Charlie if I wanted to lighten the car I would reduce my personal weight

The UHF/Terraphone is so that if somebody in the pits has a UHF radio you can transmit and talk via the Terraphone (intercom). I gave up trying to get it work, the PTT works, you can hear incoming, but, you can not transmit. A job for another day.
I appreciate the comments Charlie. Plan is to test it at he Paul Stokell day at QR on 28/11. Do you still want to take it for a spin?
Well today most of the wiring is done. Low or no coolant will trigger a 100 db alarm as well as a warning light. Oil/water temp, set to trip at 120c have been wired up, however not sure if they work... Also installed 2 air temp sensors, one in the mouth of the car and another on the air filter. So all the innovate ports used once the last 4 sensors are installed (steering, brake/fuel pressure and TPS).
Tomorrow is clean/tidy up and possibly install a high brake/rain light.
