Black usually indicates a ground. Take a picture if you want a positive answer.

Those go to your iat sensor from what my car looks like. Mine has a green with yellow stripe and red with yellow stripe


Black is universally ground I believe is it not??

Yes very easy. So are there wires on your IAT already?
Iat takes two wires as it is a two wire connector that plugs into the sensor that is mounted to your Throttlebody.

If so what color are the wires on your IAT?

We do need a more lightened picture though. If you show me what you got to work with we'll get this fixed no problem

Not sure on limp mode. Lets fix it and find out

LOL I can't see crap, where is that picture being taken from the same spot where your iat sensor is?? You can see that picture clearly? Which wire do you want to know anyway? the red one I'm assuming that goes from bottom right corner to the top

yeeah those wires you have are aftermarket I believe. The orientation of them doesn't match the stock locations.

Now if he used that harness (F22) you have to cross reference where the h22 components are on the motor(where the wires go) to where they were on the F22 harness. If they are in different spots he would have to run jumpers and splice the connectors to where they would need to go on the vtec motor. Doesn't look like alot of differences. Have to look at it more in depth though

yeah go do that. I'll keep looking for the blue wire.

You got what you need to connect it all? You have the sensor in the throtle body, so you need the connector and those two wires hooked into it on the appropriate sides.

yeah, that still leaves it inconclusive for us though. If its not hooked up on civics though and their tach's work whats that wires purpose than?

I also see now something called a tachometer connector on the passenger side around shock tower, whats that for..?

yeah, there are suppose to be wires on IACV. You didn't look at the h22 diagram lol c106 for h22 and f22 so there shouldn't be any problems there with your harness working with your h22

those are shown as black/ blue, and yellow/ black though. which means black with blue stripe and yellow with black stripe
green/wwhite and red/ yellow is IAT sensor
