not sure exactlly which red wires you mean. if you mean the red 5v pins then they just have a short wire (4 inch long) with a plug each end going from one 5v pin to the other 5v pin and not connected to anything else. and on my loom theres three other wires, blue, green and tan and they went to the pins with those colours written next to pins. other than that, (i pulled loom out of box) and cant find any other red wires that go to fuel,temp etc gauges. let us know how you get on. im far from an expert but do have dash and loom out at minute and can have a look for you.
