Wiring Loom - how hard to do

Discussion in 'Mech Tech' started by salad.dodger2, Sep 23, 2015.

  1. Hi guys. So I want to attack the old look in the Devon.

    If I buy a new one, how hard is it to do and how long does it take?

    Do I need to take the engine or fuel tank out?

    Hate, hate electrics!!!

    Thanks :)
     
  2. me too ,but found it quite easy ..

    I cheated with the fuel sender...;)

    dash fuse box and igniton is the hardest..

    just take it steady ...:hattip:

    could be worse I had a few burnt looms in cars to replace...(nightmare)

    take pictures...;)
     
  3. Cheers dude.

    What do you mean you cheated with the sender? mine no worky anyway :confused:

    Did it take long ?
     
  4. Its easy enough to do, take lots of pics and make notes of what goes where - you don't need to take your engine and fuel tank out

    If you reach up where the wire disappears to the fuel sender, you should be able to pull it down enough to expose the connector, you can then disconnect it from the main loom. If you can pull it through, you should be able to reach it through the paint tin lid hole where your filer pipe is.

    disconnect every thing from the cab end (after taking pics and notes) pull it through to below the cab. tie some string to the disconnected end and pull the loom through towards the rear of the van from the other end of the conduit. Disconnect everything from the engine bay and pull that back to the starter motor area where the rest of the loom you pulled through is. Obviously you will also need to disconnect from the starter also

    .....and before you start make sure you disconnect the battery :D

    taking old one out and fitting new one should take anywhere from a couple of hours to half a day

    factor in a week for fault finding when things don't work because you've lost your pics and note book :lol:

    get your self a colour wiring diagram before you start :thumbsup:

    are you doing the cab loom as well? if so, do the main loom first connect everything back up and check every thing works, then do the cab loom. That way you will reduce what you need to fault find if things go wrong :)

  5. New loom is about £200 to £250-ish , think they`re called custom looms - dunno if this is an option but when the time comes i`ll be hunting `em down ...

    A fellow hater of elecrikery :thumbsup:

    :hattip:

  6. Only problem I found when thinking about it was getting the right coloured wires??
     
  7. The loom had a wire that came off for the sender, but found the original so just crimped it...

    Took about 8 hours, but the one I changed All light wires etc were yellow..

    The multimeter was essential...:thumbsup:

  8. I also used to hate electricity - I now love a bit of electric fault finding!! Just get a 1/2 decent multimeter (mine was less than £20) and be methodical. You only really need to be able to test voltage, resistance (for fuel senders etc) and continuity (either by testing resistance or with a beep if your meter has the function). Occasionally you may need to check current draw, but I've only ever done this to check why batteries were going flat. There is a write-up on here somewhere on how to use a multimeter which is useful...

  10. There is a cab loom? I thought it was one loom?

    When I googled I'm sure I only spotted 'a loom' for T2 Bay.

    Good reply though, thank you very much dude, and for the links above :)

    Gonna be interesting but focusing on the end result :thumbsup:
     
  11. Hmm that too. Also need to replace the bulb holders for the dash.

    Those are really bad in mine. I was driving it, but electrics started getting crap so pulled it off road. :(
     
  12. yep, there is a cab loom, they are 2 separate pieces joined with the connector by the fuse box

    If your buying one, check if it is just the main loom or both

    Will be worth checking they are to the original colours, some of the aftermarket ones arnt, which might make future fault finding a little more tricky against the VW wiring diagrams

  13. forgot to mention, before you pull the old loom out you will need to take the plug off the end.

    insert a small screw driver in to the front of the plug to release the tabs on the crimps, and then pull the wire out of the back of the plug
