Please help with two wires?!?!

[MattNoyes]

Hello all,

I recently re-did my entire power steering system on my 92 FJ80 and in the process pulled the battery and battery trey. There is a black wire that connected to something coming from the ignition coil, and then there is another wire I'm not sure where it went but its bundled with the green ground wire that runs up to the positive side of the battery terminal. I will post some pictures. I've spent all morning scratching my head and this is the first time I'm posting a thread here for help as I can usually find my answers throughout all of your wonderful threads. I'm kicking myself in the pants for being a stupid dummy head and not taking note of where these two little buggers connected! Thanks in advance to anyone who pops their hood to take a look for me. These two wires are the only thing that stands in my way to finish up.

Not OEM or was repaired with ring terminal. No clue. But bumping the thread for ya.

I think the black wire from ignition coil is a ground.

Yeah IDK, its coming out of that same black plastic tubing as the green ground wire that runs up the positive battery terminal. It's brown or orange I can't really tell because its badly faded. Thanks for your reply and help!

Yo0u're probably right, I sure hope someone takes a quick peek at theres and can tell just where it connects. Thanks for the reply. Appreciate it.

If I am thinking this correctly, there are four grounds, body wheel well, ignition coil, air intake chamber, engine hanger near distributor cap.

Those brown wires with aftermarket ring terminals are not original. Just remove them. If your KC Hi-Liters go out, you'll know why. I have a grocery sack full of wires and terminals that I removed from my truck, and none of it was OEM.

If you're not sure, follow them. I found a K40 radar detector, front and rear, an alarm system, and all sorts of other random junk.

I'm still shaking my head after

You know you Land Cruiser guys are all right in my book I sure do appreciate the input. I'm gonna fire her up tomorrow and most likely ground the black wire which I believe to be a ground or secondary ground from the ignition coil module and whatnot and then hit them with the tester to se if they're live....its something else to put 30+ hours worth of labor in only to get stumped by a couple rink a dink wires...will post update...

All right well that black wire is the end of the harness coming from the coil/igniter, I know that much and would be happy to volt/ohm meter test the crap out of everything under the sun (Ive read the many wonderful write ups and thanks for all of those) to find out why my rig wont start but I first need to know where that ring terminal which is OEM connects to. The coil/igniter looks already grounded to me, so is it possible this was connected to my batteries positive terminal or could it really be a secondary ground, and if so where was it grounded to? It doesn't seem to reach any natural grounding points but it does reach the batteries positive terminal. If you extend the wiring harness/connecter coming off the coil/igniter you have the black wire pictured above.....please forgive my electrical ignorance, I'm gifted with fixing many a things Toyota, electrical is not my strong point. I'm hoping I can bump my own thread. I can't very well volt/ohm test the igniter/coil if the dang wires aren't all connected so please someone clue me in again I'd greatly appreciate it. I'll finally be able to sleep at night once I know where that damn wire goes and if its a bad coil/module I'll be happy to replace it.

Did you ever figure this out?

I thought one wire was grounded and the other went to the positive side of the battery but when I hooked it up that way I got lots of sparks. Mine has been disconnected and laying in the engine bay for years.

Most pics of the coil does not show these 2 wires coming off the bottom of the coil so idk if it's year specific but I have a 97 motor in my 94... I believe I kept the 94 coil as I did not swap the engine harness.
Does anyone know where the second coil igniter wire goes?
I also have an additional ground if anyone knows where that goes also.
