okay so i bought a 97 ex coupe shell and i bought a 00 d16y8 motor
i got a 00 stock ecu and i got a 00 engine harness
i took it to a shop and they said i need a 97 ecu and a 97 engine harness
is this true at all

 

No, if its a 00 engine using a 00 ecu and 00 engine harness it will work fine.

96 - 98 OBD2a

99 - 00 OBD2B is the only difference. ( U may need to get a OBD2b to OBD2A harness for the inside where the ecu is connected. ) do engine harnesses have that part i forgot?

 

Yes, you'll need a '96 -'98 EX harness, manual if its a manual, automatic if its an automatic. You didn't mention it, but you'll also need a '96 - '98 distributor, the '99 - '00s use a different smaller plug.

It doesn't work, '99 - '00 engine harness wont plug in to a '96 - '98 underdash harness.

 

If you really want you can get an OBD2B to OBD2A harness adapter, but they're not cheap...

 

i <3 my eg are all ek's like this, not plug and play like the eg's?

 

so if i just bought the adapter id be able to run with no problems?
or would i still have to buy a new distributor ?

 

anyone?

 

you'll still need to buy everything I listed above, the only thing it gets you out of buying is a '96 - '98 EX ECU which I forgot to mention in my previous post, you can probably buy an '96 - '98 ECU for less than you can get an adapter harness for anyway. You should also be able to sell that '99 - '00 EX harness btw, EX/Si engine harnesses are always hot items.

 

i got a 98 harness sitting in my garage i bought that one 1st then someone told me i needed to get a 00 harness and i bought the harness adapter for 100 bucks shipped im gonna go out and get the distributor sometime soon
but thanks for the info i couldent figure it out to save my life
thanks man
