Disclaimer: I know its 'ricey' and expensive.. but seeing the Meso one, Id rather the authentic TRD one. This would be for the vehicles with keyless start, not adding keless start to a vehicle without.
Looks like the Hilux model fits plug and play:
Part # MS422-00003
5th Gen Toyota 4Runner (2014-21) Push Engine Start/Stop Red TRD Button – KTJO 4x4
Anyone tried it?
