You're right, grounding the negative side of the coil (as is done with the stock interrupt) can damage the HEI module.
However, you could use a relay to interrupt power to the HEI. Run the HEI power feed through the relay's N.C. (normally closed) set of contacts. Hook one side of the relay's coil to power and the other side to the OD interrupt wire.
