HI, I AM WORKING ON A 85 Z28, WE BUILT A 383 FOR IT AND SWITCHED FROM A T-5 TO A TH350. WHEN INSTALLING THE NEW B&M SHIFTER SWITCHING THE NEUTRAL SAFTEY OVER WAS NO PROBLEM, BUT I CAN'T FOR THE LIFE OF ME FIND THE WIRING FOR THE BACK UP LIGHTS. IF I REMEMBER RIGHT THE SWITCH WAS IN THE TRANSMISSION FOR THE T-5, AND MY NEW SHIFTER HAS A MICRO SWITCH ON THE SHIFTER. CAN SOMEONE TELL ME ROUGHLY WHERE THE PIGTAIL COMES OUT FOR THE BACKUP LIGHTS ?

 

This is the factory wiring, showing the bulkhead connector pins for the backup lamps:

 

THANKS. SO MUCH FOR THE HELP.
