Put one on the 86, nice kit, good instructions, excellent quality. Highly recommend the 4 ga. power wire option,more of a necessary thing with a 130 amp upgrade.
Service was good - I screwed up the diode they give you attached to a wire. I e-mailed them and they told me what part from Radio Shack would replace it or said I could order one from them. I ordered another from them but went to RS the next day and got the replacement diode, had it going in no time.
