The last guuy that owned this car cut the ground wires to the back of the heads.
Anybody know where they go into the fuel injection harness?
89 camaro harness.

 

the only ground wire on the back of the head on my bird goes to the firewall

 

Yev, if you will look on the rear of the left cylinder head you will find about two or three ground wires there. drd930, you didn't mention which engine you have in your car. However if you have a V6, you will have two ground wires going to the back of each cylinder head. they will be a black/white wire and a black wire on the left side and a black/white wire and a tan wire on the right side. if you have the vin f or vin 8 engine, you will have two wires on the right side and one of them will be the braided wire going to the firewall. the other wire will be black/white. there will be three wires on the left side, a black wire, a brown wire, and a black/white wire. if you have the vin e engine, you will have three wires on the right side, again one of them will be the braided wire going to the firewall. The other two wires will be a tan wire and a black/white wire. there are four wires on the left side, a black/white wire, a brown wire, a thick black wire and a thin black wire. Hope this helps.
