Range sensor jumper? Neural safety switch conversion?
 

Swapped a 12 valve into my 03, I used the 47rh transmission with the electronic shift ford 273 mated to it.

My problem is since I deleted the factory Ford trans the computer doesn’t see P or N coming from the trans so I can’t “turn key” start the truck or shift into 4 low. I can easily wired up a push button style start off the relay but that doesn’t solve my 4 low engagement issue.

Anyone have any input as to which wires it can jump or ground out to fool the truck into thinking it’s in neutral? Keep in mind I cut off the wire harness at the transmission so all I have are wire colors to go off and not a numbered connector.
