Installation of the unit was an absolute doddle due to the supplied harness.
All I had to do was remove the lower dash tray to allow me to get at the
underneath of the steering column. The plug under there is unclipped and the
harness inserted in-line. As there had been a previous FET turbo timer
installed in the car, the wire to the handbrake had already been installed
(and even had the correct connector on it). It was a simple matter of
plugging in the handbrake cable, connecting the earth and plugging in the
unit to the harness socket. Switching on the ignition resulted in the display
lighting and it was a simple matter to choose the number of minutes (1-5) to
run after switch off. I set it to 2 minutes as I feel this should be more
than enough, as I normally cool the car down a bit by driving sedately for a
short while before switching off, in any case.
The unit tested out perfectly, keeping the car running for the set time
after switching off, removing the key and even arming the immobiliser.
Immoblisers can sometimes make it difficult for a turbo timer to operate as
power is removed from the ignition system. Luckily in my case, the power is
maintained. I also ensured that the failsafe switch on the handbrake operated
correctly. When I released the handbrake while running on timer, the engine
was immediately cut. While it is not essential to have the handbrake
connection, it is a good precaution to take. It stops the car from jumping
into gear and driving off when there is no-one in the car.
UPDATE: I recently had an enquiry regarding the wiring of the unit (that
isn't part of the harness). I thought I'd post the info here for anyone else
that might need it...
The White with Red stripe connects to the handbrake. The Black with Red
stripe connects to ground (chassis). Red, Blue with Red stripe and Yellow
with Red stripe all go to the ignition system harness.
