need help to convert OBDO to OBD1?!

Ok, motor is in on my D16Z6 swap (90 civic sedan), now I need help wirring the ECU. I want to use a p28 ECU. I think I heard I need to make a jumper harness from the p28 to my LX Sedan harness. Any info, hot to's???

i would recommend buying a harness, some dude on honda-tech.com sells em, post a msg there and hell respond i think its $180us shipped

yeah..give blown90hatch a pm on honda-tech...I think that's still his username...

or, ifyou're more adventurous..here's a how-to on wiring it up yourself... http://www.geocities.com/kurtsi_on/page8.html

i got mine from a guy named Jason ([email protected]). $150 shipped. i have sent several people (some from here) to him who were also happy.

yeah..that's the same guy... ;)

YUp JASON Is the MAN!!!!!!

Great... thanks for the help. I'll hit him up.... wish me luck!!!

if you use the p28 you'll need the d16z6 dizzy. what intake mani are you using? with the "jumper harness" all you need to do is extend 8 wires.

4 wires to o2 sensor
1 wire to knock sensor
1 wire to vtec
1 wire to check engine light (for ecu error codes)
1- i can't remeber :(

no mods to your dx harness. extend the wires and the rest is plug n' play :D makes things real easy

I'm using the Z6 Dizzy & intake manifold.

Well I can use either, I have a A6 right now, but i have he Z6 intake that came with my motor. So all i have to do is extend those 8 wires from the jumper to the places? I heard the obd-0 injectors will not work with the p-28 or do i not even need to worry about this?

which intake do u recommend using ?

I would use the z6.
