Keith,
You should be able to use your low-side PWM control to operate a high-side FET transistor. Maybe through an opto-isolator.

Google "high side switch" returns several.

I've never used them in my own designed projects, but we repair snow plow light switch controls that use them.

My Staff says I never listen to them, or something like that
