The old one has, orange with white stripe, black with blue stripe and a purple with wite stripe.

I am guessing wht/org to wht/org ,blk/blue to blk/blue and org to purp/wht stripe?

thank you any help will would be appriciated.

ANSWER: First, I need to know the year/make/model of the vehicle in question. Second, speed sensors have only two wires connecting to them. And that you have a sensor prewired seems a bit odd.

QUESTION: After some more research i found its the sensor on the transfercase that measures the shaft speed. 1997 jeep grand cherokee laredo 6 cyl 4x4.

Answer
The sensor you are referring to is a Vehicle Speed sensor. Its primary function is to provide vehicle speed information to the PCM and Instrument Cluster as well as other modules in the vehicle. I would go ahead and wire it the way you outlined, you will have no speedometer operation if it is wired incorrectly.
