bft 2b kit wiring

[Sav]

Hello,

The earth wire would wire into your ground symbol or straight back to the main earth in if no ground symbol is available.

Ground symbol- http://www.safetylabelsolutions.com/Eart...p_268.html

just got the LUX 2B KIT from the hydraulic rams there are 4 wires black, blue, brown & earth, on my wiring diagram it shows that 4, 5 & 6 are used. where does the 4th wire go to and am I right saying that blue goes to number 4, black to number 5 & brown to number 6

any help would be appreciated
