Ok, this is probably second nature to most of you, but I have a smple gauge wiring question on my '62. It's my first time putting aftermarket gauges in and I'm trying to keep it simple. I have an electric temp sender gauge, Autometer brand, that I'm wiring up. I have the sender wire hooked up to the S terminal so far. I need to find a place to hook the gauge up to a "switched" 12v ignition source. I really don't want to splice into wiring if I don't have to. What is the best, simplest, safest place in the factory wiring to hook it up to? I noticed the fuse block has some spade style connectors- I included some photos. Is that a good spot? Or? Also, for grounding it, the instructions say the engine block. Can I just run a wire screwed into the dash frame somewhere? Thanks for your help.
