I have done a few 12v conversions and this is what i learned:
wire between tank sending unit only sends ohm resistance, the "feed" wire to the gas gauge needs to be dropped to 6v (use a ceramic inline ballast resistor or an electronical Circuit type 7806)
The electonic part is a bit hard to install (soldering required) but will provide 6v dead on, which will lead to a more accurate reading)
The charge meter does not care for 6 or 12v just wire it in on your 12v Circuit. (carefull though, if i recall correctly the charge meter originally provides current for gas gauge, instrument cluster bulbs etc) | | |
