anti theft control part number question
 

my 87 944 had # 911.637.104.02 anti theft control module will this also work in my 1986 turbo 944? can someone cross reference the part number for different applications?

Same part # as the ones in my Both my 86 turbos. My 88 and 89 turbo-s Have a 928 part #. Early cars had that key switch in the rear quarter. The later cars work from the door lock and also have the lights on top of the door lock knobs, maybe that is why they are diff.
