First off my blazer is a 73, it has wiring problems. Some wires the insulation is falling off and some have actually failed inside their insulation. I have determined that I cannot fix the many problems that I have. Heres my questions. 1. What is the first year of blazer to come with blade style fuses? 2. I have an 89 that has the wiring harness in it, will it be too different to use or too much of a pain to cut off all the extra? 3. I have a tight budget on this thing, is there a quality wiring harness that can be had for cheap? 4. Can I go to a wrecking yard and get a harness from a truck or do I need one from a blazer? The only caveat to this is it has to have blade style fuses. Please keep in mind that I am by no means a electrical person, but have been able to accomplish everything else I need to do on my truck. I am looking for an easy way out, but I don't want the thing to have any problems so if the right way out isn't the easiest I will do the right way.
