there is no wire it is controlled by a sensor.
It simple they did not make a tacoma in 1990.
where is the tach wire en Toyota tacoma 1999 4 cilinders
If you are referring to the sensor for the speedometer and the computer it is a 3 wire plug located on the tailshaft of the transmission
The speedometer sensor is located directly above the tranny end cover (toward the rear) on the right side of the bike. You'll see the wire leading from it.
The high beam wire on the 2004 Toyota Tacoma is red with yellow stripes. You can use a test light to determine which wire is active when the high beams are on.
Blue wire is for a tach I believe
The positive wire for the 2005 Toyota Tacoma tail light is red with white stripes. The negative wire is white with black stripes.
If it's a 1992 V6 4Runner with an automatic transmission, the three wire speed sensor for the speedometer is located on the extension housing of the transmission.
IAT wire colors
Which engine??
check the vss located on the tailshaft of the transmission for the speedometer issue the odometer is figured out based on the speedometer also so it will quit as well. this sounds like either the sensor is bad or a short in the wire from it The cord for the speedometer came undone from the transmission or the gauge cluster is bad
