power lock kit for 88 chevy

I have a 1988 Chevy C1500 and I have a "BF-A.A.A. Type R" power lock kit. The truck already has power locks, but I want to use the remote fobs from the kit to lock/unlock the truck. The thing is, I don't know how to go about wiring the stupid thing up.

Here is the diagram for the kit.

I assume I'll need this relay setup somewhere in there to even attempt to do this, but I'm not sure.

Can anyone help me so I don't blow anything up?

Here is information for the 1988 C1500 2 door truck from Audiovox.

Here is a suggestion...

The kit you have is to add the wiring and actuators that are already present in your truck.  If the current
factory hardware is working OK, then all you really need is a remote keyless entry kit.  ( Your current factory
setup needs the basic Type B (-) lock outputs.)  There are many choices available.  As an example, here is a link
to the offering from Bulldog Security https://www.bulldogsecurity.com/Products/453055507-model-ke1702-vehicle-keyless-entry-system.aspx
You can download the install guide.  With this kit, just locate the wires listed above and connect the keyless entry
kit output wires.  While it is possible to convert the actuator outputs from the lock kit you currently have,
the kit listed above would be a much simpler, cleaner install ( no extra relays, etc. ) and provide parking light
confirmation.

Soldering is fun!
