alternator question

i hate asking questions but i cant get any decent information just higher voltage then mine,
i have a current performance engine harness and a painless wiring chassis harness,
i just installed my autometer gauges now the issue is im charging at 16 volts then with the lights on its reading 14 volts
am i being overly paranoid?

brake lights

okay this may sound very silly so lets get that out of the way,
im almost done wiring my car completly,
im using a painless hot rod chassis wiring kit,the last thing i have to wire up is my brake and marker lights,
can someone post a picture of how the lights light up i guess haha,
i just wanna make sure i have them hooked up right,
sorry if this sounds dumb just to others id like the lights to look stock

new to racing suggestions

my name is Robbie, from edmonton canada we only have one road course close by but a 1.2 mile autocross track that i fell in love with
anyways i bought my buddies old 1995 camaro z28, just got the car completly rewired and running this last month
im mostly looking at autox and then if im able to trailer it to road courses south of the border
its a lt1 6speed car with deleted cats and flowmaster 60 with 3inch single pipe and a centerforce clutch,
has h&r springs, hotchkis sway bars front and rear, hotchkis panhard, hotchkis front and rear arms,
i have a set of 18inch oz superleggera wheels on it and plan to put a set of c6 z51 wheels on it for weight over the oz's
over winter i wanna upgrade to c6 z51 brakes on all 4 corners,

im kinda a minitruck 80hp kinda guy and figured this would be the best place to get whatever kinda advice i can
Thank You
