DASH pt.II
finally i've found the correct coolant temp sender for the dash.
many thanks to new1ru who's supporting me with tons of infos too... thanks mate!
just needed this, to do all this...
made an experiment. bought potentiometer of each size from 470ohm to 100kohm.
put these, one by one, in parallel with the grey temp switch, (which actually is a ntc sensor) with one pole grounded. with a relay and a lamp, i simulate the fan switch points.
the green lamp simulates the fan working.
now i have all the elements to make the fan switch points adjustable from inside the car.
wanted to put the fuel pump under switch too...
this relay box had been made out of a oil-bottle (for temporary use?).
here while clearing a bit the wiring and fuel hoses, in this engine bay corner.
(cut and soldered at proper length many wires too).
my back is crying, these weeks tests revealed both lumbar and cervical hernias. (atta rubbish, gotta work on these ones too...
)
needed to lift up the car just for a wiring job...
working on the dash, made some brackets and put some leds and lamps...
never wired leds. deflowered myself about this one too...

central switch panel assembly and connection terminal...
...so:
dash before...
...and after.
dash:
-std speedometer on again (now working! never seen on this car);
-fiat punto mkI rev counter (wich correctly communicates with the edis4 module, while the std ford doesn't);
-yellow (around 5krpm) and red (ar_d 5.8krpm) leds (still unconnected to mj ecu);
-blue hi-brightness led (looks white) => fan on (either manual or automatic);
-auxiliary oil red lamp (with redundant cable from the pressure switch);
-orange switch lamp (to be set around 6.5krpm) (still unconnected to mj ecu).
central switch panel: (from left to right)
-fan switch;
-blue lamp => manual fan switch on;
-10kohm potentiometer fan temp switch point adjuster;
-black switch and green lamp (for further use);
-fuel pump switch;
-yellow led => fuel pump off;
-green led => fuel pump on.
(only thing doesn't work is the fuel tank gauge, still driving with a 10lt canister in the trunk)
fan wiring diagram (with in car switch point temp adjuster):
fuel pump wiring diagram:
money spent so far (from post#136): around 15eur / 18gbp.
just for leds, resistances and potentiometers.
the rest, switches, relays and lamps were from dumpsters or i've already got 'em...
that's all for now...
thanks for reading.
