TBI fuel pump relay wire colour order

Hi, brought the car not going and working through things. Found the wires for the fuel pump relay connector loose or maybe not connected so replacing the unit. Are the wires in the right order? I’ve looked online and in the Manuel and come up with various options and opinions. Car appeared very original but found some strange things which would indicate someone has had a go at fixing it previously.

Cheers

Re: TBI fuel pump relay wire colour order

Looks correct. My car had the same thing going on where the wire was exposed at the relay connectors as if the wire was stripped of its insulation too far down. seems to be a common occurrence

copied this from another thread
E=orange 12v fused power
C=dark green/white ecm driver
B=blk/whit ground
A=tan/whit oil pressure switch
D= red test wire
