How do you get to the speedometer cable of a 1990 Toyota 4x4 pickup truck?

There are two types of speed sensors and you can't tell until you look. One is electrical/magnetic (VSS) and one is a cable that goes directly into the instrument cluster. Here is my answer to How to replace the Speedometer Cable in a 1990 Toyota 4x4 Pickup 3.0 3VZE V6. To remove the cable you will need to unhook the e-brake assembly and seperate the speedometer cable from the e-brake at the firewall by the gas pedal. On end goes to rear of the instrument cluster and the other end attaches to a small gear at the rear of the transmission. The instrument cluster will need to be removed.
