Poirier4

Hey guys, I swaped a 3sge beams into my s14 in october 2015, ran it until is stopped running, so I thought ecu was fired, turned out to be just a cut crank pos sensor, anyways by the time i had found why it wasn't running I had bought and cut my harness to run the aem ems-4 as I am planning on going turbo in the future, (once all my other projects are done), had it all running and stuff, but the thing is the ems-4 doesn't run dual vvti and was a waste of time and money and I wont be able to tune properly without changing the cam gears,...... but that's ok my other project will get the ems-4

Running oem harness hacked up to put ecu in passenger footwell

Now i needed a new harness which I bought and installed last night, only a few wires need to be hooked up from the stock f3 plug to the ecu box (alternator, some powers and grounds, tach signal etc)




Lexus is300 ecu box mounted in the engine bay

ready to install new engine harness

New harness installed in stock location


couple of things I need to button up

Alternator was pretty simple to wire up last time (Middle plug)
S= 12v constant (senses current at battery)
L= Lamp (should I plug to e202 (white/red I had just put switched ignition last time)
IG= Igniton switch


only wire I got out of these three connectors is the starter wire so I can start my car with the key #awwwwyeh turn key swap bruh lol

E202 Plug ? Can someone confirm?


1- yellow - alternator "S" wire
2- green reverse light (Doesn't matter which wire) 3- red vss
4- unused neutral position switch
5- white/red alternator "L" Wire
6- green/white reverse lights (Doesnt Matter which wire)
7- red/yellow vss
8- black unused neutral position switch/5th position switch

anyways.... I'm trying to figure this out as it's a JDM Model Zenki converted Kouki with a beams swap, lol trying to get everything working and have a very simple oem style harness,

I had tried plugging the 202 plug for the alternator and vss reverse lights like time when i got the car to run with the aem but it didn't work, reverse lights didn't work, vss read nothing and alternator wasn't charging lol, anyways any input on that would help.

OH! and if somebody has made their own f3 to wiper amp and wiper plug harness that'd be great!!! as right now I have wipers on 1speed on a switch
