anyone know?? i justy need to know if they have the same connector?

I know on the LS2 cars they're different and I believe they're different on the LS1 cars too. The rears are flat connectors and the fronts are square.

You are correct Orion, the rear have a flat connector and the fronts are square.

I'm almost positive the front and rear plugs are the same on the ls1

Sorry mark but you are incorrect. The rear have a flat 4 plug and the fronts are a square 4.

Thats funny that you actually went and looked. I cheated and got on my parts link I use at work and looked at them.

lol yep fronts are small and square and the backs are flat and square,then again most tuners have the back turned off.
