I was looking to replace my analog DIC with a Digital. I have read the threads on this and other forums. I seen the hack to get a NON-97 digital DIC to work on a 97. My question is what are these parts ('Yellow' #1 and 'Blue' #2) attached to the wire loom. When I pulled it from the donor, I cut the wire high enough to include them since I did not know what they are....
