Intermittent Ignition Issue [66 Valiant /6]

No idea what this means, can you post a photo?
The one you sent earlier, the one with 4 terminals (BAT, IGN, SOL,GRD). I switched it back to the original two tang one with the screw connector and the tang. (FLN, IGN) and it still works. Definitely not the relay then. Problem lies elsewhere. Wiring has definitely been fucked with, Many previous owners and 60 something years on this earth haven’t been kind to it. Pics might be low resolution so wiring diagrams are available here - Wiring – MyMopar
