    If you have a Two headlight system the wire kit you need is a 8439. The composite halagon headlights take a 8438. The yellow iso module will work, the following chart will sho you all the componets needed. The 8439 and 8438 will show you need a white iso module but the yellow will work. Make sure you have the proper wire harness for your truck. http://www.fishersnowplows.com/pdf/28562.04_011507.pdf
