Was looking around and this is what i found after posting my question
1993-1994
2.3L - off the PCM go to pin 4, which is a tan wire with a yellow stripe or to the ICM and splice pin 12, which is a tan wire with yellow stripe. This is the same for the 4.0L, except for the ICM connection, it will be pin 2 instead of 12.
3.0L off the PCM will be pin 4, which is a white wire with a pink stripe or you can go to the ICM, and splice into pin B, which will be a tan wire with a yellow stripe.
1995 to present i thinkyou can splice into the PCM. You will need to splice into pin number 48, which will be a brown or tan wire with a yellow stripe, to obtain your engine RPM signal.
