Speedo Cable Broken At Rear Of Transfer Case

[p67]

My speedo cable got broken in the forestry [presumably]. Wires got pulled/ripped out of the socket that plugs into the back of the gear box where it meets the drive shaft.

Ute is Hilux 4x4 2002.

I have 3 wires.

I am assuming one is +5-12v, one is ground and one is a pulse signal from a tacho I would imagine they would use a tacho of some sort]. Colors are red, pink $ green/yellow.

Is there anywhere I can find a wiring diagram of that loom? I should be able to solder them into the plug again.

Bit of a laugh. I pulled the gauge cluster out to see if the back of the speedo might have some clues. There is a printed circuit board on the back with about 3 flat multi plugs attached to it.

I was like "What the hell??!!".

Although I did manage to meter [ohms] the 3 wires to 2 of the multi plugs, I have think they are +, - and signal. Its the end at the tacho Im not sure about now?
