Finally getting stuck into this........
I have most of the front end off for an EGR cooler and thermostat replacement, Not a nice job! Smoothed out a bit with the fitting a Wagner Intercooler though
I am deviating from the "plug and play" looms slightly,
I am trying to replicate the original VW wiring and fuse locations for xenon's as much as I can. (I have a copy of ERWIN to refer to) I have not worked out how to get photos from my new phone onto the PC yet but I am taking loads of pictures as I go and will get them up here.
Anyway while the front end is in the service position I thought I would get stuck in, I am replacing the loom behind the bumper from the Left headlamp to the T14 & T10bl sockets with a new VW loom, so that is sorted.
From the T14 & T10bl sockets behind the bumper, I will replace wires as needed to reach the BCM and fuse box.
Right hand headlamp same as above. It is just the wiring that goes to SB6 & SB28 fuses from the headlamps I am not sure about. for example,
It looks like I will need to use fuse SB6 for left headlamp which is a Terminal 56a feed where as the original fuse was SB5 which was a 56b terminal. Im not sure what the difference is between 56a/56b?
So far....
I have ran a new 6mm2 wire from a spare location in the "A" fuse box which I have fused with a 30amp midi fuse (its all I have at the moment) This is ran into a spare grommet behind the scuttle and will be split into 2 x 2.5mm2 wires. These will then feed fuses SC12 and SC14. These will also be fused at 30amp and then feed the BCM T73a/63 & T73b/68. The original wires for these locations will be isolated.
I am struggling to get the pins out of the original T17 switch plug, I have Laser terminal removal tools but they seem to be impossible to use on this plug. This kit--

I have lifted the little tabs up while using the tool but It took me an hour just to get one out! I think Its going to get cut off tbh! The tools work ok on other sockets so far, just this one that's giving me problems.
Tomorrows job will be remove front seats, carpet and A pillar trim and so I can make a start on laying the wiring for Rain & light sensors and front/rear level sensors.
