SPAL Power Lock actuator with Viper 350(3105) relay wiring question

I recently purchased SPAL USA 37000148 Two-Door Power Lock Kit for my 280z.

Also I purchase Viper 3105V alarm kit.

SPAL 37000148 kit comes with 2 actuators and 5+2 wires harness.

Also I purchase the switch.

The wiring harness is using 5+2 wires. Since I'm planning to install speaker, power window kit, I would like to reduce the number of the wires.

Therefore, I prefer to get rid of original wiring harness and just run 2 wires for the door lock. When I research the12volt.com mentioned I need 2 relays to operate lock/unlock function.

I'm not sure whether I need total 4 relays (2 per actuator) or just one set (2 relays) only.

Here is what I'm planning to wire actuators, switch, and viper alarm.

Could someone give me advice?

Thanks in advance.
