WT 12DC plug shuts off with ignition

[oldmann]

Just got a new wt for road work.  It requires a full time LED warning light on the roof.  The cig plug turns off with the ignition.  The 27 to 28 fuse spot doesn't work like most trucks because it is only three pronged.  Any ideas besides running a wire?

Add the auxiliary switches for the snowplow prep group.  Auxiliary switch 5 is already wired to run a light on the roof.  Wiring should already be in the roof.  If you're truck doesn't have it already, parts are about $300.  Labor for install isn't that bad.  Worst part is taking apart the dash.  Once that's figured out everything goes together fairly easily.  Biggest benefit is having 4 additional auxiliary switches to connect to things.  These switches will have their own fuse box under the steering wheel that allows you to move the fuse over 1 slot left or right so they will turn off when the ignition is off, or stay powered on when the ignition is off.
