Bought a DoCooler remote lock unit for my sons 2003 F250 SuperDuty with no factory power locks. Trying to hook it up, but clueless on whats needed and cant seem to find a decent wiring schematic. Not sure if I need relays or not and how they would wire if so...
Any help is much appreciated. Heres a link to the unit I have>> https://www.amazon.com/gp/product/B006QH9C5A/ref=ppx_yo_dt_b_asin_title_o00_s00?ie=UTF8&psc=1

I don’t see actuators in the link you posted. This unit could be added to a vehicle with power locks and no keyless. If there is no existing power locks you will need to add that first before keyless can work. Either purchase a door lock actuator kit or return that unit and purchase a keyless kit that has actuators included.

The truck already has power locks, just not equipped with factory keyless. Just need to know if I need the relays and how they'd wire.

Relays are built into the unit. Post the instructions or a link to them.

You need to determine if you have type B or type C locks by testing at the drivers switch or in the door jam. Check note #2 on the bulldog wiring diagram and also there are photos at the bottom for reference on both types.

Once you test and figure out the type you can wire it as shown in the diagram from the keyless system. Close signal means lock and open signal means unlock. Both yellow and yellow/black wires will either be going to constant +12v or to ground depending on which type system you determine that you have.

might also be 5 wire locks if it didnt come with a key fob originally. Negative locks if it did and the GEM module will fall asleep after 10 minutes of the truck setting, to test roll the drivers window down lock the door with the door open from the factory button on the door and shut the door, wait 10-15 minutes reach in and try unlock. If it doesn't unlock the GEM module has to be woken up before any keyless entry will work

33 years as a installer now just a retired old guy. Favorite thing to install/topic are remote starts/car alarms. Stop using test lights!!!
