Change cooling fan temperature switch points

[Chuck W.]

I think a better way would be to have a manual switch to activate the fan.

Take a look at post number two by Qmulus in the below thread. I have considering doing this numerous times..... if I could only identify where to "In a convenient place cut the yellow/gray wire from DME to the high speed fan relays".

I would do this under the dash where the relays are located. Just find the trigger wire going to the relay and then back up and find a good place in the wire harness to splice in.

Nice mod......really want this for dealing with being stuck in traffic .....I imagine having having the fans running while moving at speed would improve cooling air flow as well.

Anybody have a idea which stock switch might give a SPST configuration? Maybe wiring diagrams show this. It would be nice to package this switch in the batwing andlook stock.....maybe a repurposed seat heater switch

If you are looking for more "fan power" why not jumper the low speed relay wires with the high speed relay? in that case, the fans will always kick in on high.

Has anyone considered the OBDII connector and sending the right signal to the computer.

The Durametric units can turn the fans on and off and set the fan speed. Perhaps this is another OBDII Arduino Hack candidate.

So doing this would negate the need for installing manual switches as triggering the Ac on will now put the fans on high right of the bat? I can't picture the jumper arrangement as yet or downsides......it's late though!
