Just to let you know I still 'tickle' this one in quiet moments. The wiring is being a pain. I can do it it just take to much room. Add to that, that the 18 positions that I thought I had for light functions is in fact only 16. Turns out that there are TWO positive feeders in each socket so the 10 pin plug is only an 8 pin plug. No worries, I'll just start again. Sigh!
I forgot a photo befor I started but here is where I am at now.
This is one of the headlight clusters. I had a fun job getting it to work. Mounted in place it would not work. Take it out, it worked... Turns out that the leg on the diode lowest in the photo was shorting out. The leg is supposed to support the rear board at right angels. They had just forgot to trim it down so it did not bridge the circuit board! Grr.
Here you can see the front of the truck with the headlights fitted. The wires in the center are spotlights on the front grill. This gives an idea of the amount of wires there are to find a rute for.
So here the wires that can be paired have been, so now the wires are fewer but longer. I also managed to break a few of fiddling about, but a soldering iron sorted those out. I will hopefully be in a place where the rear lights can connect to the relevant front ones, daylight running, positions, indicator and fog to name a few.
Then its the lights that are in the cabin that need sorting.
Comments and questions welcome.
Cheers
