odd find on a 93 chevy 6.5 TCM ignition feed wire
 

I have come crossed something i find to be odd. on the TCM ignition input wire C16 is the pin if i recall. i know its pin 16 ether C or D. On a 93 chevy 6.5. I found at the tcm the wire spliced with 2 things. 1 what I am pretty sure is a inductor and 2nd i know is a capacitor. I have included a pic this was exactly how i found it.. Any thoughts on as to why somebody would have put these in?
