OK I recently bought a 1993 Civic hatchback shell. the previous owner throw in a D16z6, then i got a decent deal on a b16a2 out of a 2000 si. I have every thing figured out regarding the B16A2 swap except for the engine harness. I have researched and have found conflicting information....

There's what i think:

2000 si harness ODB 2 one piece- can't use

d16z6 harness ODB 1 connects to the shock tower - I will have to change injectors, alt, dizzy, run vtec wire from ecu and extend some wires

ODB 2 integra connects to the shock tower - injectors, alt, and dizzy are good
cost $100 to $150

so the easiest option is to buy the odb 2 integra harness

am I right?

Thank you for the help
( my first HONDA)

 

plan on a chipped p28 ecu

 

Re use your Z6 harness.

Use a OBD2 to OBD1 distributor conversion.

Use a OBD1 ECU. Stock JDM B16A ECU will work, but you'll have a 110mph speed limiter...or a chipped P28 will work. Or a OBD1 Del Sol B16A3 ECU (HA!! Good luck).

If you are using a NON chipped ECU, you need to make a 1 wire subharness for knock. And extend the IAT wires and solder the OBD2 plug onto them. The B16A2 IAT sits in the intake arm. Alternatively, you can use a ITR/CTR/OBD1 B16 intake manifold and IAT and reuse your Z6 IAT plug.

Those two connections are the only changes you'll need for your Z6 harness.

Since I'm a helpful person...I will direct you to make sure you have the right driver side mount and bracket combo.

 

Everything above is correct, however I repinned the distributor to OBD1 plugs rather than buy a conversion harness.

Make sure you don't get the IACV, IAT, and Evap control plugs mixed up or you burn up expensive *** sensors. *doh*

These two pics got me through my swap.

 

thanks for the reply's. Its really helping out

 

You'll want to reuse your Z6 injectors. For your alternator you can use any OBD1 b series alternator OR swap to an OBD2 alternator plug. You'll have a plug by the crank which is the CKF sensor, ignore that.
