auto sparky woes and errors
Please make sure the auto sparky KNOWS what he is doing and has prior LR Disco experience. I just engaged an auto sparky thru Ace electrics with specific instruction that he was to know what he was doing. Well he did not have a clue and said he had very little D4 experience nor had put on a P3 onto a D4 before - he said could not work out why there was tail light power at Pin 5 and 7. He did not have a D4 workshop manual.
After he finished there was no more tail light volts at pin 7, and pin 5 was not working properly. I went thru sniegy's notes again and then it made sense to me. I completely reversed all the sparky's work - reconnected the divided blue and brown wires in the loom and started again. I check the trailer connector with a trailer plug tester (that the auto sparky did not have!!) ..and all pins worked as they should with tail lights power at Pin 5 and 7
I did not need to remove the LHS tail light. The sparky was working on the trailer loom inside LH rear corner. He cut the blue wire? why. Can someone tell me what the blue wire does in the trailer loom??
Sparky cut the brown wire BEFORE it divided into the black and brown wires. No wonder why the Pin 7 tail light did not work any more. He connected the P3 thin red wire (brake sense) extension to the divided brown wire (this would then connect to pins 5 and 7, then fed the P3 thicker blue wire extension onto the red (brake) wire. The P3 blue wire is the power wire to activate the electric brakes, and the P3 red wire (brake sense) is connected to the brake light wire in the loom on its way to Pin 6. The sparky had the P3 red and blue wires the wrong way round ( i dont think he knew what each wire did or he forgot that he had wired the extension cable the other way round - P3 red wire to the cable black wire and the P3 blue wire to the cable red wire) and divided the trailer loom blue wire (? why) and the brown wire too early.

My repair to P3 end - notice I have changed over the wire colour connections - not critical if one knows whats going on at the loom end

Sparky's loom connection - note blue wire cut, and brown wire severed too high before the black wire comes off. Result no tail light to Pin 7. Note that the loom red and brown have the wrong wires from the P3 connected also - wrong way around

My repair work - reconnected the blue and brown wires that were cut earlier ( had to use some orange wire to join them back up again). Then cut brown wire after the black wire comes off. My black wire that is joined to P3 blue wire is now connected to the trailer connector end of the brown wire.

If someone can tell me how to properly add photos to this Post I would love to add them here to show the botched job and the repair work that I had to do. I'll give the attachment a go but not sure I am doing it correctly.
