I just finished getting through to the engine. I bought a set of wire feeding rods from QD for a few pounds to do this. without such a tool it would be impossible.
Below the brake master cylinder on the passenger side you can just see a large electrical feed going through the bulk head.
There is what appears to be a hole in this below the main wiring loom. This a proper access point, verified from in the car.
I punctured the grommet with the sharp end of a 1/8" chainsaw file and then pushed the feeder tool through into the car. I managed to lassou this with a loop of wire and pulled it down and towards the centre of the car as me Mrs shoved it into the car from the engine bay. These rods are about 3 foot long and just the correct thickness for the job. The wire was attached to the rod with tape and pulled into the car from the engine bay. Managed to get two further wires through by attaching them to the first and pulling them in too.
You need to remove the glove box to get access to the inside of the bulkhead grommet which can just be seen felt from around the top right corner of the fuse box. Getting down the near side of the car is childs play.
Hope this helps.
