Hotrod SWB Harness

[Steve Smith]

Hey all,

I wanted to share a little project I have been working on.

First a little info on how I got to this project. I was contacted by a gentleman who is building a hot rod SWB 911. If I remember correctly it is a 68. I don't remember the exact engine but he wanted something special when it came to his harness. At first I was just going to do a standard harness with some high heat expandable braided sheathing. Then we started talking about Raychem DR-25 and that ended up leading to Tefzel wire. And THAT ended with me rethinking a few things and changing a few things.

Now the above described harness was something completely new to me as I have tried to make my harnesses exactly as Porsche did. But, even though we all love the Porsche brand, I think we can agree that Porsche's wire management on the SWBs was not real great. The wad of wires coming out of the harness near the fuse panel, stuff just kind of hanging out there, unfuse circuits, etc.

So I came up with the below. Some will say that the Tefzel is overkill. It is. Some will say the DR-25 isn't necessary. It's not. Some will say that if Porsche used it for 50+ years why change it. And I was one of those that said that loudly. But sometime ya just gotta say screw it. If the cars not going to be original than lets go deep. So below are some pics.

As you can see we used the Refuze panel from Alan. Fantastic product. Actually used 2 panels with the second being a 3 fuse panel that allows for fusing of some of the unfused circuits. The metal sub panel moves the panels over a little so that there is plenty of room for wire routing and to help stabilize the wires. It also gives a place for the 3 panel to be mounted.

As you can see what we tried to do was to route the wires to their corresponding direction. With dash area up. The front stuff down the right side and then the stuff for the rear down the left. The customer did want a few things left off so there are a few wires missing.

The whole harness was done in Raychem DR-25 and then the junctions were sealed with Raychem SCL.

The first pic below is what we're used to. Then 2 pics of the new panel area, then 2 pics of the DR-25 and SCL and the final one is a test fit.

Much , much neater, and I'm assuming all done to correct wire color code so that a future mechanic will be able to trace circuits using original schematic. We always love diagnosing 'home' done wiring using one color of wire and loads of butt connectors!

Looks great Steve .... And I would be willing to bet that it is color code traceable.... great work.

Thank you!

Thank you sir. Yes. It is all correctly striped/color coded wire. Just it's Tefxel wire with a different routing and the addition of the 3 fuses.
