Judging by that bundle of split loom in your picture, if that is ALL of the wiring that was supplied... If there is no relay next to the power lock in the cover, then I would have to say no relay was supplied. The wires are already in split loom which is very nice. You can run this up into your cab, hopefully through an existing hole of which there are several. Then under your dash and to the BCM wiring to get at those power lock signals for your relay(s) that you might need to buy.
