Easy does it. It's easier than you might think. Remove the fuse box cover where you will see the CJB. There are 4 10mm bolts that hold it in place. Remove the bolts and carefully slide out the CJB. It will come out enough for you to see what lurks behind. There you will see 2 clusters of dead ended wires. The one farthest to the right is the cluster of four that you want. Look for the white tape. They are also labeled as AUX 1-4. 2 of the four will be thicker. There is a link here that takes you to the Body Shop buletin that actually shows a picture. If I was on my other puter I could show you. Enjoy then get your AIC up & runin! It's /ubbthreads/images/graemlins/smokin.gif
