I have nearly finished wiring the digi dash into my corsa, but for the Fuel guage/warning light, there are TWO wires that are blue/black, and I have the same on the corsa loom.
Do these all connect at one point? ie. take both wires from Astra loom and join (asif to make one wire) then do the same with the corsa loom, and then join the looms together.
Or does each of those wires have a seperate purpose?
