wiring check

moparfanatic56 said
I have all new m&h wiring harnesses through out the entire car. I put the battery in connected the red power wire from the bulkhead and a power wire from the battery to the starter relay on the inner fender. I currently only have the headlights and wiper motor that are functioning and nothing else no taillights, brake lights, dome light, side markers etc.

It would seem that there is a mismatch with the interior connections. Whether the mismatch is with the bulkhead connections or the key switch, is the question.
This assumes a standard wiring harness, not a option fleet or similar modified arrangement.

According to my cheet sheet below for '72, this should provide power to the headlight switch and items connected to the 'always hot' fuses in the fusebox. This includes parking lights, horn, and dome light.

If you have a voltmeter or test light, check the feed connection in the fusebox (12 or 14 gage red with white stripe).
Normally wipers get power from the switcxhed 'accessory' feed. Will need to check that with the '72 FSM

Although not relevant to your immediate problem, this terminal is not a great choice for the battery feed.
