I was going to replace the front o2 sensors until I realized the front ones have a flat 4 pin connector while the ones (I have) after the cat are the square 4 pin. I was told they all were the same. I am not going to splice the old flat connectors on so where should I go to get the correct ones for this? Is this even correct?

Thanks.

What vehicle is this on? I have a 2002 Z28 and all of mine are square connectors.

Make sure the previous owner "did not" use extensions on his wires ( especially if your car has headers). If you have headers then hopefully you bought Vette O2's that have wires longer than 18"....

97 LT1 Formula. No headers, The drivers flat connector is somehow fastened to the toeboard/firewall. It's a little hard to see. So I understand all four of these should be square connectors?

LT1 uses flat connector on upstream O2's, sqaure on rear.

LS1 are all square.
