no they didnt. I needed to get the plug and play wiring harness from summit racing. Like I said, it was 50$ for all 8…so for 6, you looking at less then $40 shipped to your door. No splicing wires and its all reversible.
however, stock GTP’s might be the same adaption as yours sense they are based off the older style harness, compared to the newer style like on my camaro.
not sure if these are the right ones for your application but this gives you the idea of what im talking about…
