wiring merc 300ce

wiring request Merc 300CE

hey guys im in need of a wiring diagram for merc 300ce for the central locking ( pump)

i know the wires to hook up for central locking but need the wiring for the pump it self

       there is a 3 pin plug ( only 2 terminals needing to be used )

       and their is a round plug with green, blue and yellow, not sure what spots they are supposed to be

     any help would be great thanks

The green blue and yellow are the control wires, blue one side front, green the other and yellow the boot switch. Wire up as Mercedes/Audi vacuum pump with a 3 second delay (that depends on year which you haven't given. Diagrams here in relay section. There's also a total close wire on some early nineties variants. You can also pick them up in the front floor looms, in rubbery tubing along with a RED / white and a BROWN / black. If you start with "Hey Guys" again I will visit Oz and strangle you.

thanks

it is a merc 1989

i understand the wires you are talking about.

i have attached a picture, you can see the

2pin straight plug what wiring and or switching has to be connected to them

and also the 3 pin plug, looking at it from this angle which wire connects where

btw u are a life saver, and i wont say that again ahaha

sorry it wont let me upload it. are u able to send your email via pm or thru here

No point, you have the colours go from there.

i cant just hook it up. the wire are all burnt out

the wires have no isulation just copper

i need to re-run the wires but need to know what feeds and switching the pump needs and on what terminal

I've got no wiring diagrams which is what you will need. I can tell you that logically the other plug will be your RED / white fused 8 or 16 amps, engine bay fusebox marked central locking and brown to ground (earth). There's a dead short somewhere. Otherwise the fuse would have blown unless some idiot previously placed a much larger capacity fuse there.

take a look at this, it should be all you need 300CE wiring diagramThis information is provided only as a reference.

All circuits should be verified with a digital multi-meter prior to making any connections.

yer howie from the back story i think someone bypassed it at the fuse box, now its a bloody mess. burnt out need to re-wire

but shouldnt be to bad im not going to worry about the pump trigger wires, iv fitted an alarm with 3 sec pulse to trigger it.

thank you so much 91stt, that is perfect exactly what i needed

Common, I even got the colours right all from memory! Haven't done one of these in 20 years they changed everything about 92. The only mistake was thinking it might have been 8 amps. When I get my memory back I'll tell you about the total close wire.
