Default H22 Dizzy Wiring? Where does the light blue & black/yellow wire goes to?

A friend of mines recently purchased a EK w/ a h22 engine in there, obd2 to obd1 conversion.

The wiring job that came with the car is horrible (a rigged up 1 peice harness (no shock tower harness/clips) just a whole engine harness running straight to the ecu.

I got most of the problems and bugs fixed.. now I'm left with just a dizzy wiring problem. The car is throwing a code 10 and a code 4. Something to do with the crank position or some sh*t.

I got 2 dizzy wires that are probably not rigged up correctly and was wondering if anybody knew where the light blue and the black/yellow wire goes to (straight to the ecu, which pins) this is on a p28 ecu. I heard that the light blue wire is for the RPM tach.. and maybe the black/yellow wire for the possible code 4 crank position problem I have. As of right now the car's RPM tach is not working and is throwing a code 10 & 4.


these 2 goes to.. ?

?obd2 rigged engine harness > obd1 conversion harness > obd1 p28 ecu?

*using obd1 h22 dizzy*

4 CKP - crank position sensor
10 IAT - intake air temperature sensor

And the car drives like a car with it's timing off. Very slugish and 0 power. The #4 code problem is what im trying to solve mostly.

black/ yellow is power. Posibly to the main really but not sure.
I don't have my pin diagram book. tomorrow I can tell you where it is supposed to go.

The code 10 is Intake Air Temp.

The code 4 is for a CKP which is because the blue wire is probably the CKP P wire and on an obd2a it goes to CO2 and if its obd2b it goes to CO8. and if its obd1 B15.

like what more do you need? I told you where the blue was supposed to go.

And what the codes were.

just find where the black/yellow goes.

CKY?

you mean CKP P

The reason the car runs sluggish is because the CKP sensor is needed to determine when to fire the injectors. the TDC sensor is down there as well so that should explain why the engine runs the way it does. Not to mention the IAT sensor is needed for correct startup and driving procedure.

The blue wire needs to go to B15.


The blue wire needs to go to B15.
