Hey Mark,
For your 2012 Lexus RX 350 there are not any 7 pole plug and play options, but what you could do is use a plug and play 4 flat harness with a 4 flat to 7 pole adapter.
The plug and play harness for your vehicle depends on if you have a factory tow package or not. If your vehicle does have a factory tow package you will want to go with # 56083, Curt T-Connector Vehicle Wiring Harness. If it turns out you do not have a factory tow package you would want to go with # 118478, T-One Vehicle Wiring Harness. Any 4 flat to 7 pole adapter like # 37185 will work with those wiring harness's giving you the 7 pole connection you need.
Do you already have a hitch on the vehicle, and just needing wiring?

thanks for the update Nick. I installed an aftermarket hitch...not sure, but I may have purchased it from you folks. so I will need a # 118478 and a # 37185. can you quote these here for me, or do I need to dig into your website to find this? appreciate the update!
