1987 S10 blazer 2.8L


The recent snow storm here in Indiana finally gave me a legitimate reason to use my 4WD. The problem is part of my wiring harness some how got wrapped around the front drive shaft. I am able to identify most of the harness that got damaged. the oil sending units both the 3 wire and the 2 wire, as well as the trannys converter Solenoid were pretty much intacted. I have 2 wires that I can't identify. both are 18ga one is a black the other landed in the Y pipe and got fried. these are in the harness that run down the left side of the Engine. any help would be greatly appreciated

 

To the switch on the front diff??

Pics would be helpful

 

I have a pic of the harness I am going to post. IT is the small single wire on the right. I am pretty sure it is for an option mine doesnt have but i just want to be sure
