Wiring Wednesdays!

[Revved]

I think this post is great for the guys that think their wiring job is a nightmare. Look at a picture like this and realize that no matter how bad you think your wiring job is- someone always has it worse!

Congrats on the wiring- The finished product will be worth the time!


I just pulled the dash on a 70 Chevelle last week that had an alarm system, Dakota Digital dash, Vintage Air with Electrical Controls, and an Accel DFI system, all poorly installed with butt connectors and splices everywhere. It was such a mess I literally had to cut the dashboard out of the car!

Revved, I feel your pain!

We had a custom bring in a 49 ford for a vintage air install, and there was household maurettes for connectors under that dash!!!! we had to rewire it.

Just take the time, do one circuit at a time, and use good quality connectors and stay away from those cheap insulated butt connectors!

I want to hear some feedback from someone that has used ISIS. I want to put this in one of my clients cars..... but I still haven't heard alot about it. Anone use the new touchscreen from them?

looks like what i'm dealing with. '01 camaro into a '69 camaro. i'm keeping almost everything though so there is a lot of rewiring of the harness to move stuff around to fit.

Got the ctsv harness down to the bare essentials!



And this is what it gets finished to as it goes in piece by piece, in sleeving and heat shrink.



and our AMP connection for the Mast motor harness, and the tci trans harness will be next to it

Whoa gott give you guys a hand for doing such a great job on harness . Mind post a few pictures up of the style of connectors not to use and correct style to use? Sure it will help a few people out there. I never heard much brought up in terms of if you solder any wires or conectors. Also like the look of heat shrink of the sleeving .So did you buy a terminal tool to remove wires or make up something on your own (post pictures) Just wanna thank you for posting all this wiring info up for us.

All the connections we make to our accessories are gm style weatherpaks. they come in single to 6 pin connectors, and you just need a delphi weatherpak crimper to use them. The engine harness plug at the firewall is called an AMP connector by Tyco, and it uses a special crimper (600 bucks if you buy it new, but you can find them on ebay) The AMP connector has 63 pins, but you cant send amperage through it, so its for signal wires only.

All the power leads run through a 22 pin bulkhead connector that uses weatherpak terminals, from American Autowire.

I will take some closeups for you.

the sleeving is called Techflex. we became a dealer for them and stock spools of all kinds of sizes, inlcuding a real slick split style loom that is braided and overlaps itself. This is great if you cant get the connectors off, or if you have leads exiting the harness everywhere. The non split stuff expands to 300 percent its size to slide over the wires.

Theres a juicy tidbit for you. NO more convoluted plastic loom guys!!!!!!!

you can also get metric pack connectors that the newer GM's use. i like those a lot more than weather pack since i started using them.

I came across this old thread on a Google search and figured I would update the fore-mentioned project! It was just completed and delivered at the end of summer. The client flew out here to DFW and we road tripped it 2200 miles back to his home.

As mentioned the wiring was so bad that we ended up gutting the entire vehicle and rewired it toe to tail with an ISIS Power system with their InMax touchscreen. Power windows and Power locks were added. Stereo was upgraded to a touchscreen nav system so everything in the vehicle is now touchscreen operated. Underhood we had plenty of electronics as well with intercooler pumps, MSD, dual fans, etc...

First here was a shot of behind the dash...


And then under the hood...


And the firewall after everything was removed...


Here is a shot of the trunk wiring going together..


And the Dash wiring going together...


And the underhood wiring going together...


Here is a shot of the underhood in final assembly. All wiring and plumbing hidden...


Shots of the interior assembled...




Final engine bay shot.



Happy Wiring!
