    Will the truck side wiring and ISO module out of an 02 Chevy work in a 94 Chevy? They both use the same headlight configuration?

    You didn't give much info on the trucks but i just guessed as what some of their options would be and ran them through Fisher Ematch and they came back with the same harness number.....you should run them both through the Ematch with all the details to get your answer for sure.

    If its a 4 port Iso system they ARE NOT the same. Each one of your trucks use a different Iso mod and light plug in harness's.

    Likely what you did when you used the ematch was checked the numbers for a 3 port Iso setup...which is different from the needed components for a 4 port system between these two trucks.

    Doesn't it depend on the plow also ? My '94 with MM1 had no ISO.

    Yes of course it can. OP didn't mention anything related to the plow side so we have to assume he's simply swapping a current plow from one truck to the other.

    Best we can do with limited info..
