I have on several of my old Mopars. One needs to do so for any modern ignition which tosses the ballast resistor. I connected IGN and IGN2 at the key switch terminal, using spade jumpers so I didn't permanently bugger the factory wires. It is easy to release the pins w/ a thin screwdriver, though I use the correct tool for 57 terminals. I repurposed the IGN2 wire for my AC compressor (previously run thru a hole in firewall, dealer-AC I think) since bulkhead terminals are limited and valuable. Easier is to just jumper across the ballast resistor. No problem for me using the smaller IGN wire since it turns on an underhood relay to provide IGN power.
