I have 1995 Camaro Z28 LT1 parked in the garage for 10 years. While I was trying to put back some of the engine parts like injectors plugs, I noticed #4 injector wires with plug missing. Luckily, I see a small piece of wire stub coming out of the harness, so I know where the wires go. I believe the mice/rats have taken the whole piece and nowhere to be found. I bought a new generic pig tail with connector attached with 2 colored wires.I plan to solder these wire to the harness stub.Does the polarity of these wires mater or just connect anyway is fine? The other problem I have is that I am missing 2 clips on the injector plugs. Where could I buy them? I will appreciate any help on these two issues. Thank you.
