What relays have you added?

Thanks for the info. Was wondering where you purchase your bosch/tyco brand relays. I went to the local parts house yesterday and ask about mountable relays but all he found was the ones that plug into a relay box as most cars have today. Also how many terminals are on the relay. 4 or 5? I thought there was a ground, trigger input, 12v feed and 12v to accessory. all of his were 5 terminal.
