Hey guy in doin a grs swap in my car and im curious to know if the sr5 underdash harness is the same as the gts harness thanks please reply

The GTS contains the circuit opening relay for the fuel pump and the wiring to the instrument cluster. Keep in mind that the GTS cluster uses a check engine light as well as an additional circuit from the speedometer head to send an electrical vehicle speed signal to the ecu. In other words, you'll need a gts harness. When you acquire a GTS harness, it'll install just like the old sr5 (meaning the gts & sr5 has similar relay and a module that clip in to the same bracket) that includes the junction box on the right kick panel. I hope this help.

All harnesses have there little differences. You will need GTS harnesses.
