Question about 2004 Chevrolet Malibu
The transmission range (TR) switch is part of the park/neutral position (PNP) and back-up lamp switch assembly (1), which is externally mounted on the transmission manual shaft. The TR switch contains four internal switches that indicate the transmission gear range selector lever position. The PCM supplies ignition voltage to each switch circuit. By grounding one or more of the switch circuits, the PCM detects the selected gear range by the state change of the switch input. Refer to Transmission Range Switch Logic . Switch input to the PCM is represented on the scan tool as HI and LOW. HI indicates an ignition voltage signal. LOW indicates a zero voltage signal. The four parameters represent transmission range switch signal A,B,C and Parity.
Look on transmission where the shifter cable hooks up !

Generally on GMs, if it's a column shift, it's down low on the steering column under the dash, and if it is a floor shift, it is at the base of the shifter, under the shifter housing. Look for purple wires or a purple wire and a yellow wire. I don't know what year your truck is. Hope this helps!

SOURCE: neutral safety switch
It is located on the side of the transmission, follow the shift cable down to it you will recognize it because it has a electrical wire comming off it and either a shift lever or shift cable going to it.
