I found the part numbers for one of the relays(had to sub to TIS) and the tow brake controller. I don't know what that looks like, but based on the location on the diagram I have, I think that is there: T13 Towing Converter Relay 90980–11535 T 8 Towing Brake Controller 90980–11603 I'll post the part number for the other Tow Tail Lamp relay(the one under the hood) when I find it. If anyone else has that, please post it. Thanks.

When I did mine (same circumstances), I had to pop one relay in the from box and one behind the tail light (see the photo, the relay is the green box). A lot of people will tell you that all you need is the relay under the hood, but they rear relay is key. Why? because if you plugged the wiring harness in under the truck, by the spare tire and the relay under the hood, but not the green relay, a volt meter will show weak current when you check continuity at the harness. The green relay is available via mail order at Sewell Lexus. Photo Attached. Good luck! Joe Hello, Does anyone have the part number for these relays? The two relays that are needed, one for the underhood fuse box and other for the tow converter box? and where does the fuse box relay go? I have a 04 GX 470 that was not preped. I got the hitch and harness, but aside from the ground wire, none of the other lines are hot. I only get .01 volts on the aux line. All other are dead, no signals or brakes. Thanks.

Will any of the coastaletech, http://www.coastaletech.com/, lockpicks work on a 2004 GX470? I emailed them, but get no reply, but they seem to be taking orders and shipping just fine from the other posts I have seen. I would have liked to hear from them, but since that is not working, I thought I would try here. I searched, but only found posts from people with 2005s and up. So I'm guessing there is not plug in solution for a 2004 GX470?
