Hei /6 won't shut off?

I have converted my slant to Hei using Echlin TP 45 unit. Solid 12V from Bat (fused) into 4 prong Hella relay. Trigger from 12V live ignition on. All earth's give good continuity to block/body? All proper new wires used, soldered ends with good crimping on terminal connectors.... I have read 99% of articles on the web for research and preparation prior to conversion.

She starts and runs great, but will not shut off with Ignition switch?
