Fiat Dino Forum (FDF)

Hi all,

I disconnected the wire's switch from the dashboard without noting the wiring order
Using the wiring diagram, I tried to remake a plan for the switch command connections (sorry it's in french )
I'm certain for the 71, 74, 92, 94 and 95.

For the 90 (Fan switch), I have a doubt with 2 wires (black/blue and red). Can you tell me where to connect these 2 wires ? on "L" pins or V "pins" ?

For the 91 (Inner lights), first do you have a 3 or 4 pins switch ?
second, where to connect these 2 wires (double black and double grey/black) ? on "L" pins or V "pins" ?
Thanks in advance,

Marco

Your problem is best solved by using the principal schemes over the two switches 90
and 91 you already have added:

By using a multimeter in Resistance mode, or - if a multimeter is not availible - by
using a battery and a suitible bulb, you can determine when the contacts in a certain
switch are in contact with each other, or not.

Illustrated in the drawings below, you should look for which contact that is A, by
testing which combinations that are in contact in the switch´s different positions -
by the multimeter indications of contact, or lightning up the bulb...
(Re the fan switch, B is the off position, and not used.)
When A is identified, the position of the fan switch will give you indication if C and
D should change places, or not. (The switch ought to go from OFF to HALF speed to
FULL speed.)
Likewise, testing the inner lightning switch different positions will give you an
indication if B and C should change places, depending on in which position the switch
should activate the different inner lightnings.
