318, E-Coil, GM ignition module, Chrysler Distributor...need wiring help!

I've been reading all the threads, but can't seem to find a solution. I am running an E-coil, GM 4 position module and a Chrysler distributor. It fires right up runs perfectly with coil connected directly to the battery or starter relay hot wire. Obviously I cant keep it wired this way, as the key wont turn it off. I understanding the E-Coil needs a full 12V, I ran a relay so the original ignition wire would activate the relay. I got it started after several cranks, but clearly needs more voltage/amps to the coil. I'm scratching my head as I used a 10awg wire from the battery to the relay, and 10awg to the coil. I tried a double ground, a different trigger for the relay, and even tried another relay to make sure it wasn't defective, but no luck. I'm not sure how else to get that much voltage to the coil without cutting up the harness...which I don't want to do. Any ideas? Maybe my 30/40 amp 14V relay isn't powerful enough???
