Alrighty...So I'm doing a 97 OBD2a GSR swap into a 2000 DX Civic Hatch and I am currently working on the wiring. I'm using the original SOHC harness, but modifying the length of some of the wiring to the plugs.

Besides adding the traditional wires like the knock sensor, the VTEC oil pressure sensor and the VTEC Solenoid as all swaps require, how do you wire the 3 pin Crank Angle Sensor plug from the SOHC to the GSR's 2 pin connector? I know there's a bypass trick but I was wondering about actually making it functional instead of just ignoring it.

In Addition, since the GSR's have the secondary butterfly’s in the manifold I need to wire that to the ecu. Sound's good right?

The oxygen sensor...the SOHC has two plugs; The GSR will only use one. Which one of the two plugs do I use?

I would really appreciate the feedback guys. Thanks!

 

wont the gsr use 2 oxygen sensors? i thought only obd1 had the single o2 sensor. im running obd1 in my 97 and i used the plug from under the hood and removed the 1 in the cat

 

BUMP

The motor came out of a Del Sol with an OBD1 ECU which is what I am using.
