bad starter relay?

OK is this stick or automatic? If it's auto, hook everything up "normal" and hold the key to start while you wiggle the shifter through P-R-N and see if it tries to start or clicks. If so, likely the shift linkage is out of adjustment. If not likely bad brown wire or bad neutral switch

If it's a stick then look for trouble in the wire and to the clutch safety switch. Either stick or auto, that wire is grounded by the switch
