I am trying to put my plug wires back to a stock arrangement and need some good up close pics of what goes where in terms of how the wires are routed through the wire looms. Thanks

I took these at the Corvette Museum.

Elrick

Perfect, Thanks. so thats what exhaust manifolds and covers really look like. wow

I'm using this pic to set up my wires and I think they have the wire for the #8 cylinder going into the #6 cylinder. That's funny that this is in the corvette museum, unless I am seeing things. which is a good possibility

Good catch! Also, I thought the LT4 came without EGR tubing?

No it doesn't, it is installed correctly. The opti spark cap does not work on order. On the left side (is not from the bottom up) 2-4-6-8



That's not the EGR tube, LT4s has no EGR.

Next time, if you google "opti spark firing order" you will get faster results.

Let me know if this helps (at the end of the video is a wiring diagram):

Good Luck

I think its set up properly but if you look at the number that is on the wire going into the number 6 cylinder, it looks like it has an 8 on it. I just think that maybe they used a #8 wire for the #6 cylinder thats all. If so, its kind of funny, being in a corvette museum.

Hey Dogfish, love your videos. wish you had one for a steering rack. just got done doing mine and although it wasnt hard it always helps to see it done first. Thanks

dogfish246

Thanks! I fix it as it breaks so when my steering rack breaks, I will make a video (disclaimer: this might not happen for a long long time )

I'm old and have bad eyes but I think you are right 8 and 6 are swapped.

OP is talking about where wire #8 ends. Trace it - it goes into cyl. 6.

I've looked at it for 15 minutes. Kinda funny and possibly some kind of joke that no one has caught.

Elrick

Okay, at least now i dont feel like a total idiot. When routing the wires iwas referencing these pics, which I do appreciate, thanks, but they didn't make sense and I was thinking that the corvette museum can't be wrong. I know its just a small mistake

RollaMo-LT4

Yeah, in looking close it sure looks like 6 and 8 are reversed to me too.
First time I've ever paid much attention to it.

I took the pictures and I have looked through all my files for a better quality close up, but those are the only ones I have.

I think they did a good enough job for the routing, with only that 6 and 8 being reversed.

yes, the pics made it easy and thanks so much. The po had after market so I had no idea. The only reason I picked up on this is the tangled mess I had before your posted the pic. I only wish my engine still looked like that one

Too bad you can't see the plugs or wires that clearly when the engine is in the car! I dread the thought of having to change mine eventually.
