so I’m working on a 1975GMCK 25 small block 350 TH 400 and I jumped on here a little while back and asked for some help with some wiring however, with all that being said and done, it was a mess so I ordered a new wire harness and a new fuse panel 21 circuit. so I do have a few questions. I can’t figure it out because when I read the directions, it tells me one way but then it tells me another way so I’m doubting myself here so I’m gonna post a picture of my view tunnel that I’m not all the way mountain in yet, but on my view, there is no spot for battery or power so I’m not sure where I’m supposed to be hooking the battery line that goes for my battery up to my solenoid to my solenoid, my alternator alternate up to the pane. So I want the picture of it. I’ll show you that beautiful link with the two screws. There was originally on my truck that was originally in the back of the old view panel that went into my fuse panel originally. When I was reading up on this, it told me that Magean switch would bring power over to my fuse panel. However, I kept my voltage and I got nothing and nothing was even lit up when I put my wire on the batteries. But then I also look at another form as you how to do this and not when you stated to run it from that view or that maxim fuse into the back of the fuse box for the fuse box to gain power, but there’s not a spot. So I did upload some photos this time and hope you guys can help me do the best of your knowledge. I’m still routing my wires so this is just a run down if it two weeks later here I would like to go ahead and get the wire checked away after I’m done rewriting everything and making sure everything’s pulled out that I don’t need. There’s any other suggestions or ideas you guys can give me it. I’m open to whatever other than that, you guys are awesome have a good night and hope to hear from you soon

Oh boy, those painless kits can become anything but in short order. I have one myself and am not looking forward to that part of my build. However, if you do like they suggest and lay out the old on the floor and match up with the new, I see how it might be a bit easier. It's the getting the old out onto the floor without making one (or several) cuts that is the trick.

Not going to lie, but reading this as one solid paragraph makes my curmudgeonly brain hurt. I need to reread it again and see if I can sus out the question/problem in a fashion I can respond to. It seems pretty straightforward to just run wires from the fusebox in their respective directions but I know that's not reality.

One thing I can't stress enough is good quality grounds. Cab to frame, box to frame, engine to frame and of course battery to frame. Let the frame of the truck be your ground bus. Without decent grounds, you will drive yourself crazy chasing seemingly unrelated weirdness all over.

First off, do you have a schematic for your truck?

I noticed the start date, but for some reason it came up on the feed as fresh.
