3-3/8" SPEEDOMETER, 0-160 MPH, ELECTRIC, CARBON FIBER

Autometer electronic speedometers are designed to work with speed signal pulses between 500 and 400,000 pulses per mile. It should work fine with your 4,000 PPM signal.

Unfortunately they are only shipped with zero miles on the odometer.

Thank you for your question. You will need to use our GPS module P/N: 5289 in order to obtain a correct signal for the gauge.

Thank you for your question. Yes, 4789 as well as all our electric speedometers, is compatible with our 5289 GPS module.

Hi Rudy, thank you for the question. The 4789 Speedometer will adapt to your factory vehicle speed sensor, but it's not designed as an OEM replacement or direct fit for any specific vehicle. It will fit into a 3-3/8" diameter hole.

Thank you so much for contacting us. This gauge will work on your Jeep but will require the use of an electronic sending unit. There are a couple of different options. This one replaces the speedometer cable: https://www.autometer.com/hall-effect-speedometer-sender.html This one works off of GPS: https://www.autometer.com/universal-gps-speedometer-interface-module.html We used it in our recent YJ project which you can see here: https://www.youtube.com/watch?v=mwiVc3RiKy8 You also have the option of getting essentially the same speedometer with GPS already built in: https://www.autometer.com/3-3-8-speedo-140-mph-gps-carbon-fiber.html Hope this helps!

Hi Manoli, thank you so much for contacting us. The factory calibration on an AutoMeter electronic speedometer is 16,000 pulses per mile. You will see the current PPM calibration on the odometer of your speedometer for a second when power is first applied to the unit. Hope this helps!
