Just some update for those interested.
My original A/S harness was for a 1970 era trans. This trans has two ATF temp sensors, and the temp sensor selector fitting on the trans housing. That harness was partially burnt crispy and most of the insulation (outer cover) over the wire bundles was hardened from excessive temps and age. Unusable, but 90% complete. This is a 1970 convertible Ghia I'm restoring.
My replacement trans is a later model, one ATF temp sensor.
I dissected the original harness, measured everything and rebuilt a new harness configured for my replacement trans - nearly bone stock. I had to salvage one of the three prong white terminal connectors for the starter cutout switch, and the L-shaped rubber boot for the ATF temp sensor, cause as yet I haven't found a suitable aftermarket supplier. Otherwise all the wiring is proper size and color, all the terminals are as stock.
I first blueprinted (created a wiring diagram) of the original harness, then created another diagram for my current trans. I did wiring take-offs for the original, then used the necessary info to create take-offs for my harness. I am in the process of finishing out the insulation and documenting the material requirements for that as I go. At the end of this process I think I would have enough info to fabricate any year AS trans harness. Now I have to figures out a way to get all this info out to you folks.
Awesome man, When you do get all of the info together please send me a copy. I bought a harness for a manual and the wires that went to my A/S trans were pretty much useless also.
Hiya Larry,
Nice work.
Reproducing a wiring harness on your own sounds like very intensive labor to me. Kudos to you! I have a feeling you'll be fielding electrical-type questions here in the future! Looking forward to your updates and information.
All,
I tell you, the actual work of assembling the harness is perhaps 1~2 hrs. for a novice, not more. For someone who has had a little practice I bet it could be done in minutes - it is that simple. This is not a complicated harness.
Blueprinting the thing in the first place - that was the real work. My current sketches are hand drawn and legible (I'm an engineer by training) but don't have the material list compiled yet. I will update and post up here when I do. You have to know that even with a material list and a pile of pre-measured 'parts', assembly would require some instructions - it is not as straightforward as you might think, but it do-able by the average hobbyist.
More later.
Hi
do you mean only the autostick wiring harness?
Lee
Lee,
Yes. It has connections for the starter cutout switch, the ATF temperature sensor selector (on early models) and the ATF sensor(s), and the reverse light switch. The harness runs through engine compartment fire wall and has a connection for the control valve at then the backup lights. At the other end it runs through the frame in penetrations just off the frame tunnel. Here you have leads for the ATF temp sensor light on the speedo, the starter wire from the ignition switch and the contact on the stick shift.
yes, that will be handy for someone...
as many people like to replace the old wiring...
and I agree that drawing the diagram etc is time consuming
I did draw a bit of a diagram once for someone...
and the finished job looked terrible...
although it could be read... lol...
I did all My car about 10 years ago..
and i'm still having little problems now and then
as I didn't really follow the VW wiring 100%.
I used seperate wires for everything
plus some spares..
plus i didn't label many of the wires
which isn't good when you have 50 wires
colored - red- blue- green- grey- black- white-dark green-dark blue-
cheers

Hi Achilles im also putting a later trans in my vert but only have a burnt out early loom so any info on the later loom would be most welcome
thanks phil ;D
All,
Apologies for not posting these up sooner but I am engrossed in this Ghia project thoroughly and it is really taxing my skills.
Attached find two simple sketches - use with CAUTION; these are not nearly as complete as I would like but I wanted to get something posted up. The first is a basic wiring diagram of an early Autostick harness, the type with two temp sensors and the temp sensor selector. I have tried to indicate wiring colors and sizes, locations of insulation and insulation sizes (diameters) and wire lengths. If you laid such a harness out on a work table, it would appear roughly as shown in this diagram. This is the harness that came with my '70 Ghia originally.
The second sketch, based upon the first, is for my car as rebuilt, which now has a later model trans which has a single temp sensor.
I think if you know what trans you are using, you could use these as a starting point. I fabbed my new harness using the second sketch and it turned out remarkably well. Couple these diagrams with the Bentley manuals colored wiring diagrams and you should be in good shape.
My intent, once I get my car rolling, is to pull out my original harness (still have it), check all the dimensions including 'leadouts', insulation, etc. and CAD the sketch with a Bill of Material. Something you could actually buy/build from. Don't hold your breath waiting for that, though.
Thanks for the info Achilles
I'm sure they will be very useful when we get a chance to start on the wiring for the vert
luckily my daughters boy friend is a wiz kid at automotive wiring ;)
Ive got bogged down with engine building at the moment and i still need to renew the clutch in the late box
I hope you wont mind me picking your brains when we get to the wiring stage we may need help ;D
Thanks again all the best phil
There seems to be an issue with the file attachments here. Can they be fixed? I'm doing a restore, and I plan to replace all the wiring. I would like to do my own AS harness to fit in with a normal VW harness. The diagram seems like it would be very helpful.
Thanks!!
Travis
The .jpg files seem to be corrupted. Can anyone repost them?
Thanks
