You will never get that wireharnes working properly again. it is a common problem for that era. There are companies that rebuild the pig tail connecter on the e.a actuater(throttle). Engine wireharnes is probably in need of replacement as well. The insulation for that era of german vehicle is meant to decompose and be enviromentally safe. They have since changed there polidies. I hate to say it but your wasting your time trying to rebuild that harness. Just either sublet your actuater for repair or replace it. subletting is alot cheaper

How to replace ignition tumbler on 2000 ml320 mercedes benz?


i would assume that there is a hardened steel sleeve "VERY HARD" that surrounds the barrel the same as the W140 model. the repair shop will have trouble cutting this off , like the novices at diesel motors in perth western australia. and will probably want to charge you around $3,000 AUD to replace the key and barrel. which collapsed in my case. jamming the key in the ignition. not bad for a vehicle that had cost $219,000 AUD , and had covered 220,000 km, when there countless thousands of 40 year old toyotas and holdens running around with the original ignition barrels. anyway , digressing , the switch that sits behind the actual barrel lock will no doubt fail not long after u change the barrel also. because i would say that the junk they manufacture for these over rated piles of trash (still riding on the reputation of their 1970's products, is about the same quality level as cheap rubbish componentry used in the W140 . "google search for W140 wiring harness there s a blog with a list of owners in the US with failed wiring insulation causing the copper wires to short out and in many cases cause engine fires. manufactured by Bosch to MB specification to be biodegradable, what a totally brilliant place to start , crucial electronic components, with severely limited life from the start.! , the ignition switch doesn't need to be cut out of the steel dash frame like in earlier models, and is not particularly hard to remove however the stealer will still try to slug u around a grand and tell u its a HUGE job. a friend of mine had my ignition barrel and switch out in 20 minutes after the switch behind the barrel failed after the dealer installed a new key and barrel and charged me 6 hours or so at $120/ hour.

I need the wiring diagram for installing a trailer plug for my 1998 chevy silverado


sammy tatz,

There usually is not a diagram for this type of wiring, as it's wired directly into the current wires. You simply need to follow the wires on the truck (if doing the plug here) and run the wiring to these as needed per light.

If you are wiring the trailor - the new wiring harness should be color coded as well as labeled (if new) for each light. Trace the wires (if attached still) and attach each wire as necessary to it's appropriate light.

I have never personally heard of wiring diagrams for this, at least not for aftermarket wiring. Any other diagrams for wiring can be found in a service manual for your truck.

Please let me know if you need further assistance with this matter.

I need a spark plug wire diagram for 1987 ford 302 crown vic


1987 Ford Crown Victoria 5.0L FI 8cyl

Duraspark Type Plug Wires
The spark plug wires used with the Duraspark type ignition system are 5 / 16 in. (8mm) in diameter to contain the higher output voltage. There are two types of wires used in this system, and some engines may have both types installed. It is important to properly identify the type of wire used for each cylinder before replacements are made.

Both types are blue in color and have silicone jacketing. The insulation material underneath the jacketing on some plug wires is a silicone layer separated by glass braid. The plug cable not incorporating the silicone layer is used where engine temperatures are cooler and are identified with the letter SE with black printing. The plug cables with the silicone insulation are used where high engine temperatures are present. These cables are identified with the letters SS with white printing.
Each spark plug cable, if original, is marked with the cylinder number, model year and date of cable manufacture (quarter and year). Service replacement wires will not have cylinder numbers, or manufacture date.


On any vehicle equipped with a catalytic converter, never allow the engine to run for more than 30 seconds with a spark plug wire disconnected. Unburned fuel in the cylinder may ignite in the converter as it is exhausted and damage the converter.

When removing spark plug wires, mark and tag the individual wires. Grasp, then slowly, twist the insulator back and forth on the spark plug to free the insulator. Do not pull on the wire directly as it may become separated from the connector inside the insulator. Special tools are available which can help ease plug wire removal, and prevent damage to a cable.

When installing a new set of spark plug wires, replace the wires one at a time so there will be no confusion. Start by replacing the longest wire first. Route the wire exactly the same as the original.

I need a wiring diagram for the alternator on my 1984 gmc jimmy


I don't have the wiring diagram, but here is how it is wired, the large red lead bolts to the insulated stud on the back of the alternator, the other 2 smaller wires are to the "D" connector, go to a good parts store like NAPA or CAR QUEST and ask for a repair connector for your alternator, it will be a stub connector with 2 wires in it, just splice it to the old wires and plug it in, one wire is bigger than the other so it's hard to screw that up. Any further questions just post a new message. Go to it and lets drive!
