1997 Esprit V8 - Boost gauge
I have a V8 turbo and posted recently here about the fuel pump.
While working on the fuel pump, I noticed a short black wire not connected to anything (attached photo).
The boost gauge (in the dashboard) does not work, so I thought this wire may be related to the gauge.
i glanced through the owner's diagrams and found the approximate location of the pressure transducer (sensor), and thought the unconnected wire would be the culprit.
I looked for the pressure transducer and found that it has two wires connected to it. It sits near the ECU.
The one unconnected wire is located near the firewall and hangs loose above the fuel pump.
1. What could the unconnected wire be for?
2. What should i check to fix the boost gauge?
Thank you for your time and advice
