running wires under the intake?
running wires under the intake? Has anyone done this with success? I like the idea of hiding the wires as much as possible, and since I am building the harness, it wouldn't be a big deal.
I am just wondering if it is a good or bad idea. Any thoughts?

Gm has done it with success. Knock sensor wires are under the intake on gen iii. How many other wires will fit under there and how big of bundle is hard to determine without trial and error. If you cut down the reinforcement ribs, I bet it would work for most of the wires. Just servicing the harness would be PIA. Or you could be lazy and get a set of Corvette fuel rail covers. LOL

I have thought about covers, but space is tight and I have always thought covers were a lazy way to clean stuff up. haha I will pull the intake off today to see what kind of clearance I have to work with.
There is enough room between the intake cover and intake to run wires. The temperatures should be lower in this area than under the manifold. I gave this a try and it seemed to work okay, but I ultimately decided not to do it because R&R of the intake would be a pain. Here is a photo:
Instead I decided to run them on the top next to the fuel rails. This isn't quite as hidden, but I can easily remove and reinstall the harness when needed. Here is a photo:

I like that idea alot! But I have an LS6 intake with no cover.
BTW Bandit, I read your entire build thread and your attention to detail on the wiring has inspired me to put that kind of detail into my harness!

Here's an idea. Don't know if it would work though. I think the flat space between runner by injectors is solid enough. Could you drill through there and fish wires up?

Verdad Gallardo That may be an option. I am ok running the injector wires up top because I need to run the coil wires there anyway. I was thinking of running stuff like MAF/TPS/Alt/etc. under the intake.

Clint,
Never thought of doing it that way. Great idea.
I plained on running some under my intake and want to run the injecter wires were the recess in on the head. I bought some heat barrier tubing like the knock sensors use a few years ago.

The coil brackets were just some 1/8" steel, some 1/4" x 1 spacers and some 1/4" carriage bolts from Lowes. I looked at putting them down low, but I like where they are as it has a little of the SBC feel with the plug wires wrapping the side of the valve covers. My primary goal with them was to hide all the wiring and connectors going to the coils. I am OK seeing plug wires.
Below is another hidden wire example where the wires are just carefully hidden under the fuel rails. More info in this thread: https://ls1tech.com/forums/conversio...g-my-ls44.html
