Spark Plug Wire Routing
Can anyone point me to a reference on how the stock spark plug wires are routed on a 93 LT1? I had checked my wires in the dark previously under dry conditions and have since learned I should have misted them down (of course I learn this after I have the whole thing apart and back together again). Well with all the moisture in the northeast, My car was running like crap and sure enough, last night I opened up the hood with it running and it was like the northern lights under there. I currently have MSD wires and they are arcing everywhere they come in contact with metal, not just the boots. I just want to check the routing becuase this car has been messed with so much I dont really trust what was done by the PO.

First thing would be a factory service manual, chilton's for a start. My wires are not in any particular routing order as long as #1 plug is on #1 opti. The drivers side is the real B'tch, gotta go under the compressor
and get it on the right spot. Good wires wont bleed so it doesn't matter what they touch. The opti cap is marked but you can't see it well enough on the driver side

Sorry, I should clarify. I have the FSM, so I know the firing order and where they go on the opti, but my concern was where they are routed between the opti and the plug. Cannot seem to find it in the FSM. Mine are currently; on the pass side they come off the opti under the power steering reservoir, then they are tie wrapped to the heater hoses and lay on top of the frame and then tap off of that bundle for each cylinder. drivers side, they come off the opti, under the power steering pump, and through the AC bracket, then again along on top of the frame and they spli off for each cylinder. I dont have any of those plastic wire looms or whatever they are called. The coil wire comes off the coil and goes up over the water pump and under the air intake to the opti. Is this right or adequate? I also have little insulating booties for the plug end to insulate from the header heat, but these seem to hold moisture, oil, or whatever else I happend to spill on them. Are they a good thing to have or can I ditch them?

Nothing like getting the wires all neat and tacked away, protected and secure like they should be. I dont have the LT1 but its kinda always been a pet peeve to have them all in order.
I like culerd whars too. Where is that smilie with the missing teeth when you need it?
