Made a bit more progress with the car over the weekend. I wanted to do the last bit of wiring and get the steering wheel buttons wired up. First up was to paint the bare panel, here's a photo of it in primer:
Then I had to take the coiled wire and and wire it up to the switched. Each core wire is very thin, I think it's only rated for 250mA, so I soldered it to the pins on the back of the buttons. I then used boots to cover it up and offer a bit of protection. Here it is wired up:
I wanted a fixed mounting point for the connector between the coiled wire and the main loom to make sure it stays out of the way of my feet, and also to provide strain relief so it doesn't pull on the small wires. I made a small, rectangular plate that is bolted up with the steering column:
After faffing around wiring in the DTM connector, you end up with something like this:
Then I painted the panel black so it's a bit more subtle and hooked everything up.
All seems to work well. I have headlight flash and one-touch wipe working. The other buttons are for pit-to-car radio (still needs to be wired up) and a pit lane speed limiter that needs mapping in.
I'm due to race at Silverstone GP in August so need to get the car ready for that. The Odyssey race battery I've got still struggles to start the car after the new wiring loom. I'm wondering if it's just not big enough, even though it's brand new.
