SR;
The oem in-line fuse holder will be on the red/power wire close to the TM batt connection, probably one of the glass fuses, that is what I had on my 04 tracker. Just follow it back and you should find it within a couple feet of the battery connection. It's an in-line connection and when I removed the fuse to do the install, the fuse/connector was corroded, so I junked it and got one of the re-settable ones from my local dealer for $8. The link in BB's post is very similar to what I used, so if the TM pops the breaker for some reason, just hit the re-set and keep fishing.
You will have to cut the oem fuse holder off of the power wire, install a ring connector and then make the connection. You may or may not have to make another short jumper wire with ring connectors to make the connection to the TM batt depending on the type/style of new breaker you get.
GO BIG ORANGE !
I meant to behave, but there were just way too many other options available at the time.
