The rear wings, tub and spare cover are back from http://www.specialisedpaintwork.com/ for some touch up work and removal of all the stone chips on the wings! The wings were starting to look more stone chip hole than paint on the front. To protect the wings this time I purchased some 3M VentureShield from https://www.invisiblepatterns.co.uk/ – I made a pattern using paper first then cut out the 3M stone chip protection film and applied. It took a lot of soapy water and work with the squeegee to get everything stuck down.
After fitting the stone chip protection film, I installed the new 3D printed light covers:
Wiring updated for the new inner LED lights:
Stuck the rear tub back on, this time using A316 stainless ‘A4’ nuts and bolts, these shouldn’t go rusty as easily as the previous 304 stainless ones. Got the nuts and bolts from https://www.westfieldfasteners.co.uk/
Decided to use vinyl wing piping from https://www.woolies-trim.co.uk/ instead of the rubber trim that’s been on there since 2005 (that had started to go solid). The texture on the trim is very nice.
Next it was time to tackle some electrical, this tool from https://www.powerprobe.com/ (via https://www.summitracing.com/) is an invaluable tool for dealing with 12v car electrics. It will tell you if you have a ground, or a positive (and how many volts), plus you can use the switch to send a ground or 12 volts to the item your are connected to. A good way to test relays, bulbs, LED polarity etc.
Reconnected the 4 pin water proof connectors and tied up the excess cables out of the way of the tyres.
These are new two pole Lucas 403 bulb holders and a very cool set of LED lights that output both white and red light spending on which pins you connect up. They cover reverse and fog, which means I can run twin fog / twin reverse lights! The old Lucas 403 holders were starting to look a bit rusty so the new ones were good to get anyway.
Finally, an extra cross over cable is needed to bring the 12v+ fog/reverse to both sides of the car:
Finally, due to the indicators now being LED they ran in super insane broken bulb mode. As such the flasher relay needed to be swapped out. I had gotten an LED flasher from S-V-C https://www.s-v-c.co.uk/product/led-flasher-relay-12v/ it’s pin out is reversed from the BMW flasher relay and the ground is on a wire from the top. The flasher relay comes with a polarity swapping attachment so it goes right into the same connector as the stock flasher. The ground I’ve attached to the same location as the horn and other steering wheel wiring grounds.
Finally, some assembled shots:
