Chris's Navara Tail Lights

 Chris has a Nissan Navara and he is building his own Tray back.
I am helping out with the tail lights.

New lights are:

LOAD RESISTORS
Apparently LED lights require a load resistor

6 Ohms across each circuit.  These are not current limiting resistors.  These resistors simply get hot.  Very hot.  As I understand it, Australian design rules have some requirements in regard to vehicles detecting blown bulbs and they do this by measuring current.  These resistors apparently simulate bulbs. When we have more time, I will experiment to work out whether all circuits need resistors.



DEUTSCH CONNECTORS

Jaycar have a set of instructions for assembly

DMAX Plugs cut off the vehicle wiring harness and we replaced with Deutsch.  If I was doing it again, I would use Molex so I could parallel up the wires for the load resistors.

Brown = Tail
Red=Brake
Yellow or green is the indicator.
Black is GND in the corner.  We used white








Clamped the resistors between two pieces of DIN rail.

I made this tool by grinding down a small scred driver and then using a hacksaw and file to cut the groove.  The back of the screwdriver was ground down too to make it thinner to fit in the slot.



Once the green bit has been removed, the plastic retainer is pushed aside, can use a small flat blade screwdriver for this.  Then pull the wire from the back.






Finally!
