Soy based wire coating?

Mercedes used soy-based wiring insulation on many of their models back in 1993-1995.
I worked with a guy who worshiped MB. "They don't put anything into a car unless they know everything about it.
They don't experiment"; always words to that extent. He was "brand possessed".

When that insulation became common knowledge, we gave him a very hard time.
 
I think most modern cars do? I see frequent posts about wiring damage from rodents on GM EV facebook groups. So it's not just Honda.

I know a guy like that too. I told him "pimps appreciate loyal hoes". He did not like that one.
 
He did you a favor, those things are so bad, pure sugar in various consistencies, I wouldn't eat one unless I was going to run a marathon.
I think they have the same coating as the wire. I ate them back when I was young and could consume a million calories a day and still not gain weight. Those days are gone.
 
A clone of the Honda Rodent Tape is also available at Amazon. It is made by Teraoka of Japan...who actually supplies the tape to Honda.

Rodent Tape
Haha, you can actually see the "Teraoka" name on the images bcardinal posted. I was expecting the Amazon option to be cheaper, but as I recall, the official Honda stuff is around $40/roll too. Awfully pricey, but if it works, it's easily worth that amount !
 
I was looking at getting a new honda civic SI and apparently they still use soy based wire coating.
Is everyone using that awful stuff now? Any manufacturers that dont?
Better than the 90s Mercs that had self dissolving wire insulation. You can get peppermint essential oil and spray your engine compartment every couple weeks or month to keep the rodents out.
 
Mercedes used soy-based wiring insulation on many of their models back in 1993-1995. They did this in an effort to make earth-friendly biodegradable insulation. Unfortunately, my 95 E320 had this wiring. The problem then was the insulation would biodegrade from the heat of the engine early on in its life. I had to replace it at 7 years because the insulation looked 200 years old. The wiring cost $1000 for me to do it myself. Mechanics would refuse to diagnose driveability issues if the wiring wasn't replaced. They stopped using it after 1995.

Volvo did the same thing. Twice I had to replace one of the under the hood wiring harnesses. Thankfully it had what I'll call a master connection on the firewall, which greatly eased the replacement process.

There needs to be a huge federal law at least in this country that, any sort of rodent destroyed plastics on any car or home, has to be fixed by the manufacture there of, no matter how old or not the items are. I just bet they would then strive to not have this happen.
All those Mercedes should have been a life time recall all on Mercedes dime.
 
My car is a 1999 model year car. You would think that rats wouldn't be interested because the plastic isn't soy based. So they ate part of the battery casing (which might be soy based??).
 
I have a massive white oak in my front yard. Literally dozens of ground squirrels and regular squirrels used to scurry all around collecting the bounty of acorns in my yard. About two years ago nature reset the equilibrium as a large red hawk took residence around my house and I rarely see them anymore. FWIW, knock on wood, I’ve never had any issues with chewed wires in my vehicles.
 
Please, no !
Its like smoking in restaurants, airliners and other places us nonsmokers are in (yeah just had to suffer or avoid in the 50's and 70's, and farther into 2000 ish it fully ended I think), it takes some stupid law to fix the problem.

I'm sure someone could make nasty tasting plastic.

If those critters are just chewing normal old mineral oil made plastic, then shows you how safe that demonized oil from the ground really is. :ROFLMAO:

Government regs are at least partially behind this by encouraging more use of renewables and recyclable cars, at least in Europe...not sure if we are there yet with regs on the lifecycle management.
