Love my Tacoma

Hello- To All
Proud owner of 2 generation 06' Tacoma. Short version, recen tly I had been charged with a DUI and had to jump through the hoops of the law. Yes, I beat the DUI it was dismissed and sealed. The interlock was installed in my vehicle and recently I uninstalled this device. Now going in and finding out the people that installed the interlock system. Proceeded to splice, cut, and piggybacked off the main wiring harness. I had to go in and cut their wire to piggyback ack off. Regardless to say it's a mess and very unprofessional job. In this tango web I have a wire harness needs to be replaced. I have absolutely no idea and neither does the Toyota parts department. I do know it's connected to my lights and truck doors. It constantly gives a ticking noise. Please help. .. It's driving me insane .... LOL
