OK so my top does not go down and my door locks do not work from the switch on the dash. I went in the trunk to look at the vacuum pump and there are 2 wires that are not connected. A red one and a gray and red one coming from the pump area. I do not see a place to connect these wires to. They have a connector on the end but I do not see a place where they go. Can someone help me? Is this why the vacuum pump is not working? Help please Crossfires are new to me so don't know all that much about them yet. Thank You

 

Look in service manual on 8W-39-2 an 8W-65-2. Red usually means hot (power). There is a manual on your model available for download(bought mine, need paper I guess). Sorry not much help. I can't find a pairing of RD/RD-GY.

 

I have a spare pump with the four plugs and there are 19 wires that go to the pump.
One long black plug (C2) has 4 wires one of which is a large red/green wire, another square black plug (C4) has 3 wires one of which is grey/red, a white plug with a grey latch (C1) has 5 wires and a rectangular black plug (C3) with a gray latch has 7 wires one of which is red/gray and another brown/red.
They are the only four wires with red in them. The first color is the major wire insulation color and the second color is the stripe on the insulation.

Mine is a coupe harness I think.

The wires you have on the '05 circuits does have a a brown/blue and it goes to the lift gate lock switch. 8W-61-3.
Is that a roadster wire or not??????
I cannot find a red.

The wire colors are known to be different in some cases on the car, differing from the Repair Manuals

 

Sorry the wire colors are red with a white stripe and brown with a blue stripe. I still do not see a place to plug them in back there.

 

Are they just wires together with a connector on the end? If yes, the closest I can come is, Air Pump Relay Output,and even that is not the combination you described, they are RD/WT and Br. Look at a service manual in section 8w-80-2 it shows every connection on your car, wire pairings,an color codes, also the color of the connector itself. This is as close as I can get you. Hope this gets you to, what your looking for.

 

Can someone please look in the trunk of you roadster pick up the carpet and look and see where these 2 wires go? They are wrapped in black tape and go to a black connector. They are at the rear part of the vacuum pump.

 

A photo would go a long way helping solve this problem.

 

OK Tomorrow I will do my best to post a picture.

 

This is the mistery wire from the vacuum pump in the trunk

 

Back off a bit with your camera so we can see the area and the plug type.

 

I thought I needed stronger glasses, but then I saw the background was in focus.
Come on, you can do better than that.

 

Would that perhaps be the wiring to the tow away sensor mounted to the frame just to the rear of the locking pump ?

 

How hard is this for you crossfire experts? This wire comes out of the vacuum pump harness area inside the foam. It is not all that long but I do not see a place to plug it in to anything. I will take another picture but take a look inside your trunk of your roadsters just lift up your carpet. Come on people do me a favor i do not know much about these cars only had this car a week.

 

Did you check the tow away sensor ?

 

It is quite tricky actually, we have had the wrong color wires given to us, and a blurry picture of a plug with wires that could go any where. We do not all have roadsters so we have to go by what we have on our cars and the wiring diagrams.
I see this going to lights, hydraulic pump for the roof, or a switch that says the roof can move. I do not think it goes to the vacuum/security pump. You could try seeing what if reaches, maybe it is an added feature by someone but the striped wire makes that seem unlikely.

 

I figured it out. The wires go to the trunk light which is just sitting in the trunk. The back carpet part of my trunk is missing so I guess the light goes in that area. So now I have to figure out why my vacuum pump is not working. Can I ask what powers the vacuum pump in the car? Is this a common problem? If so what is the usual fix for the vacuum pump not working issue.

 

Try fuses #25 and #26.
If the pump does not work then it may have been damaged by water and this damage should be visible. Replacement is then required.
