I'm trying to find exactly where the integration relay is in a 98 4runner. I need to test it to figure out why I have no radio, dome lights, or power door locks/alarm. I keep on blowing the dome light - 15A blade fuse and need to find the short/ground. I've tested it between the battery and the 15A. The next step is between the fuse and the integration relay. Thanks in advance.

 

On the interior fuse panel, below the fuses, on the front side. It's the big box that hugs the fuse box, and it is connected with a 12-terminal connector. If you want it to work while you are testing it, you will have to make a bunch of jumper wires to connect it to the fuse block to maintain its connections. Apparently the head nerds at Toyota liked Ford's Taurus idea (4 relays in a box) so much they stuck it in most Toys since 92 or so. They're located in the same spot as yours on most Yotas, car or truck.

 

*Thread hijack* Very impressive Sho510! Your first post as a newb on this board and an informational one. Are you a Toyota Technician or just a big time gear head? Anyways, I just had to compliment you on the knowledge you have.
