What would it take to swap my OBDII LS for a OBDI LS ECU. Can I use my wiring harness or will I have to rewire everything.
thanks
ps I did a serch and couldn't find anything.

 

You will need one of these and an obd 1 ls ecu.

 

Can you please give me more info like were I can find one of those? Does it just all hook up?

thanks

 

Most shops carry them. Its an ecu jumper harness. It runs about $250 or so. I got the pic from http://www.inlinefour.com

 

We produce some of these and have them available through a few shops in the US. http://www.C-SpeedRacing.Com, and http://www.JDMHondaparts.Com.

 

I can make the harness you need. Email me for more info.

when going from OBD-II to OBD-I or OBD-I to pre-OBD, and getting those ECU adapters, is there any other modifications needed to any other wiring?

 

When going from OBD2 (verson 1 and 2) to OBD1 there are no modifications necessary. Unless you have a GS-R and intend on keeping the dual plane intake manifold with the IAB.

When going from OBD1 to 'Pre OBD' there are wiring modifications necessary (e.g. injector resistor box, distributor, injectors, etc.).
