Hello! I am currently trying to install an
ATEMU from all4swap into my 1998 SC300 with an R154 swap and I am having some difficulties creating a wiring diagram. Has anyone here successfully installed it into their SC? The main info I can find is early model IS300s, but it’s wiring harness looks to be slightly different then the SC. I have completed about 90% of my wiring diagram, but I am having trouble as to what pins I should used for the PRND32L as there looks to be a discrepancy between the documents. Attached below are the documents I have found.
Higashi300,
Did you ever figure out the wiring for the ATEMU on your 98 SC300? I have one pin left to figure out and that's for "P". What ECM pin did you connect the "P" from the ATEMU to?
Thanks sir.
I created a wiring diagram with all the correct pins. I was able to find out everything through sourcing some dealership manuals. It works perfectly in my car now. No CEL!

You freaken genius!!!! Thank you!
May I further ask:
1. What did you do for the VSS output from the transmission? I bought the Driftmotion speedo gear and VSS adapter that has a three wire connector. The connector to the A340E speed sensor is a 2-wire.
2. Do you have cruise control functionality and if so, what did you do to get that working?
