stuck on the side of the road no start

Same happened to me when driving the 64 Valiant I just bought home. Found no spark. Rather than trouble-shoot the wiring on the side of the road, I just ran a jumper wire (never leave home without some) from the battery to the upstream side of the ballast resistor and drove home fine (actually I first hooked to coil+, drove 5 min, then started missing at higher throttle, coil real hot, so hooked thru ballast). When I got it home, I pulled the key switch out and found no factory connector and a bunch of spade terminals, with several coming loose and/or shorting.
