hi, im putting my 4x4 sapphire back together but i cant remember where the other end of the black negative battery cable goes, also should the be a wire that comes out of the injector loom between 3rd and 4th back that bolts behind one of the plenum chamber screws. there are also 2 push on connectors and for the oil pressure switch on the block and one by the blue sensor on the head, is it the big push on one that goes on the head and the small on the oil pressure switch. please help. Cheers Ash
