Does anyone know which wire on the side marker lights is the + side ?
There is a blue and a black on the front markers on my truck. The PIAA lights ask for the pos side to tap into.
Thanks
Scott

hi Scott do you want your piaa lights to come on with the parking lights?

Re: + ? - ?
 

They have a led light that is inside them. In the wiring diagram they tap into the front marker light + side. They are the 525 model.

the piaa front brush bar lights have LED? or you mean your truck side maker lights have led

This is a 2008 but is likely the same on your truck. This is the front signal light, not the marker light. You need to tap into #2 term if you want them on with the parking lights this will control the relay to your front brush lights

It turns out the blue wires are the + side. The PIAA 525 have a LED light in them that is on with the parking lights when they are on prior to powering on the driving light or the fog light.
