    I have a 2008 F250 with a Vitramount Plow, with a 4 port isolation module. The headlights come on but the yellow turn and signal lights do not. The purple wire on port 4 and 3 have power. Port 2 ,Grey and purple, have no power. I can hear the ISO module clicking when the turn signal is on. Any help would be appreciated before I take the plunge for an ISO module. 15amp, Fuse is good.
