dynamco cyclops s35i query

i have been restoring a vintage car and just purchased this system. i think that the same system exists rebadged under other names such as dynatron d355, night vision nv5000, d355 and p355.

it is basically an upgradeable immobiliser with multiple input possibilites. it has all black wiring coming out of the brain box which is apparently a legal requirement where i live. the unit is remote controlled.

anyway, i have successfully wired in most of the wires (eg to central locking, indicators, door switches etc etc) but i am a bit confused by the actual immobilisation circuits. The unit has two independent 30amp immobilisation circuits that i presume are just switches connected to relays inside the box. Only problem is there seem to be too many wires!

each circuit has 2 wires coming out of the box but these mysteriously split into two each. giving a total of 4 wires per circuit. if it was 2 wires per circuit i was going to wire one into the starter behind the ignition (key) and the other into the dizzy low tension circuit. but im confused by the four wires... why do these wires split into two?

any help would be gratefully received! this looks like a great online resource.  i can take pictures of the rather unhelpful diagram that came with the unit if it would help. and i also have a full wiring diagram for my car (bmw 2002 1971)

thanks
