i personally would NOT mess with the obd2 to obd1 conversion and 5 spd conversion on that accord unless you are getting it for nothing. the hassle will not be worth it unless you really want to build a race car.

it would be cheaper, easier and smarter to pick up a 94-95 accord that is 5 spd already.


just to make apoint the VIN will tell you if the car was built as an auto or 5 spd.
Very good point, I did not even take into consideration the obd differences. Even still, there are conversion haness' which play the intermediate between the ECU and the cars harness which would still make this a plug and play deal... check hasport

i am aware of the harness on the ecu.

but that does not alter the fact that there is a lot of rewiring to be done on the engine harness.

i ahve done multiple mixed obd swaps as well as several auto to 5 spd conversions.

the obd conversion process is always a pain in the ass even knowing exactly what needs to be done. alaso dont forget about wiring in the injector resistor box (thats always fun to try and explain how to accomplish to a first time swapper).

since the car is not yet purchase or obtained, i am suggesting an easier alternative than spending the extra money to get parts into a more valuable car.

overall it would be easier, cheaper and faser to go find a 95 5 spd accord....the car is cheaper since its older, but there are still a lot of great looking ones out there, the car will already be 5 spd and obd1. for a first time hybrid swap manual to auto AND obd2 to obd1 is a LOT to bite off.

for someone who is experienced though it could be a great thing to get the accord for cheap and do all the work....a lot depends on your time, money and most importantly experience.
i myself would not do it though i have done 8 swaps in teh past 14 months (4 more to come in the next few months as well).

Again, very good point. I like a challenge so I would probably go for it because every challenge is a learning experience which will make you smarter and more informed in the end.

I will admit though that I've never done and obd swap but with the complete wire harness'(engine bay) and obd adapter harnes (at the ecu) I think it would be a fun challenge to take on with not too much of a headache. Basically if you've got an obd1 motor and ecu and you get the proper wire harness conversions then the only thing that is different is the subharness that runs between the bay through the firewall and into the cab right? Wouldn't you basically be converting the obdII car into an obdI car by putting in the obdI motor and ecu?

I know that is the case if you put an obdI motor and ecu in an obd car. You are then doing the reverse and converting an obd car into obdI.. and I know hasport has the conversion harness' for this.

Now if you are doing all of the wire conversions yourself then yes it would truly be a pain in the ars. But if you get the proper conversion harness' from hasport then it should be plug and play.

Just my .02.

well hasport makes nothing for accords.
and event hen i wont trust a shop that isnt local to modify a harness for me ( i already got a place racing harness that i tossed).
its not alal that harad it just take attention to detail and the ability to do tedious things....and did i say attention to detail? the time spent looking at 2 diff wiring harnesses and making all the stuff needed work is often more than many people can do.

Very true! A real deal service manual helps too. I didn't have one in the beginning that's why I chose hasport to do my harness.

I got my conversion harness for the h22 in my 5G civic done by hasport because at the time I didn't want to chance anything. I sent them the harness for the civic and the prelude and they did their thing. When I got it back, it looked better than what I sent them. They were really detailed and lookin good. Everything plugged up just fine and more importantly worked just fine. I had to run three wires through the firewall for the EGR, knock sensor, and IAB but they provided me the wires with the connector on the engine bay end and the pins on the other end that plugged right in to the proper pins on the ecu connectors.

Overall I was very pleased with hasport, they really know their shiat. Now place racing, that's another story. I called them up before going with hasport and they were telling me that they didn't need either of my harness for the core and that they would just make it up and send it to me for $275; $25 cheaper than hasport who does require both cores. Whether the guy knew what he was talking about or not is a mystery to me... I got a bad vibe and decided on hasport instead.
