Why can't I bypass the inertia and oil pressure switches on my fuel pump?

Hi Everyone:

Thanks for all the useful information. Life and cold weather got in the way for doing much on this until the last couple of weekends. The fuel pump was bad, but getting that working didn't really solve my problem. So, I added a bypass. Looking at the circuit more closely I decided that I should not do what I originally suggested because it would apply 12V to the wrong side of the Inertial Switch. I don't know if this is bad, but I did not want to take a chance. So, I ended up with something a lot more complicated. Part of the reason for this is that I wanted to use the A/C switch, since the A/C in the car is bad, and because it is a toggle switch, I wanted to add a lamp. The only thing the bottom relay does is light the lamp. This works as it should and the car started on the first try. I hope that this wasn't a fluke......

Wow:

A real triumph radio. Can you hear it with the top down? Electronics of that vintage had flea power to drive the speakers, so I yanked it and installed some up to date electronics. At least I can hear the radio when tooling around town.

Yes, the original radio is still there. It does not work very well and I use a bluetooth to FM transmitter to listen to my phone. I can't hear it when the top is down. I am eventually planning to replace it with I modern radio if I can find one that will fit without cutting anything. Any suggestions?
