Test fitment success! Pardon my Gorilla tape mount, I need to fab another clamp to support the under-body hose.

Very clean and tidy! Why don't you get a spare thermostat just in case yours fails and you can't find one for that housing in 10 years?

@Krieger Andy, the good news is that these in-line housings take standard Chevrolet thermostats so no worries about sourcing a replacement.

The other news is he doesnt really need one. With the electric water pump he can just shut the pump off till the car warms up. Or put it on a temp switch.

The front battery brace is plug welded to the fire wall's arched cross member.
I added a small triangular brace on the underside to provide a bit more support.

Then I realized I needed a place to mount the main harness fuses and after looking at things, I decided to redo the rear battery tray support, making it a suitable location for the fuses.
It was also an opportunity to use the spot welder. It does a great job so again, any local folks who could use it, let me know.

All done with everything in place, and with the fuse covers snapped on.

Time to start on the wiring...

The manufacturers do not put that level of attention to detail into their designs. (IMG:style_emoticons/default/beerchug.gif)

The engine harness is WAAAY too long. So with it now labeled, I split it almost completely, untangled it, then grouped the wires by sensor and/or location of sensor on the engine.

I'll secure things a bit more to make it easier to handle, plug it into the ECU and get started on routing.

Getting the harness rough fitted wasn't as bad as I thought it might be. The part I'm happiest about is that nearly all the wiring will be hidden and all that will be visible is a small sub-harness there at the rear of the engine.

It looks messy now but once that bundle is terminated and connected, I think I can get it to be pretty tidy.

@RetroRacer Tony, I just know you're dying to come up and help! (IMG:style_emoticons/default/biggrin.gif)

Looks like your harness was created in the Large Hadron Collider

I worked up a new dash panel that now includes a neat little raised area for the gauge lighting dimmer knob. Yes, the pic is a repeat of what I posted in the "...SpeedHut gauge panel..." thread, but some of you may not have seen that. Thought you might want to see it here.

Another example of what must be a "worse before it gets better" situation.

This is my first go at building a complete electrical system and I opted for the "lay out all the wires where they need to be" approach. Clearly, I'm not quite there...!

I'll let you know if it works out! (IMG:style_emoticons/default/blink.gif)

Chris, thanks for the inspiration. With my car body off to the paint shop tomorrow, one of the next things on my list is to lay out, clean, and check the wiring harness.

Instead of working on the wiring, I somehow got distracted by just how unattractive I found those strut top washers. They were BEGGING for some style points and for some lightness to be added.

I worked with Martin on this and V1 was trying to clamp the washer directly to the rotary table on the mill. That wasn't working so I ended up plasma cutting a couple 1/4" steel donuts that got tacked to the edge of the washers and served as a workable clamping surface. They worked perfectly!

Before and after.

Sorry @Rand , I just can't seem to focus on "get it running, then worry about the fancy stuff."

But I do have to say, they look pretty cool and I love the way the Elephant camber plates can now peek through.

OK, I'm back to the wiring, I promise.
