The tach wire is the white wire in the instrument cluster plug. The glow plug wire is in the same plug. It is a negative circuit and is dark blue in position A2 of the plug. The plug is labelled.

This truck is easy....if you have the module for the door locks, DEI 456G I think it is, and no aftermarket turbo crap to work around.

If you dont want to pull the inst. cluster for the tach and wait to start wire, you can get them under the hood, under the big fuse box. In a plug that looks like its connected to the fender. Its purple in color (the plug) pin 4 DK.Blue wait to startNEG(-) top row of pins.

The tach is pin 2 on the bottom row WHITE
