As noted in many posts this is a very simple instal
The only wires from the TT
I used are:
the black (ground),
the red (always hot)
and the green (to the ignition switch "run" wire)
I used the run wire at the main ignition switch connector.
The blue wire I did not use (it normally runs to the acc. position )
When the TT is engaged both cooling fans operate for the
duration of the timer.
A nice feature I deem as I have a
NA rad in my turbo wagon and thus no
turbo expansion tank .
Interesting, I have a n/a radiator in my legacy but it's got enough cooling capacity for my car i've never seen a need for a turbo timer. I did see a need for a new coolant temp sensor after my old one went bad and caused a lot of overheating issues.
