Hey ive been looking around for a while now and i cant seem to find what im looking for.

I need a Wiring diagragm on wiring the Greddy Emanage Ultimate up to my 99 SC300. im about to go Na-T. I know there is a universal harness for that. but while ive been looking around ive seen some info on a plug and play for the IS300. and i thought that the automatic is300 for some years the ecu were the same as the SC300 vvt-i. so would that work and if so where are they able to be purchased? ive seen links for them to my.IS store but the links are broken. any info would be greatly appreciated.

I have no problem wiring up the universal if i have a diagragm. But would also like to have some info on the plug and play.

Also back on the is300 auto and sc300 vvt-i auto ecu being the same. does any one know if the is300 5spd would work in the sc300 vvti. the purpose would be to avoid a check engine light when going five speed. because of the auto ecu not reading the auto trans. dont wanna have to check codes randomly beacause my light is always on. or removed.

I have a 99 SC300 engine (supposedly), and the ECU looks like the IS300 one.

I will be using the emanage ultimate as well, so I'll be happy to find/provide any information you need.

But if you want a PNP harness, you should be able to get one from boomslang.

i found a pinout for the car from soultrains thread: https://www.clublexus.com/forums/sc-...9-sc300-6.html

another question i just thought about. my greddy emanage ultimate came with a harness that i thought was for another car. but after thinking about it. the only harnesses they have are the plug and play and the universal. the plug and play should have connectors on all ends right. and the universal should have loose ends. the one that came with mine have loose ends but the person i got it from thought that it was car specific. was he wrong?

You'd have to post a picture of the harness, for us to answer that.

Good choice going EMU because it has extra features such as temp control, self tune, 2 step. Theres a lot of information on my.is forums. The "01" IS uses the same ecu pinouts as the 98-00 SC plugs are just labeled different.

more like a few hours but here it is.

and the connectors have actually been cut from the rest and the other end looks to be cut also. but this may have been just from dissassembly. but i dont know. it seems if it were connectors they would have just dissconnected them instead of cutting and leaving open wires from there car.

Your harness is cut in half man. Its a universal. I have a universal 1.2 meter if you want it. I bought the plug and play for the 1JZ so I don't need it anymore. Its damn near completely labeled too.
Here is what a plug and play looks like.
