hello everyone new here, but i need advice.
Im doing an engine conversion on a car and using an engine from a gs300 2jzge however it has a built in immobiliser in the ecu,
luckily when i got the conversion kit i got the key amplifier, key and ring pickup all matching the ecu.
problem i have is i cant figure out how to wire in the key amplifier. as far as i understand there is 5 wires
(im going off these colours by memory here so i might be out)
red - positive
white / blue stripe
white
white/black stripe
the issue i have im struggling to figure out which wire is CODE, RXCK and TXCT.
if someone can sent me a picture of their F84 ecu plug and the plug that connects the key amp to the loom it'll help greatly!
i found this online however the wiring that comes out of the amplifier do not match this
not my picture but this is the same amp, notice the 3 wires are white and dont match the diagram
I have 2 different EWD both confirms to be correct. The white wires have stripes on them, what color are those?
Also what's the part number on this amplifier?
So I found this picture on Google, lucky it shows the plug it's connected to However none of the wires match any diagrams 🤔🤔
Can anyone confirm the wires on the picture are correct? 🤔
Okay after some more research the wiring diagrams ive found are for 2001+ however there is a difference as from 97-01
(my engine is a 1998 so all the wiring diagrams im looking at are for the newer engines)
dont suppose anyone has a diagram for the earlier models?

The ecu pinout/ wiring list that I have shows that the pins for the immobilizer are on the E7 (f84) plug, pins 21,22, and 23. The wires at the ECU plug should be: Pink- TXCT, Violet- RXCK, and Green- CODE, but I haven't dug into my own to confirm the colors. I would think that the wires are the same color where it connects to the key amp. Here is a borrowed picture of which plugs are which @ the ecu- https://www.clublexus.com/forums/att...-pin-out-2.jpg
You may notice that the link I posted above refers to the plug you are talking about as E7, not F84 (I believe F84 is what it's called on the Aristo). Either way, this is the same plug. It's the gray one that is somewhat seperated from the other 5 on the pre-01 ecu.

Reason: correcting wire color
