convert t5 manual speedo to electronic?

[Roylerumble]

91 mustang t5 going into my CRII. Had mechanical speedo, but I'm going with a Smiths electronic speedo. I almost bought the Autometer 5292 pug in sending unit for Fords until I read that its only for their gauges. From what I understand, it needs to be a hall effect sending unit. What have others used?

Thanks!

I have a GPS Speedo and just plugged the speedo hole on the transmission. Mine is F5 but this is the company that makes them: https://www.speedhut.com/gauges/?catid=f19 These speedos work really well and acquire quickly.

The plug I used for the speedo hole on the T5: https://fortesparts.com/product/fort...ter-hole-plug/

Had a leak from the speedo hole before I installed the plug.

There is also a Speedhut GPS motor unit that can drive the original Smiths mechanical speedo with a cable. Closer to originality if that is important. Did this on my original 69 Lotus Elan so I could use the original speedo. Plugged the hole in the transmission.

The Classic instruments SN16F kit should work for you.

Replaces the cable output of the T-5 and has a 16,000PPM (pulse per mile output)

Your Smiths gauge is adjustable to 120,000ppm.

(See the note below the Smiths connection chart for the Red wire for the sender to get power to function)
"Note: Red wire connection is only required for
some 3 wire sensors. Connect to 12volts for NPN type sensors"
