact model is your hatch? Is the new motor going in from a auto or 5speed? Let me know I will will try to point you in the right direction. Its not going to be hard at all. That swap is pretty straight forward.

 

i have a 94 civic DX hatchback 5 speed (d15b7, not like you need to know)

puttin in a 2000 civic ex d16y8 5 speed with a P28 (obd1 ecu)

and Skunk2 sells odb2 engine to odb1 ecu harnesses for $283.00

ohhh whoops. i read that wrong then. yeah, ignore what i said. hope you're familiar with wire cutters and crimps cuz you're going to be doing a lot of that.

 

The o2 sensor thats on the stock motor, is it a one wire, or a 4 wire.
