- I've got a 1991 GMC fullsize pickup that I am working on for a project.
- Since the engine is rather high performance, I don't trust the stock
- gauges and have complemented them with AutoMeter race gauges. This
- configuration with gauges tacked on all over the place looks pretty
- bad, and also puts the "good" gauges out of the driver's line of
- sight. So, I'd like to remove the stock insrutment panel and replace
- it with my nice gauges. The only problem with this scenario is the
- speedometer. The truck has rear-ABS which requires I retain the
- GM 1000 pulse/mile speed sensor which is mounted in the transmission.
- I have so far been unable to find any speedometer that can handle
- such a high frequency. Does anyone have some suggestions as to
- how to adapt a speedo to my configuration? As I see it, my options are
- 1) Find a speedo that works with the GM sensor.
- 2) Use an electronic speedo that will work with driveshaft magnets
- 3) Use an electronic speedo and build a circuit to scale down the GM
- sensor's output to what the speedo wants.
- Any input would be appreciated... I can't be the first person to
- have done this.
