Hi Dimitri, thanks for your reply. I think this stalk must have been swapped over at some stage and might be off i am guessing a later 240z, maybe a 73 model or something because at the end of the stalk bit it has a button that pushes in, i am assuming to flash the high beams maybe?
I took a look at two other early 240z that i have and they dont have that wire or the button at the end of the stalk either. So i think ive work it out!
