How problematic is the now 50 year old wiring? Some existing threads seem to suggest they're pretty vulnerable, yet I don't see wiring harness included on most "while the engine is out" todo lists.
Are there any that are consistently so troublesome that they should get proactively replaced even if they appear good? On the 914-6 it appears there are two for the engine bay (complete engine and alternator). That's $500 USD right there. For reference, I'm not attempting a complete restoration. Just trying to get our car safely and reliably back on the road. The engine, transmission, and suspension components are out of the car. I've found a couple previous owner wiring additions, but they have been easy to remove. My impression has been that if the wiring, insulation and connectors look good they probably are good. It's not like the copper wears out. Perhaps this is naive. P.S. New plug wires are already obtained. I have no intention of removing the main harness. |

I have seen a lot of old wire harnesses and they all end up being very different. Some are still soft and pliable, some crack and break just moving them around. It really depends where the car was located and how the car was stored. It’s very similar to car interiors.
I would say if it looks good, feels good and works, don’t fix it. If a close inspection shows cracks and issues around the terminal to wire connections, plan on a replacement. The good thing is, if you need a replacement, there are multiple sources. None are cheap but at least it’s as easy as checking a box and sending payment. (IMG:style_emoticons/default/beerchug.gif) |
