i couldnt find any info on the electronic vss in the tacoma 00-04 electronic vss. What are guys who do tacoma swaps doing for a VSS to retain cruise. I found this info on the marlin crawler site which looks like it would be a 4hz/rev vss. The tdi ecm needs to see 1hz/rev. here is the info i found on marlin crawler per the toyota vss.
To troubleshoot the operation of the sensor, connect a 12 VDC power source across pins 1 (+VDC) and 2 (GND), and connect a multimeter across pin 3 (SIG) and the power source ground (or pin 2). With your multimeter set to read voltage, you will see two distinct voltage readings as you slowly rotate the shaft of our VSS: 0.07-0.08 VDC and 12 VDC. The lower reading is the nominal voltage (outputs at least this much voltage), and the 12 V reading is the pulsed output signal (which occurs exactly 4 times during one full shaft rotation).
The pulsating output signal (pin 3) will be the same as the input voltage at pin 1 slightly stepped down from internal resistance. If a lower voltage signal is needed, then use a relay, controlled by your vehicle's ignition ON power source, to activate a different power circuit whose voltage has been reduced through a resistor.
Any vehicle input voltage may be supplied and the output will always be the same as the input. The voltage drop due to internal resistance is about 5 millivolts (0.005 VDC) and may be neglected. For example, if you input 5.00 VDC at pin 1, you'll receive 5.00 VDC at pin 3 at four distinct positions per shaft rotation. Connect 8.25 VDC to pin 1, you'll get four 8.25 VDC signals at pin 3. And so on...
