Step 34 in the instructions I sent you:
a) Yellow - Wideband input. Connect this to your wideband analog output
b) Grey - Switchable tables. Connect this to a ground (through an on/off
switch) to switch between VE/Ignition tables.
c) Brown - Launch control. Connect this to a ground (through an on/off switch)
to switch launch control on/off.
d) Violet (purple) - Boost control low/high. Connect this to a ground
(through an on/off switch) to switch between low/high boost tables.
e) Green - Boost control output. Connect this to a boost control valve. The
other wire of the boost control valve needs to be connected to a switched and
fused 12V source. A 5A fuse is recommended.

You will need to convert your engine (injector) harness to sequential first. I would advise that you first get the car up and running as-is, then I can you give complete instructions on how to do it.

I've already sent you the instructions, make sure they are not in a spam folder etc. If not let me know and I'll send them again.
