99 ford with fisher SEHP-wiring problem

    I recently bought a used (1998) M.M. SEHP plow set up for my truck 99 Ford Super Duty with 7.3). We put in the harness according to the schematic from Fisher. I have a problem that the high beam indicator stays on now and when I change to high beams it looks like there is a ground problem (light is at half the intensity). There is no problem with the low beams (on the truck)

    Last night when I hooked up the plow and plugged everything in there was no LOW beams on the PLOW lights just HIGH beams. I'm so confused.

    I talked to Roger at Fisher and he suggested checking the solenoids. I changed both solenoids but no change with the lights. Tried calling Roger back but he must be busy, no call back yet.

    Any help would be appreciated.

    Thanks
