Thermo fan mod au to bf

[car10002]

Hi everyone

Was just wondering you know how years back in the ef/el possibly au most of you did the thermo fan relay mod as in add another relay and connected to aircon pump so the fans cycle all time as the clutch cuts in and out, would that relay mod also work on the ba to fg

Below diagram pin out may help you work out answer

Pin 30 to high speed wire on factory relay block
Pin 87 to ground
Pin 86 to aircon pump
Pin 85 to ground

also in a ba is it ok to hot wire the fan relays on low speed all time as in ground the blue wire for low speed with it being left connected to the ecu pin the way it was and leave rest as is and leave low speed connected to ecu and do same with the relay mod for the ac or will it damage it

usually the ecu earths the relays when it senses temp and turns on fans

Could that diagram be applied to the au to bf as the thermo fan wiring diagram between those models seem to be same and will just splicing into the relay earth while leaving connected to ecu damage it when grounding that earth wire

That used to be a popular mod years back

Attached is the el thermo fan wiring diagram with that mod click on link to see

Thanks
