Hi all,
For my '03 Disco HSE7, I purchased the LR trailer harness... It only has 5 wires coming out of the harness that is hidden behind the tail lamp... Can anyone help me identify the remaining wires that are not being used? What I really want to find out is where the other ends of these wires are located in the front of the vehicle and whether or not I can use these wires for a brake controller and a trailer battery charge line... This is the information I have so far...
On the Disco harness side; LR trailer connector side; function
black; white; ground
green w/purple stripe ; red ; brake lights
green w/white stripe ; green ; right turn signal
green w/black stripe ; black ; tail lights
green w/red stripe ; yellow ; left turn signal
unknown wire function on the Disco harness side:
red w/yellow stripe
green w/brown stripe
purple
red w/orange stripe
I know that the LR3 has a commercially availably connector that will allow for a brake controller to plug into a harness located underneath the dash, near the center console... Does the Disco have this?
Any help would be greatly appreciated... In the end, if I must, I will just run wires for the brake controller and the trailer battery charge line, but I want to avoid that if necessary...
Thanks,
Jonathan
