The harness is starting to shape up. Obviously its not done yet, but at least now I have an idea on what it'll look like.

Thanks man!

I finally got the harness completed, installed, and wired up. I built the fuse box myself using the guide on lt1swap.com.

I hope to have the exhaust on it by this weekend. It's just a basic H pipe setup running into two knockoff Flowmaster 40's dumped before the axle. I'm going to get the computer tuned by Frost. Hopefully when that comes back I should have the car moving under its own power!

I haven't had the hood back on the car yet, but I see no reason why it wouldn't fit. The alternator sits below the fenders. It'll be close, but shouldn't cause any issues.

Like the blue engine. Looks better without the vette covers. Jmo. I am doing a swap on a malibu. Almost at the wiring stage. I have a harness from a van. Little different than the truck. I guess I just need to dive in. Nice pics keep it up.

I have seen several people relocate the coils to the firewall or even the inner fender. This allows the valve covers to be seen. Also it gives the engine compartment a cleaner look. You just need longer plug wires and adjust the injector connections. But it looks cool. I thought about doing it my self but my vc aren't that impressive.

Thanks for the props! If I was going to run covers I would fill in the Corvette lettering and paint them up nicely. I'm pretty happy with how the wiring looks inside the engine bay so I don't mind not running covers for now.

Doing the harness is pretty easy actually. Removing the wires you don't need from the harness is child's play. The only thing I wish I did was build the fuse box and OBD2 port outside the car. I jumped ahead of myself and installed the harness by snaking in through a hole in the firewall. So now I had to take the passenger seat out so I can build the fuse box and port. I got it done, just did it the harder way.

I was actually planning on doing this but I decided to just get the car running first before I start dealing with little stuff like that. I do really like the look of the coils mounted somewhere where you cant see them.

Small update:

I'm waiting for my computer to come back before I can fire the car up, so in the mean time I've been completing small tasks. The first was installing new Temp and Oil gauges. I like the silver face on the T/A bezel! I also took a pillar pod made for a 99-07 Silverado and decided to start molding it into my pillar. I took a heat gun and got it to mold to the shape of the pillar and mounted it using adhesive. I'll come back with some filler and mold it into the pillar. I don't think anyone makes these for our cars, so I figured I'd give it a shot. I'll be putting a wideband in it.

The last few pics are the sidewalls of my tires that I sanded smooth. I have big plans for these! I'm sure some of you might know what I'm doing here, but for those that don't I'm planning on running "Billboard" style Good Year lettering often found on Cobra's.

The center air vents are a good location to place your gauges. If you're not running A/C, that is. Just out of curiosity, why not go with stock gauges?

That's where I placed the new oil and temp gauges in the first pic. I like the aftermarket gauges better, plus I didn't have the original sending units for the stock gauges.

Thanks man!

I actually finished the wiring the other day, hooked the fuel system up, put the battery in and turned the key to the on position. The system primed and the DBW throttle works, so I guess I did something right. I need to chase down a few fuel leaks but so far so good. I'm really struggling with getting the factory steel line to seal with the AN line at the flare.

Question:

The purple wire for the starter is just my old one right? I don't have to do anything with the purple wire from the stock LS harness?

I got the car fired up today! Still need to run the exhaust and make an air intake but the car finally moves under its own power again!

Turned the key, fired over within 2 seconds, idled right down and ran smooth as silk. I was actually able to drive it back in the garage instead of push!

I'm working on finishing up my car trailer so I can get the T/A down to the exhaust shop.

Got an earlier opening at the exhaust shop, so I loaded it up and headed down today. I also received my lettering for the tires, and I think its gonna look sick!

Just got back from the exhaust shop. The car sounds very good, and just from driving around the yard I can tell the car should be pretty fun!

I worked on the car a little today. I got the wideband installed, coolant filled and circulated, and got the electric fan wired up and working.

I'm getting two codes. One is driver side overly rich condition, and the other is passenger side lean condition. This is verified through the wideband, as its installed in the driver side pipe and after warming up its reading 10.0 flat. Its steady @ 14.5 afr until the car starts to warm up, then it goes full rich.

Any ideas on where to start looking?
