I've always kind of enjoyed the wiring part of building a car (I guess I must be a bit masochistic..?). That is, until I built my Track-T...

Working under the dash in such a tight space is pure torture! I had to remove one of the seats and lay down with my head under the dash and my legs over the back of the body. That was tolerable until about the third time I needed a tool or piece I had forgotten to bring under there with me. Then I had to climb out, get whatever, and climb back in again... and my fuse box was under the seat!!! On top of that, I pre-wired the back side of the dash (gauges) so all I had to do was a couple of connections and wire the brake light switch. I can't imagine the Hell I would have gone through if I'd had to do all that wiring under the dash. If you haven't already mounted the fuse panel and started running wires, you might want to think about it a bit more. Even with the fuse panel under the passenger seat, I still had room for a pouch to hold a sweater, rain gear, some shop rags, a zip-lock bag with registration and insurance card, and some spare fuses and ignition module. I got rained on a lot, but none of that stuff ever got wet.
