Quick question about Ignitor units

[BASS-TREBLE]

This item on ebay may be suitable for me, can someone tell me if it's a single or double pickup from the part number? http://cgi.ebay.co.uk/ws/eBayISAPI.dll?ViewItem&item=350273263774&ssPageName=ADME:X:RTQ:GB:1123

It'll be a twin trigger. The FZ750 had 2 coils and 4 cylinders.

Edit: Found a pick-up schematic (http://www.bikebandit.com/houseofmotorcycles/showschematic/m7191sch210345) on BikeBandit (http://www.bikebandit.com/)
