If it is a single red wire that is not in the black shielding or wrapped. It could be for the VTEC oil pressure switch, VTEC solenoid, IAB's or really just about anything.
What pin does it connect to on the ECU side?
On the OBD1 ECU's the numbers are Odd numbers on top & even on bottom. This is numbered as if you were looking at the back of the connectors/as they are plugged into the ECU.

In the future, Sleepingcb3, please make your thread titles descriptive. Had Tishock and GhostAccord not already helped you before I saw this, it would have been deleted.

Would a better tittle would be "need help locating red wire?" may i ask why i need to be more specific also when can i post my ride?Last edited by Sleepingcb3; 10-18-2016, 02:56 PM.Comment

That is explained in the rules that you should have already read.
This site is intended to be a searchable database of information. Nobody is ever going to search for "quick help". They might search for "red wire", yes. If that is as descriptive as you can get, then that is better than nothing.
For over 13 years the information shared on this site to help individual people with their problems has gone on to help others with similar problems in the future. It will continue to do so, as long as people are able to find that information.

To answer your question, the red wire should go to the knock sensor, and it should be wired to pin D3. What ECU are you using? If it is a chipped ECU, such as a P06, P28, or P72, the knock sensor has likely been disabled, which would explain why it is unplugged. If you are using a P13 ECU, having the knock sensor unplugged would cause your check engine light to turn on (throwing code 23, if I recall...)

Again thanks for all your help and patience i also have this unplugged my check engine is on....the car is a 1990 and i believe that to be obd0 the ecu is a p28 not chiped and it is obd1 i also have a round green plug under the distributer any suggestions?Comment

All CB Accords are OBD1, as far as I know.
If the ECU is a P28, then it is tuned for a 1.6L Civic engine... it will do damage to your H22A if you do not chip and tune it correctly.
The round green plug is the VTEC oil pressure switch.
Read the thread at the top of this section marked "READ HERE FIRST". You will learn how to pull and interpret your check engine light error codes. Even with the wrong ECU, most of the codes thrown should be accurate.
In the meantime, don't push the car hard. Keep the RPMs under 3000 whenever possible. Don't drive it more than absolutely necessary. You don't want to do damage to the engine until you get a proper ECU for it. The H22A will likely want more fuel at higher RPMs than a smaller D16 (which your P28 is tuned for), and running lean is a good way to do serious damage to the inside of your engine.

Its running rich i know its wierd could you or any other member reffer me to a thread on how to hook up vtec ill order a new ecu this weekend what would you recomend? Its a h22a blacktopComment

The P13 is the correct ecu for the h22a. That's what I would suggest. Hold onto your p28. It can be chipped and tuned later on. If you plan on modifying the engine significantly enough to require a custom tune. You shouldn't need a custom tune until you upgrade your camshafts, do major internal work, or add forced induction (turbo, supercharger, major nitrous).
