Hi guys, a quick update on more trivial but still useful stuff. I finally got around to taking photos of the third brake light I'd fitted a while back. It cost £10 from Ebay and is a 24 LED light. The key selling point for me was that it was the right width (22cm total width, 18.5cm of which is the light) and that it was adjustable/ rotatable. I figured (correctly) that I could mount it against the vertical wall of the inside of the air intake with the supplied sticky pads then screw/ziptie it more securely. I wired it into the right hand side rear brake light feed and it works just fine. Much safer than those two reasonably dim brake lights barely 18" from the ground!
I also wired in a replacement air horn today - the old pancake horn had given up the ghost. I also managed to improve the earthing connection between horn push and the steering wheel. Looking at the whole frontend of the Chesil, I thought the best way to mount the horn was to place everything inside the car except the two horns which would be inside the front left wing. The hose is then fed through the body via a hole alongside the electrical feed for the headlught/indicator.
Given the way the existing wiring was laid out, I didn't want to strip the cable wrap all the way from the front of the frunk to the fuse box, so utilised the two existing horn wires to drive the relay, then placed the new relay next to the compressor. I ran out of black tape so temporarily wrapped it in red (horrible, I know, but it'll be sorted in short order) until I buy some more black. The horn is severely LOUD so when it is needed it will definitely wake the dead (i.e. White Van Man and oblivious mums in Chelsea Tractors).
Looks like it's now time to move onto the 'pretty' side of things and get the torn seat fixed and new carpet.
Funny how these cars generate such an impact with other drivers, compared to modern M3s, AMGs, 911s etc. Yesterday I pulled up to a roundabout and, whilst waiting for a gap, I actually had a guy stop ON the roundabout to wind down his window, give me a thumbs up and let me out in front of him!
