im a swap a b16a obd2 into a eg coupe. right now it has a d16z6 can i use the same harness or do i need a jumper. also can i use the d16 ecu or it wont be as good. or can i just get the whole harness and put it in.

the other thing is does the shift linkage fit on the b16 or does it need a different one.

 

you CAN use the stock harness but there are some things thatt need to be wired in.
and u have to get si shift linkage, the d series is too weak

you can also get an obd2 gsr harness and plug in a obd1 b16 ecu

it works!

 

cool bumpbump i

 

what has to be wired in do i need jumpers or not. cuz im a get the b16 ecu

 

U will need an OBD1 to OBD2 jumper, or U can run an OBD1 P72 or a Chipped P28.

 

ok

 

pm bump for night

 

bump to the freakin top

 

You can use the same harness. You will need a different shift linkage.

Knock sensor will need to be wired in (if using a stock P30 or P72), as well there are some connector differences to sort out, more on this later.

Its not weak, it just doesn't fit. You can use both a '94 - '01 integra linkage, or a '99 - '00 Civic Si linkage.

Yes you can

If you decide to run an OBD2 ECU with a jumper harness. (bad idea IMO) Use a JDM OBD2 ECU, USDM OBD2 ECUs will be looking for sensors that aren't on there, including a fuel tank pressure sensor that can only really be taken care of by swapping the fuel tank. Also, you can run a P30, which honestly should have been the obvious choice seeing as how its the correct ECU for the engine. Both the P72 (GS-R ECU) and the P28 ('92 - '95 EX/Si ECU) need to be chipped correctly to run the engine properly.

Now, onto the connector issues I mentioned earlier. The connectors for the distributor, alternator and injectors all need to be addressed. There are about 3 ways to do this, some are better than others.

Method 1
-Cut OBD2 connectors off a junk harness and splice them onto the OBD1 harness.
-Very crude, but it does work fine.

Method 2
-Reuse your original wiring harness
-Reuse your D16Z6 injectors
-Swap the voltage regulator out of the old D-series alternator into the B-series alternator.
-Swap the CYP/CKP/TDC sensor from the old D-series distributor into the B-series distributor housing.
-No real downside to this method other than you no longer have a complete D16Z6 swap to sell.

Method 3
-Use a '96 - '99 Integra (you can use an '00 - '01 harness but you will need to wire in the tach signal wire), or '96 - '97 Del Sol Vtec engine harness, run the vtec wiring if using an RS/LS/GS harness. If using a GS-R, ITR or Del Sol Vtec harness the whole thing is plug and play.
-Method 3 is arguably the best way to do this swap, the only downsides being having to purchase another engine harness, and the availability of said harness.

 

so if i get a gsr or a si or del sol harness it will be a plugg and play

 

yes, except for the Si harness, the OBD2 Si's ('99 - '00 Si EM1) use a completely incompatible 1 piece harness. Again to reiterate what I said in my previous post '96 - '99 GS-R, ITR and '96 - '97 Del Sol Vtec are all 100% plug and play.
