    I have a 2001 Ford F250 that in 2004 or 2005 I bought a MM2 Stainless X-Blade plow with a 3-plug setup.

    I just purchased a 2008 F350 and wondering if I can use the same wiring harness for the new truck??

    The isolation module (4 plugs) does not have any part number, but a couple of the cables leading away have part numbers: 26349 and 26354.

    Thanks in advance!!

    Look it up on fishers website I believe they break the mount down & wiring harness separately see if the part numbers are the same.

    I believe you need a 3 port isolation setup.

    I think it 08 diesel may require the 3 port blue soft start module, Im not 100% sure on gas.

    yea, the lights are different. those harnesses you have are for the HB1-HB5 lights, and the 2008 would have H13, or 2B. and Brad is right, 2008 Fords were the ones that Western had to come up with the soft start module (29760-1), and is still what they recommend using. gas or diesel doesn't make a difference.
