I know this is to wire in the cas into a 2g but it gives the wire color and location.

If you read the diagram it says 1g CAS. Those are the supposed to be the stock colors for the plug.

And the diagram is option b from the same site showing the same wires and colors in the same place on the 1g CAS.
 
Sorry you're right.
However, the wires shown in the Mitsu factory manual for the later 1g CAS (91-94) are white, black, red, black (for pins 1,2,3,4). http://www.roadraceengineering.com/eclipsetech/justin/cas-blacklid.jpg
Read the 3rd paragragh in my link: "The later style CAS car harness uses White (1 - TDC), Black (2 - Crank Angle), Red (3 - 12v), Black (4 - Ground)".

So pin 1 (white) goes to ECU pin 22, pin 2 (black) goes to ECU pin 21, pin 3 (red) goes to MPI relay (for +12v), pin 4 (black) goes to ground.

Notice Steve also says in paragragh 3: "I don't know where RRE got the yellow wire from in their diagrams".
Maybe some aftermarket ones have it?

thanks alot guys, im going to go try it now. i will let you know what happens
 
I know old post, but I made my own adapter. This is the order, if anyone owns an '89-'90 DSM and wants to run a '91-'94 CAS and has the proper pigtails to make their own adapter. Numbers 1 to 4 are to be matched on the 89-'90 CAS connector to '91-'94 CAS connectors, the wire colors are '90 DSM connector colors. Ignore them and use the numbers if that's easier, since wire colors can change depending on where you get the pigtails from, the numbers are the positions you want to match.

I know now. The wires coming out of the 90 CAS are black, red, yellow, white they run to a male connector. That yellow wire ends there.

The car's harness has a female connector and the wires to it are 1.25 black, 1.25 red, white, black. (Ground, Power, TDC, Cam)

The 91-94 CAS has a plug on it, green top or black top, numbered from the index pin (so the reverse of the above picture) and the wires going to that plug are white, black, 1.25 red, 1.25 black. (Cam, Crank, Power, Ground)
