trying to find engine to chasis ground wire.

Car: 2001 Ford escort zx2- Auto Trans
Hey guys hopefully I posted this in the correct spot anyhow, I am currently in the process of upgrading my sound system more specifically adding the big 3 wires to the system ( for those unfamiliar with the terminology its larger cables from the alternator to positive on battery, negative from battery to chasis, and engine block to chasis ground) so the first 2 are pretty self explanatory to find however I am having a hell of a time locating this last wire being the engine block to chasis ground wire. If anyone has any idea where this could reside or even better have a picture that would be absolutely fantastic and I'd really appreciate it thanks yall!

its the negative cable to the body

That still doesn't tell me where it is. I am fully aware of what it is I'm trying to figure out the where.

maybe not because if you had a clue then you would be able to figure it out.

again, it is the negative cable to the battery

Ok I'm not a moron where does the engine ground connect to the frame that's all I am asking, and I think you're not understanding. I'm not asking for the ground to frame from the battery, I'm asking for the engine block to ground to frame which is not the same thing. So please stop trying to make me look like an idiot and unless you are going to actually help stop replying please.

Ok thank you so much i was unsure if the transmission ground was the same as the engine chasis typically used for the big 3 upgrade. Everything I've seen on how to do this installation is with other cars and they always have a straight ground wire to usually a bolt on the actual engine block. While this was a huge help now I'm rather confused on where I should put this third 0 gauge ground wire as everything I've seen does it another way and I'm not sure if using the transmission ground would give me the same results. I'll have to do some more research thank you so much for all the helpful information though I'm relatively mechanically inclined but every one is new to something at some point so that's why I come here

Thank you for all the help ill definitely set it up like you have it. That's actually the first time I've heard that power flows that way so definitely learned something new here. I was never of the mind set of huge amp wires my problem is running 3 separate amplifiers at once and trying not to kill the battery... but with everything in mind definitely gonna beef up on the ground points I've already added a second battery and isolator so hopefully after this no more battery issues from my audio system and I can enjoy Making myself even more deaf. I really appreciate all your help especially to someone like me who isn't the most mechanically inclined I know what I know and I'm constantly learning so thanks for not trying to make me look stupid. I'll post an update after I get everything wired up on how it all worked out. Thanks for taking the time to help me out truly appreciated

not being rude at all, you don't know as well. I do know. It is connected to the negative battery cable. Since the two of you have to be spoon-fed the information then go under the hood and run your finger from the negative cable end to the ground. Then follow that wire under the battery to the ground connection on the trans. It is all one wire. This is the connection he is asking about (insert "the more you know" meme)

you wont get far with your car with this sort of attitude toward people trying to help you. Since you needed the spoon-fed answer it has been provided before quoting your previous reply
