I'm back. Please forgive me for the long delay. I had computer trouble for a couple of weeks. Also, I asked Ken to post a reply for me, but I neglected to notice I never posted the list of wires I wanted him to refer you back to. I have them below now.
As near as I can tell, the purple wire you're looking at is in spot C5. If I have that right, it's one of the ignition 12-volt feed wires to the ignition switch, but it isn't related to the starting system. That is likely for things like the heater fan or wipers.
Stick with the yellow wire in terminal D1. That one will have very low current flow, so any wire you have will be fine, and the current flow is only there during cranking. If you use an ignition feed wire instead, you'll need a switch and wire size that can handle much higher current all the time. It's more likely for a switch in that application to fail while driving. That would leave you sitting on the side of the road.
As for connections, the only acceptable method is to solder the splices, then seal them with heat-shrink tubing. Wire nuts do not belong anywhere there's moisture or vibration. Butt connectors do not seal out moisture or salt. The best heat-shrink tubing has hot-melt glue inside to do a much better job of sealing out moisture, but it really isn't necessary under the dash.
