So I have purchased the HD Voltage reducer from Jim Carter parts. My questions is where did you locate yours? Did you put it up under /behind the dash or by the sending unit in the Tank? Any and all opinions will be appreciated. Thanks in advance!

A voltage reducer to drop the voltage from 12 volts to 6 volts, I assume?
The reducer that JC sells for the fuel gauge part # EL110 "light duty" is 22 ohm, 10 watts.
The reducer that JC sells as part # EL135 "heavy duty" is 50 ohm, 50 watts.
If you purchased the EL110 then instructions says, "Attaches to positive wire that leads to fuel gauge."
JC is short on details but the other end (lead) of the resistor would connect to the fuel gauge.
