I have been following the instructions on the attached feed ( > Fuel gauge function - b < ) about stripping down an MGA fuel gauge. Towards the end, I realised that all his wiring is for a negatively earthed car and my Healey is positive earth. Does this make any difference? Will all the values be the same if I just reverse all the wiring?
