The ignition switch housing has gone bad in my 70 F100 pick up. All the parts catalogs I looked at say the same thing. 70 -72 Trucks with serial # G90,001+ used part# DOTZ-11572-A. The serial # on my truck is well within this plus side. I ordered the replacement switch housing and the electrical connectors for the wiring harness are of the wide blade type. Unfortunitly my old switch housing and harness connector have a pin or bullet style configuration. The connection patterns, plug shape and housing body are exact. Trucks 68-70 with the serial # before G90,001 used part # D1AZ-11572-C. I called the part supplier that I ordered the switch housing from and asked if the earlier year pt. # had the pin connector configuration I needed, he stated it also had the wide blade style. He also stated that if the truck was assembled in CANADA it could have several different configurations. Checking the manufacturing plate the truck was assembled in the U.S. . Can anyone confirm that pt. # D1AZ-11572-C for 68-70 has the blade connectors also? Can anybody tell me where I might find the correct housing I need ? I dont want to modify or hack into my original wiring harness. Thank You !
