2002 es300 remote start accessory wire

Hey guys. I’m looking for a little help. I have been working off and on a remote start on a 2002 Lexus es300. I can’t find the accessory wire. DirectTechs and other sites state it is a “blue wire, front of fuse box”. It’s not on the ignition harness. Has anyone worked on this car and found the wire?

I have not done one but here is what AudioVox and another site list for the 2002 Lexus ES300:

Bulldog Security says ACC1 is Blue (+) at the Ignition switch harness.

Have you checked all the wires coming out of the Ignition switch with a DMM?  Toyota/Lexus does inter-mix thick and thin gauge wires.

Soldering is fun!

It HAS to be on the ignition loom, that's the ACC source! Apart from kreg's correct comment, they also change colours at the first plug connection, ref. MR2.
