While diagnosing an overheating issue on my 96 bighorn plaisir 3.1td I noticed that I was missing an electrical connection from the thermostat housing and in its place is an allen key compared to my mates 95 Bighorn 3.1td which has the connection

Looking through the manual it seems to be the thermo-sensor connection for the QQSIII system, I really have no clue on any of this.
Would this be an issue for anything? The overheating or the reason why I have to glow the truck 2-3 times before it will start?
Any insight would be great, cheers
