I'm starting a small wiretuck and have things labeled except for one plug which i cant figure out what it is. It goes to the fuse box and has one single blue wire. its the only plug that has 1 single wire on the passenger side of the vehicle. here is a picture

 

Might be a plug for an oem fog option. Rsx had one identical to whats pictured.

 

does the 05 ap2 have a fog option?? i was kind of next to the orange connector i think. which is like abs or something.

 

Hmm, I have no idea. Perhaps it was for an aftermarket piece? Does everything else work to spec?

 

any accessory plug(s) i have ever seen(fog lights, trailer hitch wiring etc) from Honda, they have always had a dummy plug in place to prevent anything from getting lodged in the plug. This goes for under the hood plugs(fog lights) as well as interior and under the bumper plugs

 

dang so nobody knows?? I can get a different picture if needed. Also i have two plugs that go by the hood latch one is for horn one is left which i dont know. Thanks guys! Wiretuck and 500whp s2k is almost back up!

 

Could put a test light or meter on it and start turning things on and off till it does something.

 

I'm just going from memory here and I would have to double check but I believe the stock horn has 2 connections on it. One for the steering wheel horn and one for the stock alarm. I could double check though.

 

Can you take a better picture of that first plug? Also it reads like your talking about it under the hood, but in that picture it looks like your on the passenger side of the car but inside the car.... Can you narrow it down for us?

 

sorry havent taken another picture yet. It is from the engine bay. I am doing a wiretuck and pulled all the wires through the firewall. It is a single wire plug and it was next to the orange plug i believe. I think it goes to the fuse box and worst comes to worst, i can trace it to the fuse box. also does the horn have 2 spots to plug in?
