How to Make Proper Automotive Wiring Harness Repairs - WeWrench Instructional Series

#automotive #cars #wiring #maintenance #repair #technician #mechanic #diy

The modern vehicle wiring harness has over 1 mile worth of stranded copper wires and thousands of connections. Compared to a car from the 1950's that had maybe 50-60 connections and 150 feet of wire total! Every single automotive system depends on having a robust and durable circuit to power and control it, making wiring harness repairs and maintenance a critical task for any modern technician!

Welcome to WeWrench. My name is Michael Dey and my goal is create a new car community and platform that deploys the most detailed automotive content and restorations on rare and exotic vehicles. The first video of the series outlines my project car, the dream car of my youth; a 1992 BMW E34 M5. The BMW M5 is a high performance variant of the BMW 5 Series marketed under the BMW M sub-brand. It is considered an iconic vehicle in the sports sedan category. The E34 generation of the M5 was produced from September 1988 to August 1995. There were only 1678 units produced in the United States and out of those, 1992 was the rarest production year with only 121 units imported. Production of M5 models began with the painted bodyshell of an E34 5 Series at the BMW Dingolfing plant. The shells were then transported to BMW M GmbH in Garching, where the car was assembled by hand over a period of two weeks

My project car is painted BMW Paint Code 287 Mauritius Blue Metallic which only adds to its allure and pedigree. Although definite numbers are not known, there could be less than 4 US Spec M5's painted in this Mauritius Blue Metallic and built to this configuration. The E34 M5 has the venerable S38B36 Engine, tuned by the Engineers at the BMW Motorsport division in Garching Germany. The S38B36 is based on the M88/3 engine which has a rich history and lineage in the BMW racing division. Compared to the M88/3, the S38 has a lower compression ratio (9.8:1), simplified exhaust manifold, catalytic converter, dual-row timing chain and a shorter camshaft duration.

I am a former Factory Trained Master Guild Audi Technician and ASE Certified Master Automotive Technician. I will be using all of my skills to restore this vehicle to perfection. In this video, I introduce myself and perform an interior and exterior inspection of the vehicle, and dive into the history, pedigree and story of how I acquired this incredible machine. In subsequent videos, I will restore this car piece by piece, bolt by bolt, and document every detail along the way. The engine and powertrain will be removed. The sheet metal and rust will be repaired, the body panels will be kept original with new body work and paint job.

The S38B36 engine will be rebuilt, the Getrag 280/5 transmission torn down and inspected, rear limited slip 3.73:1 differential rebuilt, fuel tank welded and repaired, suspension replaced, air conditioning repaired, interior reupholstered, wheels refinished and any other pressing issues will be rectified. I will repair both cosmetic rust and structural sheetmetal and repaint the vehicle. This is essentially the ultimate DIY automotive project. I want to put all my skills on display, and share the passion and excitement of having a project car and bringing it back to life. This video should also serve as the ultimate repair resource for the BMW community with special focus on E34 owners. If you own or repair any BMW E34, such as the 518i, 520i, 525i, 530i, 535i, 540i or M5 both sedans or tourings, this video will be the most exhaustive authority on repair techniques and information

Any owners of the BMW E24 M6 and E30 M3 will benefit from watching as well, due to the fact that the S38B35 powertrain and S14B20, and S14B23 powertrain share parts with the S38B36. You will also benefit from watching this series if you own the following BMWs:
