Yes. the black ones are for the "current" and the green one is for ground.

I personally would replace the block heater,
so you have a safe & working item & the proper
connector on the end

Only other option, is look at a wiring diagram
wherever you can find one

Have to verify your info, if it is not an OE Factory
Wiring Book or reference source

I am looking for the location of the block heater plug on a 1997 Golf diesel, thanks

There is no specific spot for a block heater. A block heater can be in any location the block currently has a freeze plug in. You'll need to look over the block carefully - you will see several round "ports" on the block and one of them will have a wire coming out of it. A freeze plug looks kind of like a small dish in the block, whereas a block heater will look more like a flat plug with a wire. It could be on the side or back of your motor - rarely is there room for a block heater on the front of a motor. Look in the front grill or in the general area of the radiator and you should see one end of a male electric cord( like the end of a lamp cord you stick in the wall ) . Follow this wire to the engine and it will lead you to the location of the block heater. You will probably need an inspection mirror and a flashlight to find the other end ( in the block).
Hope this helps!

1983 mercedes 300d turbo diesel automatic electrical problem

There is a junction block about 6 inches in front of the battery on the fender, there should be battery voltage on the big wires. The small wire is the starter solenoid. Front the junction block, the power goes to the light switch then to the ignition switch.

Good Luck

My diesel is difficulty to start on cold cold days. it also will have a large amount of ssmoke after cranking

First, for poor starting from cold, you need to check the heater plugs, to do this, remove the wiring to each heater plug, then get a piece of wire/cable and get another person to help, you need to hold one end on the top of the heater plug, where the wire was connected, and get your assistant to flash the other end of your wire on the positive terminal of the battery, now, if there is a spark, then that heater plug is ok, if there is no spark, then that heater plug is faulty and should be replaced, do this to all heater plugs, and replace as necessary. Ideally , if just one is not good, then i would advise to replace all..
As for smoke from start up, all diesels will smoke on initial start up but it should clear when warmed up. However, if you have constant smoke, presumably black smoke, then you should check the air cleaner and hoses first, that the filter is clean and that the hoses are not blocked, split or collapsing when you give a bit of revs to the engine. The next step would be to check the fuel filter,if it has a drain plug, then undo that and see if the fuel is discoloured or you see any debrit coming out, it would be wise to change this , unless it has been changed recently. If you still have smoke, then you need to get the injectors checked, this can only be done by a diesel fuel workshop. Hope this helps

Replacing 3 pin plug on block heater cable 2003 impala ls. what wires go clor wise into plug

i think you are they should be color coded and match up directly .....however if you changed the wires completely they i would suggest find another 2003 Impala and either photograph it or write the sequence down a dealership will allow you to look at the motor even if you have to pretend you want to test drive it or just look it over
