In the first picture, right next to the blue ign lead on the table (on the front of the table above the drawer), theres a green plug right next to the engine mount. Thats the fuel temp sensor there on the secondary fuel rail.
The second pic shows (sort of) where the secondary injector rail is in relation to the primary rail. (the red plug is on the primary rail)

If your running a PFC then you dont need it.

Isn\'t the heat light being on normally caused by a problem with the heat sensor on the cat, or lack of.

Hi Mate,

It\'s decatted.

When you fit a PFC the light is used as a warning light for any potential issues i.e knock, detonation etc. I done a check and the cmmander has highlighted the fuel temp sensor.

The heat light is used as a knock warning light. Mines not connected (1680cc secondary kit) and dont have any issues.

If you\'ve cut the wiring (or there\'s a short in it) for this sensor you\'ll get an error light. If you leave the sensor connected but not actually in the fuel rail, no error. I\'ve not actually run it without the sensor plugged in so couldn\'t say whether that gives an error but as it\'s the same as cutting the wires then I\'d guess it would.
