I wrecked the car about two weeks after this and wasnt really in the mood to post about 1jz i couldnt drive lol.

yep thats the one, it sits right next to a brown wire.

I cut that one on mine and the oil light came on

Remember this is only for the 95+ sc 's . The wiring is slightly different for the nsw circuit .This should NOT be disconnected on 94 and older cars

I have r154, so not a auto/manual ecu issue with me.

can someone with a 95 sc with the service manual please track this wire and let us know what two places it ends at?

you have a power fc right ?
Well I've been using the 2jz map sensor, but the map was set to normal on the PFC. Well yesterday I switched it to sw20 and the rev limiter is gone.

i am using the 1jz map sensor, so i used it's setting, then i also tried the apexi 3bar sensor, which i also have, but it too had the same problem. . .

Still wish someone would track this wire on their 95 :\

Speaking of the low oil light, I remeber when I was having the cut it was always on after I started the car, after I swapped out the harness to a harness that suited my car basically 5 speed soarer harness to 5 speed sc300. The low oil light went away and so did the cut.

But it is 100% something to do with a signal reaching the ECU telling the car, it has cranked succesfully and its running. Its not your cam sensor, its not your crank sensor and its not your knock sensor.

Good luck finding the right wire.

reading this makes it sound like you have to throw out the usual diagnosis for such a problem
I did go and check the grounding on the knock sensors, as well as the resistance on the crank and cam sensors and their wiring. but that was long ago, so it is nice to know it's not them(i STILL had my doubts).
so body plug that mentions being running.
All i see at the moment is a starter signal, but that throws a ecu code...
i'm stuck working with the volume 1 book, so i'll do better when in a few days when I can look in the voume 2.

due to the way the wiring diagrams work, i'm still SOL.

Without knowing which junction number and plug it is, I'm going to be lost in these pages.

I do think it's either IJ1 or IK1, but not 100%...going to look through pics in here to try and tell which for sure

edit: from pics it appears to be IK1.
Trying to find IK1's relation to engine, etc.

nothing simple(maybe overlooked).

going to try looking at Volume 1 tomorrow to use the "starter" section.

Man........I having the same problem with my swap.

But I have a 1992 SC300 MT witha 1992 Soarer MT. Can anyone help me out.

Try checking the coilpacks maybe? If they're cracked, it may misfire. Also, check the plugs.

Is there anything special I need to do for the swap, like cut cetain wires.....things of that nature.

Its a 92 SC mt to a 92 1J mt......so should it be almost plug and play?

The only time that you should need to cut a wire for the 3k rpm problem is on the 95+ SC's. If the year is the same, especially if it is a 92, it should be plug and play.

so when i did my swap i was having the same problem.. when u say its doesn't rev pass 4k.. when u throttle it does it just stop?? because the problem with mine was.. the wastegate wasn't opening up and the ecu was stoppign the car from reving pass 4k.. if i were u .. make sure all ur vacuum lines are in the right place
