Check out installuniversity.com. You tap into a white wire off the PCM. I believe it is the #10 pin.

make sure you are looking at the connector the right way to find pin 10....
mad a custom cable for something once..and the connector was from the inside view...not the outside view...so basically I read it left to right and it should have been right to left..... its ok though...I figured it out right away....
you might just have the wrong pin somehow
