Placed this question originally under "Electrical", but guess my chances are better here... Hope someone has already done this operation and is willing to share the experience!


I'm planning on adding a switch to the electrical fan, to be able to shut it down when - i.e. - swimming in mud an so on...

Anyone knows which cable to/from the fan I can add a relay, and on to a switch in the cab? To the fan itself is attached a blue and a black cable, and from the connection there are three cables...

I'd just insert a "T" connection to the power to the fan, run a new line to a dash switch and be done w/it.

 

Why not just manually wire the ground thru switch, that currently goes from the temp sensor to the fan.

Generally its better to interupt a ground, than a hot wire, unless you install at the minimum an inline fuse.
