Wiring Routing Over Rear Shock Absorber

[Phil Waterman]

Hi Eric & Jacques

I had been hesitate to wade in on this until Keith posted the photo confirming the routing along inside of the driver's side frame rail. All my experience has been with Chevy but you might find my experiences useful. (see below for some links)

First and most important be sure to watch the routing around the entire route to watch for rub points where the insulation can be damaged. Use lots of cable clamps to keep the harness where you put it. CMPS are poorly protected from shorts, result burning out harness, and anything near by, is a real threat.

My experience with burning out a section of brand new harness was in the congested area around battery cable, starter, master cylinder, speedometer cable, fuel line, and wiring harness they come together under the floor right under the driver.

Hope this information is of some help, keep us posted on your progress.

Hi Phil and Keith,

As some famous Chinese guy once said "One picture is worth a thousand words"

Thanks for that photo Keith and thanks for the links Phil. Some real good advice and information there for anyone making their own harnesses for any vehicle.

Like you said, Phil, the chance of shorting is high due to rubbing of the wires at many places along the chassis. I have used bitumen impregnated cotton wiring conduit at a number of places to help prevent chafing. In fact Ford used it on their HT wire leads where they cross the engine from one bank to the other and on the coil to distributor wire. I have used it to sheath the wires from the fuel sending units through the chassis to the chassis harness, the horn wire through the chassis, and at a number of other places. Comes in various sizes: 3/16"ID for one wire, 1/4" ID for two wires and 5/16" ID for three wires, plus larger sizes. 1/4" ID is the same stuff used on Ford Fuel lines as a type of insulation. See attached.

Cheers,

..And it is available in all these sizes from Vintage Wiring Harness:

Go to "accessories" then "Primary wiring loom". Not the type of stuff you'd find at the local autoparts store or auto electrician's.

Hi Tony,

Yes, that's where I get it from. Think I mentioned it a long time ago in a post but if not, it's good to let people know. Definitely not a Supercheap, Autobarn or Repco item.

If anyone covers their fuel lines with it, a handy hint is to spray some silicon lubricant on the tubing to make it slide on easier.

Cheers,
