New wiring harness options?


KB73

Recommended Posts

My wiring harness is in pretty bad shape and I'm looking at options for replacement.

I've done a bit of searching and it seems like my choices are limited. The original harnesses are NLA, a custom harness (say, from Rhode Island Wiring Service) would probably cost over $2500.

I'm leaning toward making my own. I know a couple of you have attempted this and I would be interested to hear about the process.

Are there other options out there?

what are you driving? I BELIEVE THE TII FRoNT HARNESS IS AVAIL AND SOMEONE HAD A NEW REAR HARNESS A FEW WEEKS AGO (KRIS)???

Yes the front is avail. The rear is NLA, but I do have an extra NOS rear harness.

I'm driving (well, pushing really) a project 73. Thanks for the tip - I did a search for the Tii harness on real oem. So between the front and rear harnesses I'm looking at at least a grand.

When I re-wired the 72 a few years ago I spoke with RI Wire and visitied their place, more for components on my project than the whole harness as I had all ready purchased a 14 circuit micro circuit breaker Painless Performance kit from Summit. If someone had the cake and a desire The RIW folks can duplicate anything including the color(s) and gauge of the wire. Nice people.

The PP kit is first class quality wise. I mounted the fuse panel above the brake booster on a bracket I fabricated and it leans out to the front at about a 30 degree angle. You have to add a number of wires to the rear as the US makers and the Germans think differently about wiring cars. A significant expense is just getting the required style terminations. Get friendly with a Wurth guy. I do have some extra circuits Elec cooling fan, AC) which I pulled up into the area of the factory fuse panel and store them there under a cap I fabricated. The only factory wire I have left is the 12" pig-tail off the wiper motor and a few off the ignition switch.

It was an interesting project that took way longer then it should have but it is now done and all new wire. That is a comfort.

Doing the rear yourself is pretty simple, again, once you source the material, but I'd recommend just pulling the drivers side interior right out. Don't forget to add the third brake light wire.

    BMW Neue Klasse - a birth of a Sports Sedan

    Unveiling of the Neue Klasse Unveiled in 1961, BMW 1500 sedan was a revolutionary concept at the outset of the '60s. No tail fins or chrome fountains. Instead, what you got was understated and elegant, in a modern sense, exciting to drive as nearly any sports car, and yet still comfortable for four.   The elegant little sedan was an instant sensation. In the 1500, BMW not only found the long-term solution to its dire business straits but, more importantly, created an entirely new

    History of the BMW 2002 and the 02 Series

    In 1966, BMW was practically unknown in the US unless you were a touring motorcycle enthusiast or had seen an Isetta given away on a quiz show.  BMW’s sales in the US that year were just 1253 cars.  Then BMW 1600-2 came to America’s shores, tripling US sales to 4564 the following year, boosted by favorable articles in the Buff Books. Car and Driver called it “the best $2500 sedan anywhere.”  Road & Track’s road test was equally enthusiastic.  Then, BMW took a cue from American manufacturers,

    The BMW 2002 Production Run

    BMW 02 series are like the original Volkswagen Beetles in one way (besides both being German classic cars)—throughout their long production, they all essentially look alike—at least to the uninitiated:  small, boxy, rear-wheel drive, two-door sedan.  Aficionados know better.   Not only were there three other body styles—none, unfortunately, exported to the US—but there were some significant visual and mechanical changes over their eleven-year production run.   I’ve extracted t
