Chevy/GMC 2500HD parts gathering

    This summer/fall, I will be buying a 2500HD, probably a GMC. I currently have a beater 88 K2500 with a hydraulic speedcast that I can use this winter if I fix the leaking oil pan and MIA donut gasket & muffler, but want to start getting together what I'll need to install a minute mount setup on this truck rather than waiting until the middle of winter and paying more.

    Since i'm not sure the exact year, I was looking to see if anyone has a quick chart of what push plates and wiring harnesses work for the years 1999-2005, as I've been looking at a 2001 Chevy and a 2004 GMC. Also a side question - is there any benefit for a 2 wire vs. 3 wire setup? I assume i'll be starting with a truck/plow that doesn't have either, so just wondering if there is a reasonable benefit from one.

    Thanks,
    Jeff

    I pulled up the install instructions from Fisher for 7169, and it appears to covers '03-'10 K2500-K3500, '02-'10 Avalanche 2500, and '01-'07 1500HD. Looks like before that takes a 7161 (I checked 2001).

    Thanks for the info on the 2 plug vs. 3 plug recommendation. I know I saw a writeup about switching pins, but otherwise the same 3 plug harness can be used for 99-present?

    the 7169's WILL go back to 99 GUARENTEED those are the ones u wnat beacause if u buy a 99-02 now and in the future u buy a 03-10 u can use the 7169's on ALL the trks U cant use the 7161 on the 03 and up their to short the 7169 IS keeping ur options open on more range of trks

    I don't want to assume that since no one called BS on this it is true (and no disrespect intended NHresident) - can anyone else confirm this is true?

    Thanks!

    His statement is 100% factual and correct. Don't get stuck with the 7161's because they only work properly on the 99-02. The 7169's will fit 99-07 so it covers all the GMT800 model years making your options much more broad.

    And I don't recommend running anything but a 3 plug or current 2 plug multiplex system (depending on the actual plow used). The old style 2 plug is long obsolete.

    7161 vs 7169

    You can use either the 7161 or the 7169 push plates on the 2001 truck the difference comes in the 03 and up where those years can only use the 7169, the frame mounting is the same, the differrence is in the distance the plates stick out from the bumper, the 7169 sticks out a little more than the 7161, therefore if the 7161 were to be used on the 03 and up models the head gear of the plow would come into contact with the bumper. A used set of 7161 should be cheaper than the 7169 due to demand, so it depends on what year truck you go with, and definitely go with the three plug system.

    And this would apply to both the 1500HD/2500 series and the 2500 HD? I know in the prior GMT 400 variation they had different frames, and I thought that carried forward but when I look up a NBS Sierra 2500 the min GVWR is 8600 and it says 7169 or 7161 for push plates...

    Thanks so much!

    1500HD/2500/2500HD/3500's all share common mounts on the GMT800 platform.
