RRR,
Maybe I should have been more specific with my poor/corroded connections comment. I meant any joint that is not soldered: removal plug/sockets, spade lugs etc.
There is no comparison using a HEI dist. With HEI there is NO bal resistor & the 4 spade lugs; there is no Nichrome wire that can burn out as in the Mopar bal res. The HEI pick up plugs directly into the module, so one connection. On the Mop ECU pick up, there are two connections: dist plug/skt & ECU plug/skt. The HEI coil has 3 connections, harness from the module to the coil & wire from the ign sw. The Mop system has 5 connections, ign sw to bal res, bal res to ECU, ECU to coil.
If you are using the HEI module you can mount/install it such that it has less connection points than the std Mop ECU set up.
