The pin out diagram I mentioned also has a picture of the connector.
However, I would suggest you get power directly from the fuse box. There are three aftermarket accessory port in the instrument panel fuse box. They look like half of a fuse slot (i.e. only one pin instead of two). They are labeled BATT (constant battery power), IGN (ignition switched power), and ACCY (switched power that is also available during RAP operation like the radio). They are protected by 15 amp fuses but you should use your own inline fuse anyway - probably much smaller than 15 amps.
