iat sensor plug different
 
2 Attachment(s)
ok so my 2000 civic has a different style plug on my harness then the jdm b18c r.. the swap has the round plug in the manifold.. is it possible to depin and just swap the connectors? or are the pins different?

The pins are different. Cut the wires to the plug in your hand with enough wire to reach the IAT sensor on the intake manifold. Then cut the other plug in the picture off 1" back from the black plug and connect the round grey plug to the newly cut wires... red/yellow to red/yellow and green/white to the green/black. Done.

The pics don't change the answer... they are different, so cut and then re-connect as I stated above.

it's best to use the heat shrink type of butt connectors made by 3M that you can get in the electrical section at walmart

after crimping down good, use a lighter to heat up the ends and they will melt/shrink closed

really i always thought solder is better for the smaller wires?

You could also just put the IAT into your intake arm

Yeah doesn’t matter Honda updated it in 96 and put it in the intake arm and airbox. It’ll be fine. Just use your OBD2 sensor and put it into your intake arm

The sensor range in manifold is far greater than what you would experience if the IAT is mounted in the inlet tube. So, if you intend to use an OBD-2 ECU, I would agree with HPH and mount it in the inlet tube. However, if you intend to use a tunable OBD-1 style engine management system, I recommend altering the plug and connect to the IAT sensor found in the intake manifold.
