Is this the right diriveter valve for my 91 Z/28 350? I noticed in pics that most of those d valves have a perforated box facing the front of the car, but mine doesn't have one.



Also these wires. I think the 3 red wires (2 are connected) go to the starter?
The white connector goes to the knock sensor, The thick purple wire thats cut I have no clue and the last connector that looks a little burned and is patially missing I thought went to the 02 sensor, but I noticed my exhaust manifolds and the hole for the 02 sensor is on the left one. Are my manifolds the right ones for my year Camaro?

 

The red wires are fusable links that need constant 12 volts. They go to the large post on the starter where the large positive battery cable goes, OR you could run them to the positive post of your battery.

The purple wire is from the ignition switch and goes to the smaller post on the starter to trigger the starter solenoid.

I can't I.D. the odd wire from that picture. If it goes back into the harness for the gauge cluster, or to a fan relay, then it could possibly be the temp-sender or fan switch wire.

 

Thanks for the info. Hopefully I'll get some more input on the broken plug and the D valve. And the wire on that one is grey.
