    ok so when using eMatch for my truck, i am confused as to how you know what wiring harness your truck needs. How do you know if you need one or the other 3 or 4 port?. I don't have DRL.... see my signature, same truck (#2).................please someone give me a explanation on this, i am piecing together parts via craig's list and ebay for the truck side parts. Found a a nice MM2 just plow and headgear for $2,000 bucks 1 season old!!!!!!!!:confused:

    4 port module is obsolete. the 3 port replaced it a few years back. on the 4 port 2 of the ports were for headlight wiring harness. the 3 port simply combines the left and right side headlight and side marker cables via 1 port.

    You can typically get them for $100 or less off the shelf.

    Fisher's website has all the wiring installation instructions and push plate installation instructions you will need, it's really not that hard if you are mechanically inclined, just be sure to take your time seeing how its your first install. Also the 3 port module uses a different headlight wiring harness from the headlights to the module than the 4 port uses so if your piecing things together make sure you get compatible parts, the control harness and 11 pin module to plow headlight harness are all the same

    I did my 02 GM. It was fairly straightforward. The real trick is taking the time to route the wires neatly. I think the only real advantage the dealer / installers have over the average mechanically inclined person, is they know from redundancy, what works & looks best on the wide array of trucks out there. The best peice of advice I can give you is to take your time, and follow the install guides even though most of it appears to be for the simple minded. If you buy used components, you can also download the installation guide for your specific kit & Truck. Read them over from start to finish before you touch your truck. follow it, then double check it once everything is in place. It wil save you from tearing it all apart.again, later on. If you need a hand locating them, just ask. One other thing, and this may've just been me, but some of the wording leaves some room for interpertation. If you get turned around, a quick search on here can prove to be very usefull.

    I installed all the wiring on my western myself. I had my dealer install the mount since it was January and I have no lift or heated garage to work in. I installed a used 4 port off of an 02 Dodge into a 2008 Chev Silverado. I bought the headlight harness from western, but after doing the install realized the only difference in harness is the factory headlight plugs/ connectors. All the isolation module does is turn off power to headlights and transfer to plow. Then returns power to truck headlights after plow is disconnected. You can still wire any plow lights on a seperate switch wired to a new fuse and just turn off the truck headlights yourself. After installing all the wiring and spending money on harnesses, I think the old school way would have worked just fine.

    I got 7170-2.....That's what the Fisher eMatch told me to get..........the part i don't understand is when i change to a laramie edition the mount part number stays the same. Now when you go and look at the parts list in the tech section of Fisher's website it list the two as 7170-1 and 7170-2 first being non laramie and the second just says ram 2500 06+

    I was a bit confused a while back about them. -2 fits everything -1 fits everything except for larime. I laso belive -1 has been superseeded by the -2? When I say everything I mean 03 and up dodge 2500 3500
