Not enough info on programmer to be 100% sure but best guess

Code:
CS#   <-   CS
SO    ->   MISO
WP#   <-   1
VSS   <-   GND
SI    <-   MOSI
SCLK  <-   CLK
HOLD# <-   2
VCC   <-   3.3v
  ^         ^
Chip       Prog
Warning - Chip is 3.3v but programmer pins are 5v according to reviews.

CS polarity may need inverting
Prog pins 1, 2 & 3 are general purpose but use depends on programming s/w and no info to hand.
