Sounds like you’ve got a 4-pin quick-disconnect (round) socket on your vehicle — is that right? If so, you can use an adapter like the Hopkins 4-Round to 4-Flat (part number # 47465) to connect your trailer’s 4-flat plug. If this isn't correct, please send me the photo of your socket and I can assist more.

Hey Matt, did the Hopkins 4-round to 4-flat adapter end up working with your Tacoma’s quick-disconnect socket? Knowing how it fit could help others trying to match the same wiring setup.
