2001 V70 Wiring Harness

Postby gchardy » 05 Jan 2011, 17:09

I am looking for an answer to what is the color code for the wires in the wiring harness at the rear hatch hinge point that are for the Spoiler brake light and the alarm system. (I need to return / repair and switch them around following a repair to those severed wires).

RaymanSean,
Thanks for the link.... I had to wait awhile for the PDF download.
Referenced the 2002 model (unable the 2001 PDF). Page 114 Wiring Harness 54-50.
The answer to my mixed up wires;
Trunk Lid Tail Gate Lock, P,Y & GR.
Auxiliary Brake Light, Y.
I see there are two yellow wires for differing circuits... should be a breeze to sort out - Easy to see how they got mixed up.
Thanks again, Graham.

Glad to see you found it. (I am always afraid when I point someone in the right direction [like I did above, because I do not know the answer] that they will interpret my response as being mean. Maybe it is because we can not see or hear the nonverbal cues when reading what someone else wrote.] Hope you get things sorted out.

Here I am a year later.. this time all twelve wires of the upper left hinge area are severed. I will be fabricating some kind of stiff conduit to stop the flexing in this area this time around. See you later, I have a few hours of soldering and fabricating ahead! Graham.

At this point I would cut all the flexing wires out and replace them in both directions about 2" beyond where I could secure them to non moving parts. Your wire is clearly work hardened and I would bet you will be here next year doing the same thing. Go to a local cable dealer that will sell you the proper smallest gauge wire in the bundle with a high strand count, buy at least 50' and some heat shrink and some labels. As long as the old wires continue to flex you are just putting band-aids on the problem.

You are correct Rayman about the stiff wires, Canadian winters are brutal on this harness and with the frequency the back hatch gets used by us it seemed inevitable that the wires were destined to a second round of severing - this time twelve wires were crushed or severed.
Great idea to splice in the extra length.... in fact I already had done so, on average about 5 inches extra. I would state that an additional six inches length should be considered a minimum to each of the twelve wires in this harness from connector 54-50 to the hatchback / door.
Secondly I went to a Hydraulic supply store (Princess Auto for you Canadians) and picked up two lengths of Hydraulic Hose Wrap called "hose wrap spiral" - two feet of.375 inch internal diameter and a foot or so of .5 inch internal diameter of this wrap (four bucks). The .375 wrap surrounds the wire bundle from the hatchback / door rubber grommet right up snug to the end at the 54-50 connecter that is fastened to the pillar roof support. The .5 wrap surrounds the wire bundle and the .375 wrap from the hatchback / door rubber grommet to a point inside the roof liner and I locked it in place there with a yellow zip tie. I will post pictures! I was going to control the movement of the wires with the opening and closing of the hatchback / door with some mini bungee cords but was very pleased in the way that the "hose wrap spiral" handled the job independently.
I think I have this wiring problem handled better than any Volvo engineer could do.... or was it a Ford engineer - say no more!

For those who have many of the wires severed, in my case, there were four yellow wires, two grey wires severed and was not sure which went where?! Sure you can spend a great deal of time perusing the 165 page wiring document for this 2001 Volvo V70 - there are at least eight separate wiring diagrams you have to wade through to get the following. If you are interested here it is in a nutshell - beats the trial and error method hands down too!

The 54-50 connector fastened to the door pillar post is a 14 pin connector - looking down the female plug-ins you have the following layout... top row from left to right is numbered 7 through 1; bottom row left to right,14 through 8.
====================================================================================================
Color code; top row: pin 7- black, pin 6-black, pin 5-yellow, pin 4-pink, pin 3-yellow, pin 2-grey, pin 1-lg. red.
bottom row; pin 14- lg. black, pin 13 and 12 empty slot, pin 11-grey, pin 10-yellow, pin 9-white, pin 8-yellow.
====================================================
Pin 1 = heated rear window - Large Red wire
Pin 2 = park light, tail light, license plate lighting - Grey wire
Pin 3 = brake light - Yellow wire
Pin 4 = alarm - Pink wire
Pin 5 = anti-theft - Yellow wire
Pin 6 = license plate lighting, central lock, brake light - Black wire
Pin 7 = rear window washer wiper - Black wire
Pin 8 = rear window washer wiper - Yellow wire
Pin 9 = rear window washer wiper - White wire
pin 10 = central lock - Yellow wire
pin 11 = license plate light, central lock - Grey wire
Pin 12 = empty slot
Pin 13 = empty slot
Pin 14 = heated rear window - lg. Black wire
======================================
I have to add that the wires coming from the hatchback / door can only be resolved by removing all the hatchback panels and utilizing a volt / ohm meter to ascertain the corresponding wires to match.... have a label maker standing by to remove any future doubts - leave the labels in place for next time.... you never know if you may have to revisit. I did!
Happy wiring!

Here are three pictures of the hydraulic hose reinforcement of the wiring harness utilizing "Hose Wrap Spiral" as detailed in two posts previous!
Wrap encompasses from hatchback / door rubber grommet to 54-50, a 14 pin connector at roof pillar post.
One picture of the hatchback / door open, the other closed.
Bullet Proof!
