Pink salmon run times differ from system to system, but all tributaries of the Fraser River usually have similar run times as they all have to pass through the Fraser River.
The Seymour River and Squamish River can be good from the beginning of August. Cates Park in Deep Cove, where Indian River's run passes by, will see some fish around the same time too.
For the Fraser River, the peak of the run usually occurs from the last week of August to the second week of September, however the entire run lasts from early August until the end of September. During the peak period, you'll find them comng through in large numbers at any given incoming tide in the Tidal Fraser River. For best quality of pink salmon, target them in this section of the Fraser River as they are very fresh from the ocean. Chilliwack, Stave, Harrison Rivers will see their runs of pink salmon arrive around the end of August.
The setup that I personally like to use for pink salmon is a 7 to 8.5 ft spinning rod rated 6lb to 10lb test. The spinning reel shouldn't be too big, enough to hold 150m of 8lb test mono. The main line is tied directly to the lure that you wish to use. Pink is the preferred colour by most anglers but it really doesn't matter what colour you use. A plain silver spoon will catch just as many fish if you have the retrieving speed and action dialed. 1/4oz is the ideal weight for your lure.
