Getting in under the dash is always a tight spot to work, is there a better place along the line to put it? | | |

A ground lead attaches to the cluster mounting screw. The +12 lead connects to a stud ... not much choice in mounting!
There are other V reducer designs available. They can go into almost any location you choose between the fuse box and the gauge.

I'll have to wait until it comes in the mail to see what I have to work with, it's the EL311 version from Carters trucks.
thanks for the input, I'll probably get back to this thread when the mail arrives. | | |

The unit your getting can go anywhere on the line between the power source and gauage. Unfortunately under the dash is about the only place to put it and not show. It also gets very hot and you have to make sure it not touching anything that can burn. You could crimp on a extra piece of wire that leads to your gauge to give more length. That should make it easier to work with. Cecil... | | |

That Jim Carter voltage reducer is a one amp Runtz voltage reducer. It is often specifically recommended for the negative ground gas gauge. I put one between the positive lead and the post on the gauge (one end of the reducer directly attached to that post) and I have not had any problems with heat. I don't know much about electricity but I bet there is very little current going through the gauge (and thus very little heat being dissipated by the voltage reduction).
[added later: I was not clear about stating that on my truck the positive lead is attached to the Runtz resistor and the other end of the Runtz resistor is attached to the "hot side" post of the gas gauge. The other post on the gas gauge is for the lead to the gas tank sender unit.]

I have a EL311 at home that I never used because I decided to leave the truck 6V. Your right about not worring about the sending unit.
