I would like to add turn signals to the sides of my Big Country but would not have a clue as to where to look for the wires to connect them to.
Bob,
The turn signal wiring has a couple of known points:
1. At the metal junction box behind the pinbox where your 7-wire is wired in
2. At the rear cap at the tail lights
Then of course, the wiring is somewhere between those 2 points. Several guys on the forum (jnphobe and porthole) have wired their own. they'll chime in soon enough as to where they tapped in. Worst case, you will run a set of your own wires from the tail lights to mid-ship of wherever you want to place your turn signal lights. So for now, you can purchase and begin to mount the lights while others come here to tell you where they tapped in at.
This is a great upgrade - wish they were standard.
