A quick question for the mapping peeps, to confirm the below..
According to the wiring diagrams, I have access to, the ‘Rad Fan Low’ (Pin21) wire in the EVO5/6 cars produces a 12v negative output when activated.
The trigger then completes a relay circuit with a positive value from the ignition switch, to relay/switch on the fan.
Reason for asking:
I have an E2 based car, with a remapped 5/6 ECU, but the ignition feed mentioned above was previously cut by a sparky, not long afterwards as it was blowing fuses.
I’ve been running a secondary fan switch, until now as its only really come round to the high priorities list compared to other projects.
