The side where your micro sd card is the upper side, the first number is your gpio pin number from the RPi itself (in ascending order) then there is the Broadcom number, and between the parenthesis as you can see are the matching Wiring Pi numbers.
First the left row from up to down:
1 3v3 Power
3 BCM 2 (WiringPi 8)
5 BCM 3 (WiringPi 9)
7 BCM 4 (WiringPi 7)
9 Ground
11 BCM 17 (WiringPi 0)
13 BCM 27 (WiringPi 2)
15 BCM 22 (WiringPi 3)
17 3v3 Power
19 BCM 10 (WiringPi 12)
21 BCM 9 (WiringPi 13)
23 BCM 11 (WiringPi 14)
25 Ground
27 BCM 0 (ID_SD)
29 BCM 5 (WiringPi 21)
31 BCM 6 (WiringPi 22)
33 BCM 13 (WiringPi 23)
35 BCM 19 (WiringPi 24)
37 BCM 26 (WiringPi 25)
39 Ground
And the right row from up to down:
2 5v Power
4 5v Power
6 Ground
8 BCM 14 (WiringPi 15)
10 BCM 15 (WiringPi 16)
12 BCM 18 (WiringPi 1)
14 Ground
16 BCM 23 (WiringPi 4)
18 BCM 24 (WiringPi 5)
20 Ground
22 BCM 25 (WiringPi 6)
24 BCM 8 (WiringPi 10)
26 BCM 7 (WiringPi 11)
28 BCM 1 (ID_SC)
30 Ground
32 BCM 12 (WiringPi 26)
34 Ground
36 BCM 16 (WiringPi 27)
38 BCM 20 (WiringPi 28)
40 BCM 21 (WiringPi 29)
