Naked Buell Posted November 30, 2017 Share Posted November 30, 2017 Okay guys connecting the ecu one wire at a time and have some questions. On Plug F47-22, it is main fan control. Where do I connect this one? On Plug B58-9, which is the park switch, do I just ground it? On Plug B56-9, A.C. switch. Air conditioning switch. My Brat doesn't have air. What to do? On Plug B56-16, tach. Can I just hit the stock ea wire that was on the coil? Thanks for the help. Link to comment Share on other sites More sharing options...
Gloyale Posted November 30, 2017 Share Posted November 30, 2017 Ground trigger for a relay setup to run fan Leave park switch unhooked Leave A/C cutoff unhooked Tach wire to EA yellow tach wire, either at coil or in car near dash. Link to comment Share on other sites More sharing options...

Naked Buell Posted December 1, 2017 Author Share Posted December 1, 2017 Ok, park switch taken care of. B56-9 is AC switch not cut off relay. That is F47-22. Just leave both unhooked? Link to comment Share on other sites More sharing options...
