Wire Harness

[ELDERDADO]

Can any one tell me what this receptacle is for? (located behind carb) And why my mechanic felt the need to connect it to my alternator? What else goes into the other contacts? I believe it goes through the firewall.

If I didn't know any better, I would have thought it is for the external Voltage Regulator when using an earlier Alternator, that requires an external Voltage Regulator.

Are there any "vacant holes" in the inner fender opposite the Alternator where a Voltage Regulator could have been?

I too would say its for an external voltage regulator which makes sense since I believe we are talking about a 72 and the first year for the internal was 73.  The alternator in the picture looks like an internal regulator.

In 1972 Eldos had an internally regulated alternator. RWD didn't get one until 73
