Sorry I didn't give enough detail; these 2 devices are on the interior firewall, so under the dash...(I pulled out the dash for a re-leather, I'll send pictures later). So these 2 devices are behind the wiper speed control.
The black box to the right is definitely the FIAMM horn relay; the left most (brown) wire comes from the Country/City horn switch, the big honking
white wire goes to the Fiamm compressor. For the cooling fans...I guess my question is; do the fans ever come on automatically? Looking at the schematic;
1. The (2) cooling fans are hard-wired in parallel.
2. They won't run unless the Fan switch is on...the output of the fuse block goes to the fan switch, the outputs of the fan switch are to the Radiator Fan Light in the speedometer and also to the 2 fans themselves. So any relay is upstream of the fuse block.
So the question; the radiator has a thermal switch at its base, does it drive the relay ? If so, that would make the toggle switch on the dash an over-ride only...
Thanks again, guys...Lee
