    i got a used plow last winter.has 4port 3plug unit 26400. plow works good. mm2. havent figured out the lites yet. short and long wire harnes missing a plug and socket. notsure if fisher harnes had double directional bulb sockets like ones on truck. i willfix these soon . I thought maybe the plow side lites would aleast come on. tried the neg and pos lite configuration. nothing. checked the 2 fuses. good with continuity. gave plug ends a little dialectric greese.has power on only 1 pin at the 11pin plug. still nothing. only conection havnt checked is small wire on solinoid cant get loose .whole thing wants to turn. need a small ignion wrench or somthing. may call the fisher dealer soon if need to thanks.bill

    26400 is not the correct module for that application. You should have a 27781 green label module. Although, the modules have been known to work, for the most part, in some incorrect applications... so, can't be sure that's your issue, or if so, your only issue, as I'm not entirely certain what the rest of your post about the plugs and sockets means. :confused:

    EDIT: What year truck? Actually, if the truck is the earlier body (99 and older) the 26400 is the correct module.
