ok i have a 1993 accord with a busted up wire harness i have checked all junkyards i can find i have searched ebay and all over the net and still cant find the harness for it i dont have the secondaries on my engine so i dont know how to wire the regular accord wire harness into the h23 i have heard u can wire in the iab into the ecu and i could use the regular accord harness that way but i dont know what the iab is or how to wire it in?!? any help would be highly appreciated

 

you need to make sure you also got the iab solenoid and iab vaccum pod with your h23

 

preciate it but what is the IAB???? i do not know?

 

Secondary intake runners, they're little butterlys that open and close like your throttle except that they're smaller than the intake so that they allow some air to pass when they're not triggered.

The ECU sends a signal at a specific RPM to allow more air flow through the secondary intake runners, usually above 5700 RPM or so, this allows for higher torque at lower RPMs by choking the air through the manifold.

If you have the stock intake manifold with the H series motor you're going to lose performance if you don't have it set up to actuate the IAB.

Def. switch to the h23 intake manifold. You should not have to switch any wiring on the stock 93 wiring harness. The only things you might have to wire up is the igntion coil depending on the year of your h23 and the knock sensor. Got any info on your year motor?

 

i thought on 4th gen only ex model come with iab manifold?

 

yea its a 92 H23 but i dont know anything really else about it
