Some feedback:
In my case the connector behind the sterering wheel was in very condition.
The originally installed brown wire was replaced but unforunately the results were not the expected.
The wipers' speed was somehow increased but not as it should be.
Still the water temp and fuel gauges readings increase as more circuits switch on...
There should be some voltage leakage. (somewhere
)
Concerning the ignition switch discussion it seems to be really a
good or
no good situation.
It either works and turns the engine or it simply doesn't.
I do not know whether the voltage drop can be caused by the switch itself.
