Will this fit a 1994 V6 Mustang?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.Date published: 2018-07-30
Hello - Will the #4789 work with a 1990 Jeep YJ 4.2L? Do I need a sensor as well? Thanks.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!Date published: 2018-06-13
Hello, I'm using this #4789 with a Holley ECU. What would be a proper "pulse per mile" setting that the Holley uses for speed signal output ? I used 4000ppm like f-body Camaros use stock, but speedometer wouldn't calibrate.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!Date published: 2018-06-05
