EJK controllers come with O2 Bypasses OX-005 and OX-009. Your stock O2 connection needs to be disconnected and the correct bypass installed if O2 present. Some CBR 1000 RR bikes
require the male connector and some require the female connector. You will only use one bypass during the installation.
Main connectors for EJK controller go to the lower / primary injectors. A single connection will install to the upper / secondary injectors
