Distributor question?

[Grajeda]

Here is another one to throw at you. this truck came without the stock distributor, in its Place is a HEI distributor. The white resistor wire (cloth wire) that comes from the firewall to the orig. coil has been cut and spliced with a regular wire (not sure what ga.) which now goes to the HEI distributor. I want to replace the existing wiring harness with a new one, will there be a problem with using the new harness resistor wire with the HEI distributor? I guess what i'm asking is does the HEI need a special type of wire different than the resistor wire which will come in the new harness? Has anyone used the HEI in this fashion?
