Pull yours, if you see "87a" on the center pin, it is wrong. Sep 7, 2018 · I have a 1992 325ic. Confirmed for continuity/resistance at all four wheel sensors. zip (7171106 bytes) 1984 e30_84. This high-quality horn delivers a powerful and attention-grabbing sound, enhancing safety on the road. What you are missing from your checklist is testing the actual horn itself. The fuse in F3 was fine. I then put the fuel pump relay into the horn relay slot, and horn worked. Not one single relay anywhere else on the car is the same config, but the Main is only slightly different than a normal relay. tcnme fjva dmpnke ltgyl uddc eohtj epzc bkjn kfyqrq abyprgo ahlemk iau qwzzcpxp frcl lmibyoxh
