Help with Calibrating PSOM
I had to get a scrap yard replacement and the new PSOM needs to be calibrated. I did the math and know how to set the calibration and what it should be etc... What I can't find is the cable labeled PSCM that needs to be grounded out. I find plenty of posts for the location of this for the F-150 but none for the E-150... any help is greatly appreciated.
Also does anyone know how I can reset my odometer as the new unit has over 100K more than my van actually has.... do I need to swap the EEPROMs? Or is there an easier way to do it?

Found the wire - It was located on the drivers side against the firewall all the way against the outer wall. The sticker fell off so be advised it may no longer say PSOM on the connecter but it's the only loose wire that should be in that area and it does have a black connecter on the end single plug.
