Electronic Speed Sensor for Speedo

I used a simple screw on speed sender listed for a 91 Jeep Wrangler, Dodge Dakota.
It screws on the speedo sendor from any Chrysler trans and has no mechanical output unlike most or the aftermarket ones that have the pass through leaving the output covered with a plastic cap or whatever.
   I got mine from a Jeep guy for like $10 used. new they can be had for around $50-60.
From 91 up most of the Jeeps use a non pass through speed sensor that goes in place of the speed output adapter. It just has a plug in the end for the harness. that one looks like it will also work in a chrysler trans, but, I have never tried it.

   My American runs Autometer Sport comp electric speedo, works fine easy to calibrate to!

I did have to make a heat shield as the exhaust was to close to the sender on mine. The speedo quit on a 96* day after heat soak for about 15 minutes in a parking lot. Made a simple metal shield to deflect the heat away and it has never happened again. I just hose clamed a small metal plate bend to have an airgap and deflect the heat.
