hi, I want to use fan control option in ectune pro... but couldn't find a good wiring info with using a relay... does anybody have a picture for this wiring diagram... last year I have found a good info in honda-tech forums but couldn't find it in the forum right now... thanks a lot...

From memory... ECU fanc output is active ground. So one relay coil wire goes to 12v, the other to ECU output. /Allan

yes that's what I am thinking... but want to now all of the options for that maybe some other wiring for this could be possible...

There really is only one \"option\". It will only work in one way, you canÂ´t pick and choose which way the output works

yes I know there is one output option from the ecu but different relay wiring or smoething else... I don't know right now...You guys are more experienced than me...

If you can be more specific as to what options you'd like, would be helpful. Do you have an idea of what you'd like it to do?

ground to thermostat housing/fan switch. fanswitch has 2 cables ground and signal to relay in fusebox. jump from ecu fan out to signal cable on thermoswitch.

Hi calvin thank you for your response... Than I don't need to use another relay for this.

correct. EDM/JDM car?

Hint: There's already a relay in the fuse box for the fan

Ha ha ,I been running a ground to the fan relay but calvin is right, just tap the thirmistor wire and ground with ecu.

EDM.

that car is not wire for fan switch. also the ecu(edm) doesn't have fan control output. if i remember correctly

a week ago i made this fan control to one civic. it is so easy that you wouldn't believe it. no wiring needed. just go to parameters-hardware settings-adiator fan settings and make it ENABLE, fan control output FANC /radiator fan relay A12)and put the temperature you wannt have fan ON. and that is all. no wiring needed and it is working great! PS: made on EURO P30 ECU (EDM)

Yes it is just like that but in some model of honda civic you can not do it. You have to wire it.
