RA Rodeo

I should have added.

Stick your head under your ute. If there is no cable coming from the gearbox then it is electronic.

There are 3 switches on the TFS Rodeo.

One for reversing lights (2 wires)
One for 4x4 light (2 wires)
One for speedo (3 wires)

This is on my 97 model so probably different wiring locations to yours.

I followed the wiring up from the gearbox and into the engine bay on top of the drivers side inner guard where it then went through the firewall and into the cabin under the dash. As I wanted to change the signal before the computer I tried to get at it just after it entered the cabin but it was too hard to get at. So I cut the wire on top of the inner guard and then soldered two wire extensions (one onto each cut end) and back into the cabin. I then wired the speedo correction unit and zip tied it under the dash somewhere.

Works very well and is heaps cheaper than the 4x4 shop units.

Thats interesting. I wondered why my Frontera registered correct speed when I fitted larger radius tyres.

When I went from 205/75 16 to 225/75 16 my speedo was then spot on. However with the 31x10.5 the speedo was out by 6%.
