Hacking the signal box is the same as you've done during the Cayo Perico Heist and many others. You need to link the numbers on the left to the symbols on the right to get the target number at the top.
But linking the numbers to the symbol isn't random. There is actually an easy way to solve this. You're basically multiplying the numbers. Each symbol represents a multiple. Remember the following:
Once you've successfully hacked the signal box, you will get one of the locations where you can steal the Police Maverick from.
When you get to the hospital, you need to park slightly awake from the destination. For some reason, the cops easily detect you when you get close enough with a vehicle.
Be careful of the security cams as well. Watch out for their cones of vision. Avoid them and continue going up. The pathway to the top is linear, so you don't have to worry about navigating too much. Just avoid the cops as you go up.
However, a much faster way would be to land on top of the rooftops next to the Maverick and steal it. But that is if you're landing on the rooftops directly.
If you try to reach the Maverick while already detected by the cops from the get-go, it will be very difficult as the cops are really aggressive. You will keep dying before you can reach the Maverick.
Whenever you're climbing ladders, keep an eye out on your minimap to keep track of the cones of vision of the security cameras.
Speaking specifically about St Fiacre Hsopital, stick to the right side of the rooftops and continue moving forward.
You will eventually reach a final set of ladders to your left with some cops and another security camera to your right.
As soon as you get inside the Maverick, you will get a 3-star wanted level.
Fly high into the air and avoid the cops until you've lost them.
Planning Work 2: Tactical Gear
In this planning work, you must steal a riot van containing tactical gear. The riot van is in a lockup, surrounded by a lot of enemies.
First, take out all the enemies outside when you get to the location. If you have an Oppressor Mark II, you can quickly take them out using your homing missiles.
If you have an Armored Kuruma, that can also keep you safe while you take the enemies out.
When you enter the lockup, take the stairs to the lowest level and you will find more enemies guarding several riot vans. You need to check each one of them for tactical gear.
If the riot van has tactical gear, it will have metallic securing. The one without the tactical gear will be empty with nothing in it.
Deliver the riot van to your Salvage Yard to complete the mission.
Planning Work 3: Disrupt Equipment (Optional)
This optional mission can help make the final robbery mission easier. It is a timed mission, so we recommend using either an Oppressor Mark II or a Buzzard.
Completing this mission will essentially decrease the number of police officers inside the police station during a robbery.
First, you need to make your way to the LSPD lockup and destroy the first set of equipment. When you get to the lockup, you will find some cops outside.
Take out the cops inside and use explosives (such as a sticky bomb, grenades, or an RPG) to destroy the LSPD equipment.
Once destroyed, you need to find the location of the rest of the equipment. You can do this by looking for a clipboard inside the lockup.
After getting the list, you should still have around 7-8 minutes to get to the rest of the equipment. There are three more locations where you must destroy the LSPD equipment.
With all planning work complete, you are now fully prepared for The Gangbanger Robbery finale.
