Trailer Wiring Harness 01 Tundra

Tunnelratt · 09-14-07, 08:46 PM

Normally hang out in the 40's forum but have an issue with my Tundra.
When I bought it in 01 it didnt have the trailer package, got the 4X4, all the other bells and whistles, just no tow package, 100K miles later, I want to tow, so I find a class 5 hitch in the junk yard, works great, now I need lights, WTF, there appears to be 3 different components, 1 is the converter, it mounts behind the left rear tail light, 2 is the sub-wire harness, this is the pigtail that you would connect to the trailer plug, I undrstand both of these and can find the loc to plug them in, so no problem here, but the 3rd component appears to be some kind of fusible link box that mounts to the positive post on the battery, here's my problem, what does that part connect to? is there part of the harness under the hood that this plugs into? it appears that this fuse box needs to have a ground and a positive lead that goes somewhere to energize the trailer lighting converter.
Camping World said they would do it for $500'00 KMA! Dealer parts around $200.00, I figure if I go to the junk yard, $100.00, has anybody done this install, I just want to throw some magnetic lights on my 40 and flat tow.
Thanks in advance for any help.

The fusible link component is the component that taps the power from battery. The Tundra towing package was designed so that the trailer is powered from the fusible link and not the tail lights.

I like the power tap design so much I adapted it on my 80.

Thanks for the pic, I ran around to all the junk yards and nobody had all of the components, so I bit the bullet and ordered the factory parts, picked them up today, seems like a

job, gotta get ready for a trip to Mammoth, towing the 40, need to be legal traveling up the 395
