Ford Transit MK6 LWB minibus after market alarm help

[Xbfreedom]

I'm sure this has been covered but so many different topics on it. Wondering if anyone can help?

Just got a Hawk HA-240Lite alarm from eBay. I'm pretty confident with wiring and soldering. Just need a few things clearing up. Does my van have negative or positive door input. I've found the door pin by driver's door and have a black wire and a black/red wire which one do I use?

Also wire location and colour for left hazard light and right hazard light?

Many thanks.
