    On a truck with an rt2 plow mount, can I hook up to a rt3 plow with quick attach or is there some wiring differences?

    You can not connect to an RT3 plow with an RT2 mount. They're completely different and will not coincide.

    I dont know how that is even possile. A RT2 has a pair of forks that require the light tower to be vertical to enter the mount.

    The RT3 allows for the headgear to be forward, and simply align with the "C" trype hanger and is secured with a pin.

    Two ENTIRELY different systems. If you are attempting this you are trying to put a square peg in a round hole.

    Whatever

    See Figure 1 on the top of page 7 for RT2

    See diagram on top of page 8 for RT3.

    Now tell me that you have a RT3 plow on a RT2 mount.........

    I asked because my buddy has an rt 2 (at least thats what it says on the back of the moldboard) on his f450 and an rt3 on his f350. the mounts on the truck frame look the same, but he says the plows wont interchange. I assumed it was a wiring issue, even though the plugs look the same. I figured the other style of mount was an rt1

    Here's a couple pics, first is an RT2 mount and the second is an RT3. And both are for the same truck application. Pretty obvious that a plow (either 2 or 3) won't attach to both these mounts. Most misinformation stems from the fact that guys don't know which is which by identification.

    I guess the f450 is an rt2, minus smart hitch. I could have SWORN it said rt2 on the moldboard. I'll try to remember to look at it today. Anyway, they both have the rt3 type mount, is there a couple wires you need to add or something to make it work on a truck wired for a smarthitch plow or is it plug and play?

    There is no RT2 smart hitch. Smart hitch wasn't released until a few years after the RT2's were replaced with the RT3's. Might be an Frankenstein plow in that the moldboard was originally from an RT2 plow, or you're just simply fuzzy on your memory.

    However, you also have a SH1 and SH2 on an RT3...and that is where the difference in wiring stems from. A SH1 uses an 11 pin harness and the SH2 uses a 13 pin harness. But you can operate an 11 pin SH1 plow on a 13 pin truck and have all functions. And you can even plug a 13 pin plow into an 11 pin truck if you drill the extra holes in the truck side connector to receive the two extra pins. Doing this you will have all functions on the plow except for plow lamps because the 11 pin truck side has no dedicated plow lamp ground that is needed on a 13 pin plow.


    I followed you to the letter no problem but guys that aren't very familiar with it sometimes have trouble so pics seemed in perfect order, as they can oftentimes replace a thousand typed words and make it much easier for the guys to follow. :drinkup:
