That is the connector you need to use, all the feeds you need are in there, just cut the plug off and connect the new loom to it.
or you can wire the new loom to the fuse box and connect directly to the dash display for the gauges.

Green-Tacho- (Car loom Green)

Blue-Engine coolant temperature gauge (Car loom brown/white)

Brown- Oil Pressure (Car loom light brown/green)

Red- switched Ignition feed (Car Loom Black)

The fuel pump relay fuse has a blank output pin, connect to the car loom Black/Red OR to the fuel pump directly, (We advise the use of an inertia switch if running directly)
