This is a prime example of where the MAD Electric bypass is mandatory. It is the simplest and probably the most economical fix there is. Here is a link:

I did this fix on my 1966 Chrysler 300 and on my 1966 Plymouth Satellite. The wiring harness and bulkhead connect along with the fuse block were all replaced and a new and complete wiring harness for the engine and the dash was bought and installed. There really is only one manufacturer for my money when it comes to the harnesses. That is M&H from Year One. I know the price is high but the fitment and plug n play aspect makes it really easy to install. If you want a PITA set up then the Painless offering will give it to you. DAMHIK....Evans is OK I guess but I have heard nothing but negatives about their products and customer service is minimal at best. I run a high amp alternator and wired in a separate powered buss for my extra gauges and stereo. That is easy to do and only requires an additional fusible link to keep the buss from overloading. The buss also has individual fuses for each accessory wired to it. Pretty slick set up if I do say so myself. But from the looks of things on this car, it needs a complete wire upgrade and install. If you need more help and info, I have a ton of info and experience with this stuff and am here to help....cr8crshr/Tuck
