Trying to finish up LQ4 swap in a 99 fbody, and found this braided 18" ground strap sitting on the floor midway between the old LQ4 stuff and the required LS build items. Does anyone know where this strap goes, if anywhere?

I googled and searched this site and really only could find the one ground strap that looks like this at the front near the ABS that goes from fender well into the harness, common with fan ground. That one I have, and is accounted for, so this isn't that.

It could be an unnecessary part from the LQ4, or it could be something that a label came off of and I need it for the swapped block. Really bummed because I was SO careful to label everything. I am thinking (hoping) this was LQ4 extra part.

Am afraid to lift the engine back up in until I figure this out because I am doing this all alone and I really don't want to have to pull engine back down because this needs installed.

ANY help anyone has would be appreciated.

straps like that are usually block to chassis grounding...

Ok, if nobody else replies I'll just find spots, but I'd like to keep it original location if possible, anyone know specifically? I already have the braided looking strap behind the alternator going into the harness, the braided looking strap going from the Front Driver inner Fender (shared with fan ground) going to harness, so those two are in place. I am unable to find any other reference of a braid-looking strap on the Fbody that would have required removal when dropping engine, if any..

That strap is likely from the LQ4, if you have the LS1 braided ground secured then you are good to go and don't need that one. You could always use it as an additional engine to chassis ground on the passenger side of the engine if you wanted.

Find some place that looks like it deserves it, and use it.

Dude, it’s just a wire that connects the block to the chassis. It doesn’t matter where it came from or where you put it as long as it’s connected to the block on one end and the chassis on the other. Please stop trying to make this very simple thing into something complicated.

This is a fbody that I don't want hokey rigged up stuff, if it's a factory ground that goes to a specific place, I want it there for me or mechanics in the future, or just to be "right" to match troubleshooting guides and documentation. If you don't have anything constructive to contribute maybe you just shouldn't.

While you are correct in that things should be "right", when one sees a braided cable like this they will know it's a ground, and not worry too much where it has to go. As long as it's between a possible source of a charge and the chassis where it can ground out. Not really too much to worry about here.

I like this mentality. Details go a long way. One thing to note, wherever it ends up, clean up the contacts to ensure quality continuity. Don't ground to a painted or oily surface. I'm sure you know this. Good luck!

Thank you, appreciate the advice.

To the others: would you want your mechanic working the way you describe? The car should be right. If the ground came off a certain spot, it should go back on a certain spot. I'm sorry but I reject the premise that this is unimportant.

Anyway, I have a contact for a guy who parts out FBodies for a living, need to go see him for the little rubber shock tower caps and a brake line harness clip and other doodads, if he identifies it as an FBody part I will make sure to update this post for others. Then the heart goes back up into the beast this weekend I hope!!!

Considering you're swapping in a lq4 a case could be made that your car is already wrong. That said the closer it is to stock, especially on the wiring, the better it is for anyone working on it. Trying to figure out things done by previous owners is the biggest issue with working on older cars. If you find that the ground is supposed to be in a certain spot definitely put it there just to save everyone a headache later.

Noted and accounted for. Thank you all.

IF LS1TECH says it, it must be so. No better resource anywhere for LSX stuff.

Thinking your strap is the alternator to chassis but haven't found a pic yet. I'm still looking lol
