if its on the astra loom then no need for it as you use the nova starter and charging loom

it is the constant live that needs connecting as i said in the second post

it has a thick red wire that comes out of the right hand side of the injector block and goes to a black plug, one side goes to the fuel pump relay, the other side goes to constant live, if im not mistaken originally it was connected to the astra starting cables, which get ditched in favour of the nova ones

I just took mine back through the loom block, crimped a round terminal onto it and connected it directly to the battery,

you need it, you ditch the astra starter and charging cable and use the nova one

those are for guages/unneeded etc, the engine will work fine with the constant live red connected, the switched live black connected, and the fuel pump relay (red/blue from the fuel pump) connected to the fuel pump
