Custom Rywire Harness for 88-91 Civic/CRX with D15Z1 - $1000
 

Hello,

I have a custom-made Rywire Harness for an 88-91 Civic/CRX running a D15Z1 (Civic VX) engine.

It's made to run from the engine to a P07 ECU code free (OBDI).

This harness accommodates both EGR sensors (manifold & vacuum box).

Included is a separate jumper harness, so you can use a wide or narrow band O2 sensor (4 pin to 5 wire O2 ntk sensor adapter).

This harness is brand new and never used. I have the original receipt as well.

I bought this 7 years ago for a project that never came into fruition.

I'm located in the San Francisco Bay Area.

I'll try to post some pics in the following days.

Thank you for reading.

Is it possible to run a VX ECU with a narrowband without a code?

I personally don't have the knowledge to answer that question. Maybe someone in the forum can. As far as I know, it was custom built to run code free with a wide or narrow band sensor and a P07 ECU.
