I can understand his wanting to go to a cable driven speedometer. The cable driven speedometer in 87 to 91 YJ's are cheap to buy. The 92 to 95 electronic gauges are by far more expensive. But as stated the parts to convert to a cable driven speedo add up to more than a set of electronic replacement gauges.
If you want to go to a cable driven speedometer you will need the sending unit for the transfercase from a 91YJ. This part will be hard to find and probably expensive. Reason being, 91 YJ's were the only year with a cable driven speedometer as well as an electronis VSS sensor. You need the VSS;
VEHICLE DISTANCE (SPEED) SENSOR - ENGINE CONTROLLER INPUT
The distance sensor is located in the extension housing of the transmission (2WD) or on the transfer case extension housing(4WD). The sensor input is used by the engine controller to determine vehicle speed & distance traveled.
The distance sensor generates 8 pulses per sensor revolution. These signals in conjunction with a closed throttle signal from the throttle position sensor indicate a closed throttle deceleration to the engine controller. When the vehicle is stopped at idle a closed throttle signal is received by the controller. But, a distance sensor signal is not received.
Under deceleration conditions, the engine controller adjusts the AIS motor to maintain a desired MAP value. Under idle conditions, the engine controller adjusts the AIS motor to maintain a desired engine speed. The vehicle distance sensor input is also used to maintain speed control operation and a reference for the emission maintenance (EMR) light.
PM "cjinpa".. he might have a gauge set, tell him i sent ya..
I have a few gauge sets. Thanks for the reference Jim.
