I promised to send a brief description and pics on this job wot I did a few days back. Pics (including one showing the key tools though not all) and including some showing where and why the natural position of the fogs is determined by a convenient (outmost) flat panel in the bumper. PM me or just continue the thread if more advice needed. my rough notes from the job are:
Here are the picsHad to remove towbar to gain access, but rested it on upside down washing up bowl and swung it to one side rather than disconnect wiring.
Used bullet connectors from master foglight to 2nd foglight
Soldered wires to 2nd foglight as had no spade connectors
Used spare grommet to plug bolt hole from old foglight but it is a bit loose and will fall out, so need a bigger one.
Plastic bumper v easy to cut by small drill holes then minisaw, file to smooth edges. I used quality masking tape and the fog light 'frame' interior to mark out the area to be cut so that I could get the cutout level by eye and check identical distance from midline using boot latch as centre point. This was undersize as it did not allow for wall thickness of the 'frame'. So I then made a cardboard template with cutout correctly sized for frame recess to fit in, and taped this over the marked out frame on the bumper before using a sharp modelling knife and steel rule to cut the maskng to correct size. I used a small drill bit to stitch drill holes all around the cutout along the line of maskng tape, and joined up the holes near each corner so I could insert my saw and saw along each side. I did not completely saw along each side until the end of the cutting. This kept the saw from jamming as it does when the panel to be removed starts to move a lot. TIP - I started by drilling holes in each corner of the masked area. After each hole, I felt behind the bumper to make sure that I was drilling into the correct space bhind the bumper, where there was room for the foglight to fit.
NB - the bumper plastic was very easy to drill and saw. I finished off with a large flat file as inevitably the hole needed a little easing to get the frame to fit into it.
