I know, you'll have to add a wire. Forgot to mention that.

Cool. Saw where you were going with it. So... Should I do this to my high side too as well as isolating each bank? Basically asking if I could isolate low and high signal for each bank and reference them to the right locations on the 411

You shouldn't have to mess with the high side at all, unless your issue is different from what I had. I would just do one thing at a time.

Ok. Bout to do it.

Fixed it!!! Before adding the wire it would only work on first start of day. Now it's working all the time... Thank you for all the help. Got more stuff to ask but I'm going to relish this for a bit. Thx Christian!!

How do you lose a big block? Have you tried looking under the hood?

Awesome man! Happy to help! Now that confirms mine wasn't some sort of fluke.

Are you still getting the P0300? Or is that fixed too? I made a thread some time ago on my troubles after I did the 0411 swap. That's when my code popped up.

Here it is.

This is the first I've heard of this bridge wire, is it a 98-00 thing? Mine's a 97.

I'm thinking so, might also be big block specific but no guarantee there, I'm just guessing that since there are quite a few 5.7s in the 98-00 range that are 0411 swapped, and I haven't heard of this issue from any of them. I did quite a bit of searching around and really haven't heard of this problem at all, which is why I had always assumed it to be an oddball issue with my truck in particular.
