Please help recalibrating speedo
I've used the link https://www.ford-trucks.com/articles...peedorecal.php and ran into one problem. The only wire I can find that's LB/Y (light blue/yellow) is in a four wire plug right were the directions say it should be. When I try to jump it to ground without unpluging it, my horn blasts. When I jump it unpluged, I can't adjust the conversion constant with the SELECT button. What am I doing wrong? Thanks for any help you can offer.

It was the black and orange one on my truck. Scared the crap out of me when it started counting up! From 972 it went up to 1100 and then jumped to 500 and back up. I set it mine at 8.00 since the new tires are just over 35". Thank you! Saved me $200 over the Superlift thing I was looking at.
