Need help on the circuit drawing

[Poortraveller]

anybody know what this drawing is saying?

 

wat does the square with number 86, 85, 87A, 87 and 30 mean?

Look like a familiar place in JC. The plan is to illegally tap the signal from 85. The honk is a red herring.

i think its a relay switch....just a guess.

[Poortraveller]

wat is a JC?

 

gosh ... i can explain in more layman term

[Poortraveller]

if it is a relay switch ... where can i get it from?

[Clubace]

the obvious place would be sim lim tower.

 

Ask around in the forum.
