Here is a headlight wiring kit for 3 port isolation modules for some trucks with HB3/H11 headlight. This is a Genuine OEM Western/Fisher/SnowEx 29400-7 headlight wiring kit. This kit will only work with 3 port isolation modules (it will not work with 4 port modules). This wiring is for vehicles with Hb3/H11 headlight bulbs. Check to make sure your vehicle has HB3/H11 headlight bulbs. If your vehicle does not have HB3/H11 bulbs, this harness will not work for your truck. This wiring will work for 07-13 Chevy/GMC 1500 and 07-14 Chevy/GMC 2500, 3500. ***If your truck is an 07, it must be the new body style 07. In 07, you could buy the 99-06 body style called an 07 Classic or you could get the all new 07 body style.*** To check what style headlights you have, take a look at the lense of the headlight from the front of the truck. It should have the headlight stamped on the front of the lense. ***BEFORE BUYING***, use the Quickmatch feature on the Western Website or the eMatch feature on Fisher's website to make sure this is the right harness for your truck. Part numbers in this kit 29861-4 (11 pin harness that plugs into Port A) and HB3/H11 adapter harness 29499-1 (plugs into ports B and C).  There are other small parts included as you can see. When using Western Quickmatch or Fisher Ematch, they list the plug-in harness kit as 29400-7 which is made up of 29861-4 (port A) and 29400-7 (ports B and C). What you see in the pictures is what you will be receiving. Thanks for looking. Feel free to ask any questions. Check my other listings for more plow and spreader parts. Free shipping to US only.
