Could anyone help me, I need to replace my cam [housing] (CAS), but the one I got is from 89 to 91 and the harness changes, any help?

"My CAS problem is this, my CAS is an ‘89 - ‘90 and my [harness] connector is a '91 -‘ 94"

GST 1994 Eclipse my CAS is damaged, I have no spark in 2 and 3, so I got that CAS, but it is older, I don't know the wiring order, could you help me, thank you

Estas seguro que ese connector es para el cas? No es del tps?

El connector de 1994 debe de tener. 2 negros 1 rojo y un blanko alambre


"Are you sure the connector is for the CAS? And it’s not for the TPS?
The connector of the 1994 CAS has 2 black, 1 red, and 1 white wire."

es posible, tps igual con el cas el conector y produce chispa si está al revés ?

Google Translate:
Is it possible, TPS is the same with the CAS connector and produces a spark if it is the other way around?

Tus colores no los encuentro en ningun diagrama.

I do not find your colors on any diagram.

@Justin DuBois this guy is trying to wire a 90 cas into his 94 harness however his wire colors dont match what theyre supposed to be. Any ideas?

We need a help on this, I don’t have the details on the 90 sensor internals, but the 94 harness we can use the pin locations to identify power, ground, and two output signals, crank and cam
 
Haber si logramos solucinarlo

Estoy cambiando el cas, porque según entiendo por eso no tengo chispa en el 2 y el 3 verdad, el cas lo tengo malo, por eso la chispa no esta correcto,!
Solo tengo chispa en el 1 y el 4, cambie cables y bobinas y lo mismo sucedió
Mi cas está malo.! Verdad ?

Google Translate:
Let's see if we can solve it

I'm changing the CAS, because as I understand it, that's why I don't have spark in the 2 and 3, right, I have a bad CAS, that's why the spark is not correct!
I only have spark in 1 and 4, I changed cables and coils and the same thing happened.

My CAS is bad! Right?

Los colores de tu connector no los encuentro. Pero el 90 CAS es asi.

Rojo es Poder.
Negro gordo es tierra.
Amarillo signal
Negro flaco signal.

Con un volt meter chequea cual es tierra y poder solo te quedan 2 si no preden los cambias los cables.

Google Translate:
I can't find the colors of your connector. But the 90 CAS is like that.

Red is Power.
Fat black is earth.
Signal yellow
Black skinny signal.

With a volt meter check which is ground and power, you only have 2 left if they don't turn on, change the cables.

From https://www.dsmtuners.com/threads/1990-engine-ecu-mpi-circuit-diagrams.540595

90-mpi-circuit-8-75-jpg.662594


91-94 CAS

So the question of what that connector is really for remains.
Everything you need is in these diagrams:
90 sensor to 94 harness

Thin black/white (Cam Position signal 5v) - goes to Pin 1 (B-32) vehicle harness
Yellow (Crank Position signal 5v) - goes to Pin 2 (B-32) vehicle harness
Red (12v from MPI relay) - goes to Pin 3 (B-32) vehicle harness
Black (Ground thick) - goes to Pin 4 (B-32) vehicle harness

I might have pin 1 and 2 backwards, so if it does not work, you can swap these two wires as @evil_eagletalon mentioned

Todo lo que necesitas está en estos diagramas:
Sensor 90 a arnés 94

Delgado negro/blanco (señal de posición de leva 5v): va al arnés del vehículo Pin 1 (B-32)
Amarillo (señal de posición del cigüeñal 5v): va al arnés del vehículo Pin 2 (B-32)
Rojo (12v del relé MPI): va al arnés del vehículo Pin 3 (B-32)
Negro (tierra gruesa): va al arnés del vehículo Pin 4 (B-32)

Es posible que tenga los pines 1 y 2 al revés, así que si no funciona, puedes intercambiar estos dos cables como mencionó @evil_eagletalon.

Assuming that somehow this is the CAS connector, is it possible that the problem is the wires to the connector and not the CAS? They (pins 1 and 2) look broken in your picture.

The black top CAS is not likely to be bad and better than the early style.

Possibly I'm just helping cause its in Spanish. He said he doesn't have spark to 2 cylinders
 
Intercambie las bobinas y vea si la chispa no las sigue.

Swap coils and see if the no spark follows them.
 
No tengo pulso, en el inyector 2 y 3 que será?

Google Translate:
I don't have a pulse, what could it be on injector 2 and 3?

no tengo chispa y tampoco pulsos en ambos

Google Translate:
I have no spark and no pulses in both.
 
Do you have a volt meter?

I would confirm the sensor function with a volt meter outside the car. If you wire the sensor to 12v power and ground, use a volt meter to sample the 5v signal outputs. As you turn the cam input on the sensor 360deg, you should see the voltage on the yellow and thin black wires toggle from 0-5v.


¿Tienes un voltímetro?

Confirmaría el funcionamiento del sensor con un voltímetro fuera del coche. Si conecta el sensor a una alimentación de 12 V y a tierra, use un voltímetro para muestrear las salidas de señal de 5 V. A medida que gira la entrada de la leva en el sensor 360 grados, debería ver que el voltaje en los cables amarillo y negro delgado cambia de 0 a 5 V.
