Hi Dave, Further info off ESI F34 Ign feed to coil, switched by ECU pins 57 & 71 F24 Ign feed to brake switch monitored by ECU pin 51 F15 Bat feed to brake switch monitored on ECU pin 23 F36 Ign feed to ECU pin 27 F31 Bat feed to ECU pin 15 F30 Ign feed to CFSV & EGR Earths on ECU pins 2 & 28 K line from pin 7 DLC goes through Immo pins 8 & 7 to ECU pin 29. Try connecting K Line of diagnostic tool to dirct to pin 29 of ECU and see if comms can be achieved then. You may need to cut wire near ecu so immo doesnt pull k line down. Mike ps give me a ring this morning I may be able to fax you diagram from ESI.
