So I started not having the starter crank intermittently, until I shook the battery cables near the lead terminal on my stock ,original? 2001 cables. Right now I just have the primary battery to starter cable and the battery to the pcm cable . I ended up getting the #2 ga but after getting them I see I could have been more than happy with the #4 ga. I made it 25 years with the original twistie tie wire. The setup is very well made but its a little awkward at the battery end the way it hooks up to the cable connector. will get more pictures tomorrow just in case its something misaligned with my install but very nice
