Naked Buell Posted December 4 Share Posted December 4 So when you do a Ej to Ea swap, on the ECU, there is a wire for the radiator fan, I am thinking, the ECU controls the fan. But, on the Ea cars, you have a sensor on the radiator that controls the fan. My question is, Do I have to run the wire from the ECU to the radiator fan or can I just leave it the stock way on the EA cars? Thx guys. I appreciate your help. There is a lot of info on this site with you guys. Link to comment Share on other sites More sharing options...
Numbchux Posted December 9 Share Posted December 9 Do not run the fan directly to the ECU. There are 2 outputs from the ECU for fans, and they are both to trigger the low side of a relay. The temp switch in the radiator works fine. I've done it that way. I think the only time it would be an issue would be if you have A/C, as you would need airflow even if the radiator wasn't hot. PS, I'm sorry I haven't responded to your email. I can get on the forums at work, but I can only get to gmail on my phone right now. And I'm SUPER rusty on EA82 stuff. I hope you're finding the answers to your questions. Link to comment Share on other sites More sharing options...
Naked Buell Posted Tuesday at 08:32 PM Author Share Posted Tuesday at 08:32 PM Hey thx Matt for responding. I'm doing my best trying to understand what is needed. When you read through some of the info on the write up, there is things that are assumed to be known and some of us aren't 100% sure of things like some of you subaru nuts. That is what I need help with. Now see, I would have just wired it right to the rad. fan. Thx for the info. Link to comment Share on other sites More sharing options...
