You got it for a good price. My "Stealer" wanted $245.00 for a new one.

I turned on the head lamps and put a volt meter across the fuse. No power. Where do I check next? missing relay? No reply from the person that was offering up wiring diagrams. I did buy a Haynes manual. It has wiring diagrams but not one that has the optional towing package.

THank you - I will pull the fuse and look for voltage. I already tested for voltage at the pig tail and got nothing. The pig tail plugs into a converter box - I'll try there also. I'll post what I find in the event someone else has a similar problem. Thanks for the wiring diagram link. I requested those the other day also. Nothing yet. I see I can buy the wiring diagram on E-bay if necessary.

I need the wiring diagram for my trailer harness that isn't working. It would include the turns signals and a converter box that the trailer harness plugs into. It would be nice to have it all the way to the fuse box for troubleshooting. E-Mail is Troy.Conwell@ngc.com Oops - 2004 Lexus RX 330 Thanks

I did a continuity check on the fuse but didn't do avoltage test. Can I check the voltage by turning on the lights and putting a VOM across the fuse? or do I need to pull out the fuse? IWIll the headlights provide a voltage across the fuse? Thanks for the help

I have a 2004 RX 330. It has the towing package. I found the connector for the trailer lights and connected it but there isn't any power. I have checked the fuses - they are all OK. I pulled out the converter box that the trailer harness connects to behind the drivers side seat. I noticed there were a few diodes there and checked them. They seem OK. Anyone know of anything else that could be the cause? Software upgrade required? Bad converter assembly? I haven't been able to locate a schematic of the converter to see what all it controls and where the input and output from the turn signals is.
