Accenta to delta bell plus box?

Hi
I have an accenta G3(i think) the bell terminals are:

+13 Red
Scb (a) Black
Bell (-) Blue
scb (t) yellow
Strobe (-) green

White cable is not connected.
There is a resistor between bell + & -.

I'm trying to connect this to a deltabell E/plus which has terminals:

T T Eng hold STB BELL +-

I'm guessing I need to
1.change jumper3 to Off (SCB)
2. Change jumper 4 off (right pins) & applied (left)
3. Jumper 8 (left) battery.

Wires:
T --- scb(+)
T --- link to (-12 On bell)
ENG --- nothing
STB --- strobe(-)
BELL --- bell(-)
12+ --- red
12- --- scb (-)

Is this correct?
