whats up every one, my friend and me are doing a h2b swap in his dc. I have never swap a h22 in any car,im B and k lover my question is what wiring harness do we use. we got a obd1 jdm h22 or the obd 1 dc harness thanks!

 

Personally I'd use the DC harness. You have to add wires for the butterflies.

 

Yup, use your existing harness, then add wires.
A11 - EGR Control Solenoid
A17 - IAB Solenoid (secondary butterfly) Signal
A19 - Intake Control Solenoid Valve
D12 - EGR Valve Lift Sensor Signal
D19 - EGR Valve Lift Sensor 5V (shares with MAP sensor)

 

the car is a GSR so it has butterflys

 

Yeah but the H22a does, unless you use an aftermarket or Euro R intake manifold.

 

im confused so do we wire up the butterflies even though we have a gsr car and a gsr harness, which the gsr has butterflys. so what i asking, what another wiring needs to be done to a gsr harness<TABLE WIDTH="90%" CELLSPACING=0 CELLPADDING=0 ALIGN=CENTER><TR><TD>Quote, originally posted by CivicSpoon &raquo;</TD></TR><TR><TD CLASS="quote">Yeah but the H22a does, unless you use an aftermarket or Euro R intake manifold.</TD></TR></TABLE>

I apologies, I misread your post. I thought you said you didn't have a gs-r and that you were wondering why you had to wire the butterflies.
