Switches, connectors, control units in 72 A body

[72ScampTramp]

Ok so im new at this and building my first car. http://www.forabodiesonly.com/mopar/showthread.php?t=111522.

Now my question is im fairly new to these cars. Been working on my for about 3 years but the only one I have worked on. Looking for a list of switches, connectors, regulators I will need for the electrical system. I do realize this is a odd question but would like to buy new ones. I do have a wiring diagram. Also going with MSD ign, and Mallory Dist. No AC or heat. Failed to mention I have a 72 harness stock and also a 12 circuit aftermarket harness. Haven t decided which to use.

For the harness, for me, would be a no brainer. Put in the 12 circuit, get rid of the bulkhead connector (or run wiring straight through) and convert the ammeter to voltmeter

Ideas on ammeter to voltmeter, a simple project:

On mine, I used a "used" Painless harness I got cheap, that someone had abandoned a project. I left such connections as the wiper connector in place in the bulkhead, and ran other wiring through the vacant connector holes

Mine ain't all the pretty, but I used a Voyager relay box, and you can buy new ones made by Bussmann which you can configure the way you want, for the underhood loads, ignition/ charging, fuel pump, high and low beam, and an extra for security, as well as a couple of spare sockets.

This one mounts very nicely to the front fender apron between the battery and washer tank

Some of this will also depend on whether you want a trunk mount battery, and plan on ever showing up at a dragstrip, as you must have certain safety 'stuff' in regards to a trunk mount battery

I actually left the amp meter in mine. but will run an aftermarket gauge. Now if I understand you correctly you used the relay box to cover and supply your under the hood. Does this take pressure off the rest of the system?

Here i a list of a few things I need. Anything else?

Yes a combination of things

Relieves stress on the ignition switch, which now continues to directly switch heater, wipers, radio (just the low power control head) and warning lights / gauges.

The heavier ignition/ regulator loads and fuel pump are run by relays

The headlight switch/ dimmer switch now simply turns on relays

So all that stuff that normally went through the bulkhead is now contained under the hood.

In addition (see the Mad article)

http://www.madelectrical.com/electricaltech/amp-gauges.shtml

The only heavy wire going from engine bay into interior is now simply a battery feed, and much of that has been lightened by the relay box

The heavy charging current no longer goes through the bulkhead connector, a single no6 wire direct from alternator output to the starter relay battery stud.
