Hei Distributor

[67-72lover]

Hello I have a 71 chevy c10 with a 350 someone has put a hei dist in the truck prior to me owning it. Ever since ive owned I keep buring through ignition control modules every couple of months. Can any point me in the direction what is causing this please. I was told that the wire coming from the junction block to my distributor originally was a resistor wire needs to be changed over to run 12 volts at all times looks to be changed but am gonna do it again to make sure. Can i just splice as close to the junction block and as close to the connector on the distributor as possible and be safe?

Thanks for the help
