Alright, the question has came up SO many times, so here's the final answer

I don't think I could make this any more simple







#1
This wire comes right off the - terminal of the battery, and follows the + wire leading to the starter. It splits out of that harness right by the upper control arm and runs over to the engine block. On AC equipped models (as shown) this wire bolts to the AC compressor mounting bracket via one of the bolts that bolt it to the block. Without AC, I can only assume that the wire bolts directly to the block itself.









#2
This wire is bundled in the wiring harness for the alternator. It splits off from the harness and runs up to a bolt at the rear of the power steering pump that mounts the pump to its bracket.







#3
This ground goes DRECTLY from the cylinder head (bolts to the head using the same bolt as the engine hoist hook does), and runs right to the firewall.









#4
This is probably the most commonly overlooked and asked about ground on the 22re. It sprouts off of the same wiring harness that runs between the upper and lower intake and has all the fuel injectors and VCV pigtails as well. It is actually 2 wires, that both bolt together at a bolt that secures the upper and lower intake together.









Hope that will help some folks out

Just wanted to say THANKS AGAIN, I read your post, went outside and hooked everything up... starter fired up first time and everything electrical works

Sorry, sorry, I forgot about the first pic Trav!

You should have shown your brake booster in the other pics though, would have made that bastard look oh so shiny and clean!!

It stands out a little too much in the pristine engine bay.

So whats the point of #3?. Its cut on mine and I didnt know it was a main engine ground. I was just kind of like hm, a random grounded wire

toyota4x4907

Oh and without A/C, #1 does bolt directly to the block

iamsuperbleeder

Well in a nut shell, #3 grounds right to the head, and that makes it a direct ground for the electrodes on the spark plugs. Without it, you may not be getting as strong of a spark as you could be getting with it


well good, I'm glad my assumption was right, lol

thanks!

toyota4x4907

I see. I'll check that out tomorrow. Thanks for the thread Bleeder

kiyobrown

Can't deny that! But now when I see a pic of your rig, all that pops into my head now is "BOOM!"

If #3 was not grounded, would it contribute to/cause pinging?
