I bought an engine harness new from a speed shop (eBay) was supposed to fit my 95 Z28, the coil plug on it is the 96-97 type.. my car is setup as 95 Z28, (with the black and gray coil pigtail) is there a conversion piece? The wires are white,green,red on the harness... and if I remember correctly the 95 ones are 2 pink and one tan......
