Icon6 2002 Honda Civic EX Wiring Diagram

Just picked up an 02 EX that has all sorts of wiring issues. There are a few connectors that are unplugged and I'm trying to sort these out. Does anybody have access to a diagram for under the hood?

You can pick up a Helm's manual for the underhood wiring diagram.

I also have no idea what this plug is, it's near the cruise control module however, it's not the plug that I see on others of the same year and model. Check it out....

Coupe LX and EX has a 12P Black harness connector for the cruise control actuator.

1 WHT/BLK
2 BLU/YEL
3 LT BLU
4 —
5 BLU/WHT
6 BLK/ORN
7 LT GRN
8 GRY/RED
9 LT GRN/BLK
10 BLU/ORN
11 BLU
12 BLK

See if the wiring colors match up.

Wire colors confirmed. So are you suggesting that I swap out the cruise control module since it doesn't match the harness plug?

Is the car a sedan or coupe?

That cruise control actuator in the picture looks like the part for a sedan. If the car is a sedan, the previous owner may have used an engine wire harness from a coupe, which won't match if the car is a sedan. That would explain why there are a few connectors unplugged.

No, the car is a coupe. Different actuator?

From your photo, it looks like the cruise control actuator for the sedan; however, it may just be how the photo looks, and that actuator is for the coupe. Try plugging in the 12-P connector into it; if it connects, then the actuator is correct.


The actuator for a coupe is different than for a sedan. The sedan has a 4P black connector instead of a 12P connector.

In this parts diagram, part #3 is for a sedan, and part #4 is for a coupe.
