Once I found the drivers side fuse box this thread was fantastic. I replaced the ECU fuse and my problem was corrected. I also know why the blew the fuse.
I am dissatisfied with the reception with the factory power antenna so I decided to install a small high-gain antenna. The antenna needs 12v so I was looking around with a meter for a constant 12v. Never did find 12v.
This is my first post but I have used this resource a few times.
I bought my first Lexus, a 1997 LS400 with 153,000 miles, a few weeks ago and I am hooked. I can't wait to get a newer one.
