- Mon Mar 25, 2013 7:46 am #329383 Hi,

Ive tried to do as much research on this topic as i can, but im still a bit lost with all the wiring..

I have a JDM EG4 - Carb that im going to install the ITR setup into. (front cut -- i want to use the ecu the motor came with - P73)

so basically.. carburetor to OBD2

im aware that the harness wont be a plug and play into the fuse boxes so what will i need to do?

just fyi my parts list is :

ITR harness - obd2
P73 ecu
EK hatch fuel lines
EK hatch fuel tank
b16 fuel pump
ITR Motor complete, hubs, shafts, linkage, tranny, engine mounts etc

- Mon Mar 25, 2013 2:06 pm #329389 I think that converting from OBD1 to OBD2 is only making extra headaches for you when it comes to wiring. What about using a chipped OBD1 ecu?

- Mon Mar 25, 2013 2:22 pm #329391 unfortunately a p28 or similar ecu is hard to come by this side of the world, ill look at importing 1.. it will be the simplest way for sure it seems.

Thanks

so the carb harness thats in the car currently will work?? or will i need to source a obd1 harness to go with the ecu?

- Mon Mar 25, 2013 3:27 pm #329401 If you're going to chip a P28 to use tuning software, you can start with a P05, P06 or P28 I believe. I'm not a a genius in this category - I'd do the research

- Tue Mar 26, 2013 12:37 pm #329460 I'd imagine you probably need a new harness. Just seems like your carb'd harness would be missing way to many plugs.

- Tue Mar 26, 2013 5:56 pm #329470 Yeah i have the same feeling ok ill be hitting up the scrapyard for an obd1 engine and dash harness, and ill import a obd1 chipped ecu. thanks guys

- Wed Mar 27, 2013 6:38 am #329507 there was a sticky on this some where.

i would just do to your local salvage and pull the main harness from a car that was MPFI and go from there. and get all the fuel return lines and etc.. or buy one thats wrecked and use it as a donor car.

i know for sure there is a write up on d series. org.

I might be in luck on a obd1 harness, going to check it out this weekend.

Then i could get this : http://www.rywire.com/catalog/obd1-to-o ... -p-12.html

and ill be able to use the p73 ecu in the meantime

Will start a build thread next week
