    For those of you who’ve done it, what is the best and cleanest method to wire (3) light bars on a 25 Platinum hybrid? For a Mother’s Day/birthday gift my son got me the OEM TRD Pro grill and marker lights. And since everything was coming off already I also added DD upper & lower light bars and swapped the OEM fogs for amber DD’s. But now I’m not sure how to wire it cleanly without causing system errors. Or rather how my husband and son can do it. Where to order OEM like buttons? Would a control module be best? Should I just take it somewhere?

    For the cleanest look I would definitely take it somewhere. They will have all the materials to get it done and know the best method. If you want to try and tackle it yourself you’ll need several of the write ups on here to do that. Just search each of those items you’ve listed and someone has made a write up for it somewhere. If not then you can post back here with a more specific question and we can try and find a solution for you. Just quick notes on what you’ve mentioned above. The marker lights you can run a wire harness with an add-a-fuse and run that to one of the fuse panels under the hood to make them function how you’d like them to. For the grille bar because it wasn’t a factory install you’ll need to source a wire harness and that will require a switch as well unless you want that to be tied to another function like only come on when high beams are used. For the other bars it’s the same exact thing. If you’ve never done anything like this before make sure you do your research before starting this project. You do have the ability to permanently mess up your truck if you don’t do it correctly.

    Thanks and I’m definitely not doing it. I was having anxiety with the plug n play fog lights because I read those could cause system errors. I want one of the bars to turn on w/high beams and if possible, marker lights with fogs but not sure.

    A buddy and I just recently wired up the TRD marker lights and DD light bar on my 24 hybrid platinum. For the marker lights we tapped into the fuse box on the passenger side. For the light bar we tapped into the right fuse box and ran the wire through the firewall and added a OEM like button on the existing dash. The wiring DD supplies for the light bar is plenty long enough and you not have to connect to the rear battery.

    total grille conversion and lights took probably 2-3 hours.

    It’s very lean and bonus is I can turn on and off the light bar while driving if needed. I’ve heard from factory you have to be in park.
