found this random plug the other day and dont know what it goes to, i have been told map sensor but the colors arent right and map is plugged in, i have looked everywhere and cant find an answer the colors are white, green, yellow/green its on a d15b vtec idk what was in the car before but he did a hack job of everything and im trying to straighten it all out
I mean, other than the fact that it's round, and only has three pins...There are very few things that plug could be. An O2 sensor is definitely not on that list. Without looking up wire colors, I would guess it's either for the MAP, or TPS.
Then the previous owner may have fucked with the wiring harness.
Honestly, if your car isn't doing anything "weird", and the CEL isn't on, I wouldn't worry about it. A lot of stupid goes into some people working on cars, and trying to reverse engineer that level of stupid can sometimes cause more harm than good.
It could be the wrong harness all together. I'll be using an auto harness in my stick car because I pulled the vtec engine out of an auto car. There will be unused plugs unless I actually go ahead and modify the harness which I probably might or maybe not idk

and this would be the guy that does things like this...
the only thing that happens with the one in the pictures plugged in is it idle surges but other than that cel goes off and runs fine, with the yellow/red wire one plugged in it runs ok but cel is on i guess ill just use the one in the picture and try replacing map sensor to see if idle surge stops

I laughed my *** off when I read his post, thats coming from a guy who was trying to talk down to me about v6 6spd swaps. Lord.....
My wife's car is the same way. The engine harness on the car has one map sensor plug and then the engine bay harness has the stock map sensor plug for the original motor.
Sounds like you have a swapped in motor that had the map sensor on the throttle body so uses the engine harness plug. While the original motor had the map sensor on the firewall and used the plug on the engine bay harness from the battery side.
Usually people don't swap the engine harness on the motor itself when doing the swap so dual map plugs is sort of common being Honda didn't keep to a standard location for the map sensor on the 92-95.
Tom, I don't recall 92's having the map sensor on the firewall, I think only the ef models had them. Not even sure if the 92-93 integra's had firewall mounted map sensors.
Unless he was boosting and used a separate harness, separate map sensor, to accomplish his needs.
Do you have power steering? The plug for the ps pressure switch is also a 3 pin and plugs right into the map sensor.
No it is a round 2 pin plug that is identical to the IACV, IAT, knock sensor type plugs

92-93 cars with the D15B7 (DX, LX) had them on the firewall
