Could I wire heater blower motor switch to fuse box using unfused spade on fuse box?

[HeavyHauler]

On my 68 C10 I dont have a brown power wire from the heater blower motor switch on the dash that leads to the fuse box. My C10 is a factory heater only truck.

I plan to make my own power wire and plug it into the fuse box at the terminal that is labeled IGNITION UNFUSED. I figure that I will add an inline fuse the same as what the heater fuse is.


Will this work without causing problems? I already installed a new blower motor harness which connects the blower switch at the dash to the blower motor resistor and to the blower motor.
