[QUOTE=rchase;1277856]Your not "upgrading" the car. Your making an inferior wiring harness that will look bad and may cause unexpected problems with the car. If you can't afford to fix your car correctly and balk at the price of parts why not look at a cheaper car? Would you stick a VW bug engine into it if you threw a rod? Maybee a GM 2 speed transmission if you needed a transmission rebuild?

Who mentioned anything about being able to afford to fix the car? My Jaguar uses a Delco(GM) nitrogen sphere for the ABS brakes, I bought a new one at the Cadillac dealer for 1/4 the price of the holy Jaguar re-boxed part. I guess by your logic, I have defiled my car by using a GM part because I balked at Jaguar's list price.

The Powerglide comment is pretty funny, because the top flight Mercedes 300d Adenaur model used a Borg-Warner slushbox. Likewise the VW bug comment, many Porsche products used VW parts, even complete motors, a la mid '70s 912E. I won't even mention the Posrche 914, because it was only sold as a Porsche in the U.S., everywhere else it was the replacement for the VW Karmann-Ghia.

You don't know how close to the truth you are.

People really don't realize how different car marques share the same parts, with widely differing prices. For example, Mercedes 190SL models and late Porsche 356 models share the same front turn signal lens assemblies. The 356 part is much less than the Mercedes one. Rolls Royce used a GM TH400 transmission in the Silver Shadow model, along with GM power steering pumps and steering boxes. Even the power window motors in my XJ-S are GM parts, down to the GM part number. The issue with the OEM harness reminds me of British planned obselescance and Lucas electrical products.

I think more people are scared of $5000 a/c repairs with the W140, rather than who made up the harness.
