Re: A question about gmc 1969
The down side of going electric is the loss of accuracy. Every connection adds resistance and that affects the guages reading. It is the same issue with the factory water temp guages. That is unless you step up and go to a late model 5 volt PWM sensor and guage set up. But then you will need some sort of computing power.
That seems like a lot of effort to avoid a maybe leak that most likely could be avoided by cutting the factory steel tubing off at the old ferule and correctly installing a new ferule. But that is only my opinion.
