Thank you for the help. Very much appreciated. I'm assuming that I will have to gently rip off the black carpet that covers the firewall to reach them.
I've been trying to locate the grounds in the engine bay of my 91 ls400. All I can find for the past couple days are electrical diagrams that don't really help and a thread about replacing them after 8 years. I've only found one that's right next to the fuse box but not sure where it leads...
I've been trying to diagnose an intermittant non start problem on my '91 ls400. I notice that when I start the car, I see a spark from inside the starter relay.
My question is this, is it normal to see a spark glow inside the starter relay?
i have a 92 ls400 and my alternator is about go out. i searched the part number but it seems to be very specific (ls400 only):
F4000-101138 denso
F4000-27357 bosch
just in case the parts stores are closed today, can i use an alternator from something else like a sc400 or another toyota...
