What all do I need to make the EGR work in a 95 civic SI. I'm trying to get everything worked out before the motor goes in.

 

Either use a GSR ecu and forget about it or make sure the wire exists in which ever harness you choose to use. I got a redbull can and cut it and traced the stock gasket for the EGR, and used it with no ports. That way it doesnt flow exhaust to the intake but it also doesnt throw a code.

 

This is for the H22 thats going in my civ. I have the sensor and most of the hoses but the EGR box is missing.
