    sourcing wire

    I'm trying to find correct wire for replacing old/worn wires in a BMW wiring harness. Anyone happen to have a source for wire in the correct color codes and gauges?

    I'd think of Motobins or Huckys spare parts for new wire or EBay, moa flea market or IBMWR for used a used wiring harness.

    If you are looking for a single wire of a certain color & guage, try a forign car salvage.
    BMW, Mercedes, Audi, Volkswagen.

    If you're blessed with a /5 or older, you can buy an entire wiring harness (engine, main & subframe) for around $150. You need to be aware that the actual gauge of the wire is slightly smaller than the 40+ year old stuff. /6 and later.... not so good; $650+

    As mentioned, a fairly good source for "single" wires might be eBay; I frequently see wiring harnesses offered. The chances of the particular wire color you need being tact are probably pretty good.

    I was specifically looking for the correct size and type, with correct color codes, I was going to roll my own.

    Given the colors offerred by Las Vegas I'd conclude it's not really oem wire.

    Good to remember that OE wire is not "gauge" sized but rather sized in millimeter cross section.

    +1 What Kent said.

    I don't know who is making the "new" harnesses. The one I bought came from Bob's BMW and the diameter of the conductors is smaller than those in original harness.

    edit - I didn't spend any time looking at those wire colors when I posted that. Most are not BMW related colors, others are not present at all (blue/red, red/green, etc.)

    to clarify, it doesn't have to be an -exact- match.

    It needs to be of equal thickness, or greater.

    It needs to have the same color patterns, but not the same shade. so long as it's 'blue with a red stripe' the colors don't have to match the factory. The idea is that some other poor bastard can look at my work, look at a manual, and figure it out.

    This is the closest I have found: http://www.prowireusa.com/Mil-Spec-Wire/departments/74/

    Not the exact same color locations, but the same colors (i.e. blue/red) can be used on a specific wire. The original metric wire has a specific diameter (which is in mm) but I have yet to find an instance where that dimension is critical. Good luck!

    My local Napa has Arctic grade wire,flexable at any temp.and in many colors and sizes.IMO much better than the brittle stock wire.

    I just spoke with John at Benchmark Works (yes, they are open on Mondays). They do not have, nor do they know of, a source for new, bulk, BMW OEM color-coded wire.

    Rusty Gill (MAXBMW (NH store) guru) would be my next option, but they are closed on Mondays.

    I know it's an "out there" suggestion, but just remember that ALL German vehicles use the same wire color coding, as it's the Bosch/DIN standard. Therefore a fairly high end restorer of Mercedes may have a wire source. Point being, just checking motorcycle sources is a bit limiting.

    Given what lKchris said, perhaps an auto scrap yard with German vehicles in it would be worth a visit.
