Gauge Sensors & Converters

Everything you need to get your new gauges reading correctly – speedo converters, GPS speed sensors, fuel sender converters and sender adaptors.

Upgrading to electronic gauges on a classic car usually means solving a few problems: a cable-driven speedo, a fuel sender that does not match, or nowhere to fit a second sender. This collection covers all of them.

  • ESA-01 – converts GM Powerglide, TH350 and TH400 cable drives to an electronic speed signal
  • ESA02 – cable adapter for Trimatic, M20 and M21
  • SAAS GPS speed sensor – a speed signal with no connection to the gearbox
  • SAAS fuel sender converter – matches a wide range of fuel senders to your gauge

Frequently asked questions

GPS sensor or ESA-01 – which is better?

The GPS sensor is the simplest install and needs no gearbox work. The ESA-01 takes its signal from the transmission, so it also works where GPS reception is poor, such as in tunnels or sheds.

Will the ESA-01 fit a Trimatic?

Yes, with the ESA02 cable adapter.
