Swap sub and dash gauges?

[johnmrson]

I had LPG fitted to my 80 series a while ago and the fitter wired the LPG tank to the overhead sub gauge although I asked him to wire the LPG tank to the main tank gauge in the dash.
Does anyone know how to swap the feed between the two gauges?

check the FAQ section on subtanks, I'm pretty sure it's there.
