I have a 1984 Full Size Suburban. I have recently replaced the steering column and the new one (from the junk yard) came with an in line connector that has 5 male pins on one side, 7 female pins on the other side, and a heatsink in the middle. The whole connector is about 6" long. this connector was not on my old setup but the necessary connectors are there to connect it. It is stamped with the name Lectron on it with some wiped off numbers. Does anyone know what this is for and if it's necessary?

 

I just took a picture of one of my spare steering columns and the only thing I see is the ignition switch (circled)
This is a column for a mid 80s full sized blazer

This is not the ignition switch, it goes in line with one of the wiring harness connectors from the column here are some bad pics, sorry i couldn't do better.

Sorry I have no idea what that is for. It certainly looks like a heat sink, but I don't know for what.
