Re: Wiring Harness Routing

Wondering if you found an all inclusive harness installation / routing diagram?
If not, I plan on pulling all the bits and pieces together into one document.
I sure would like to start with something other than the segmented sections from all the books.

I am referring to physical routing not schematic diagram.

Thank you in advance.

Pa,
Most of it is pictured in Bruce Palmer's resto book.

Re: Wiring Harness Routing

This is true Robbie. Bruce covers much of the visual routing. There are a few wires which are difficult to discern though. 42WLA Yahoo Groups show many colored wire routing views during one of the members restorations but one must be a member to view them. It is also difficult to navigate the group software to locate them. This is because much of the data posted is linked ownly by member name. To find much of the data on the group site, one must look over all of the folders until they come across what they are looking for. Dave has restructured the group into easily navigatable folders but most of the membership have not moved their data files and picture files into those folders.

Re: Wiring Harness Routing

Thank you Bruce.
This is happens to be where I was having trouble.
Notice the cable going OVER the base plate to the switch. I need to ensure the cover panel goes on when I route mine.
May need some fusion tape for the sharp curve.

Re: Wiring Harness Routing

Hi Brendon,

The tail lamp harness will easily clear the cover.

Here are two photos from a different 42WLA. It is on the lift right now having its rebuilt engine installed. The taillamp harness is in basically the same location as in the WLA above's photos.

When I run a harness (this also applies to control cables), I will lay it out on the frame loosely and mount one tank and check the clearance. I will then take that tank off and mount the other side and reverify that all the harnesses and controls clear properly.

Sometimes, when I am dealing with a setup I am not familiar with, setting only one tank on will reveal the routing locations that H-D intends to be used.

I also do this to verify that the tank itself is fitting properly on the frame (touching only at the mounts and not rocking between mounts). If necessary, I will add a 0214 washer between the tank and frame to give it the right clearance. I might also do this if the tank is pinching the harness and the harness is in its right spot.

Re: Wiring Harness Routing

Thanks Bruce

I had it routed wrong. I also had more of a birds nest in the dash than your picture.
I'm re-doing it.

I will definitely check that the tank doesn't squeeze my cables. I would have assumed the cable cleared the tank and I would have wrenched it tight creating a short. I see in the picture there is a slight compression on one of the cables.

Thanks again and thanks for pulling the Haley Davidson history into the future with your books.
