isolating them from the other high powered accessories, and in particular electric motors (windscreen wipers, etc.).
Do not shorten the cables; they will be adjusted later.

isolating them from the other high-power car accessories, in particular electric motors (windscreen wipers, etc.). Do
not shorten the cables; they will be adjusted later.
It is therefore not essential to wire the REM input, the DSA 500 RT being equipped with a signal detection system on
the high-level inputs.
