While still fighting with the now famous white screen (I'm the captain in Moby Dick) I have identified and checked all my engine's harnesses. I found a connector without apparent use tied to firewall harness at wiper motor position more or less. I suspect it is for TI harness for LT1 engines, is this correct? I suppose that, like with the TCS RH temp switch there is an TI extension harness which uses it. Thanks, Roberto NCRS #30019, RMC
