Ok so i got a 96 blazer a couple months ago and I want to swap the front end.
I have a 98 blazer that I am going to use the parts off of but I need help with the wiring. Does anyone have any diagrams or photos to help me figure out which wire I need for each light?

 

I assume the 96 has sealed beams right now. You need the pigtails for the 9005/9006 bulbs. Connect the grounds of the pigtails together with the ground of the sealed beam plug. Then connect the pigtail wires for high and low beam to their respective match from the truck harness. If you need pics, I can take one of my wiring.

 

I think I may have it figured out. Thanks.

 

This is why I like having, and being able to use a voltmeter. Turn on headlights, find a ground, then find the 12v. Voila, problem solved.
