Its always possible
.. Your gonna want tap into the Positive wire right before your actual light bulb. Now you can try 2 things here...
Option 1 (single relay setup) Attached image for this setup.
1. Run the tapped wire to a switch in cab.
2. Run a Positive wire from the switch to a relay we will call this wire your control.
3. Wire your relay up, ground, positive, and Control.
4. From the accessory spot on your relay and wire to your new lights.
If this causes strain on your ECU use option 2.
Option 2 (dual relay setup)
1. Run tapped wire to Relay1, we will call this Control1. Your gonna want to make this run as short as possible.
2. Wire relay 1, Ground positive and Control1.
3. From accessory spot on Relay1, wire this to your switch.
4. From the switch, run a wire to Relay2, We will call this control 2.
5. Wire up Relay2, Ground, Positive, Control2.
6. From accessory spot on Relay2, wire this to positive on your new lights.
You can get these relays at your auto parts store.. What I did is asked for there parts book. Found ones with a mounting hole, and asked for prices on them all(to find the cheapest of coarse). I had to order them so I ordered like 8 of them at 1.99 each.
Legend for Diagram on relay.
Positive = 30
Ground = 85
Control = 86
Acc = 87
If Neither of the options work, well them I am at a loss. Option 2 should put like a 1/10 of a watt load on the + wire from the light bulb.
Here is the wiring diagram fro Option 1, its using a lighted switch thus the extra wire on switch (a ground).
