Is this the voltage regulator?

I am removing the wiring harness from the engine bay of my '69 and have a couple of questions.

Question 1: The relay on the left fender next to the vacuum tank - is this the voltage regulator (it looks like it)?

Question 2: I am planning on ordering a new harness with the option of converting it to an internal regulated alternator. Will I be able to remove this regulator when I switch to a 1 wire alternator?

TIA.

Okay, then what is the other relay over on the right side near the A/C box?

I don't see a relay on my '69 on the right side (but I don't have A/C, either)......no relay by the blower motor, either......maybe someone else can help ?....

I did some investigating and it appears that the relay is somehow connected to the A/C controls, the wires go in thru the firewall and tie into the A/C control harness it looks as if Bubba had gotten to it.

Real scary! I'll post some pics as soon as I figure out how to post.

Relay on the driver's side is the horn relay as stated above. Relay on the passenger side is the blower relay if your car has/had air conditioning. Voltage regulator is built into the alternator - '69 is first year for the integral reg feature on Vette.
