I changed the Temp sender on my 1993 Pontiac sunbird .Now when I ask someone to take the pigtail of the ripped the wires out and now i have no clue which wire goes to what.The new pigtail has only white wires not color coded.
There are three wires ,Black ,green and yellow but the new part only has white .Also the check engine light stays on now too.I am sure its a computer problem or something like that.

on the sensor connector there are 2 pins side by side and one under it. the one on the left is yellow right is black bottom is green this is as your looking at the end that plugs in not where the wires come out. I am assuming you have the 2.0 engine because the 3.1 engine temp sender only has 2 wires :)

Well the main problem is that there are multiple temp senders. So finding the wiring diagram can become rather complex. That sensor not being connected can make your check engine light come on.
Easiest thing to do is go to the junkyard find a gm car with the same motor or a sunbird. It is okay if the car is off a year or 2 and look at the connector. All car manufactures use the same parts and motors in multiple cars. Note the wire color positions you can just align the old colored wires with the new connectors uncolored wires. If you bring the new connector with you and put some masking tape on the wire you can easily lable it on the spot.
I know you are saying, "Why would I go all the way to the junk yard and do this??". Well it only costs you time and gas. You can buy a Chilton’s manual but there wiring diagrams suck and are at times hard to follow or missing things.
Next trick go to an AutoZone or other car parts store that offer to pull the codes from the computer for free. I'm positive the computer is throwing a code due to the sensor being disconnected. It could be using that temp sensor to calculate if the engine is cold and adjust the fuel mixture.

Don't worry about the check engine light until you get the wires hooked back up. The temp sensor wire alone would make that light come on by being disconnected.
Read your own question. It doesn't make any sense. You're going to need to get someone with electrical knowledge to help.

Get a wiring diagram for your sensor. It will tell you exactly which wires go to which terminals. The sensor if a NTC (negative temperature coefficient) and has a ground wire, a 5V reference wire, and a signal wire to the PCM. It is important you hook them up correctly. As for your engine light, it is most likely related to the sensor in question. If your sensor is not working properly, it could cause other engine problems, as well as poor fuel ecomomy and power. Hope this helps.
