Hi Folks, I have a Link G4 Supra plugin hardware version 1.0 in my Single 6 speed MKIV Supra. Recently I wanted to add 2 more digital inputs however I have already used all I can on the expansion connector. I found that in a JSPEC MKIV manual Supra DI4 is an electrical load sensor and DI5 is the start signal. These are not being used so I used DI4 for my clutch switch for the flat shift and had planned to use the DI5 as a switch to enable or disable another function. I have set both DI4 and DI5 up as GP inputs, toggle type, pullup on, on level low and active edge falling. When I ground DI4 I can see a change, when I ground DI5 there is no response. I have checked all the obvious things like wires all ok, cable is tight into the loom connector ect but I can't figure out what is wrong. Can anyone give me a pointer as to what I might have overlooked? Thanks, Johnny
