just did a swap, i guess my friend didnt plug something right since my engine temp gauge doesnt work, but whenever i turn the car on itll go up a lil and then down to cold again so i duno wtf is going on.....is there a way to wire it up or connect it or w/e ?

 

On the OBD0 integras it's located on the back of the block. On the later models it's right next to one of the rad hoses.

 

93 integra, the block says 93 on it too....so it should be in the back, and wat exactly am i looking for ?
