s type 1965 strange wiring problems .. help
#21
Rewiring would be a big job but I don't think it would be particuarlly difficult with the car assembled, you would need to take out the seats and dash and some trim panels to do it properly but otherwise it would be fairly simple just time consuming.
When pulling the looms out of the sill tie a wire/rope to the end and middle so you can use them to pull the new section back in.
Personally I would try and fix what you have unless its in a really bad way.

You would also have to take sections of the carpeting/underfelt out. It's a pretty nasty job depending on how much time you are prepared to devote. The rewiring took us a long while even with just a painted body shell inside & out. People who have not rewired an S Type are likely to see it as easier than reality. Things don't just pull through as one would wish. They bind & fight you in many areas if you don't want to damage the harness. e.g. finding the B Pillar connectors in the side harnesses that are in a blind 3 part sill. Things like twin fuel pumps complicate issues etc. It's not a Mk2 with 2 part sills etc..
I would fix what you have with the help of an Auto Electrician if necessary.
When I see the rustbucket Mk2 that Homer brought back to the living I'm truly impressed. I would have sent it to the crushers. At least I had a totally rust free shell/car. If Homer costed in his time I hate to think what the cost would have been. His idea of difficult/time consuming & other's would likely vary/differ.
I salute him for saving a car!

The Majority of S Type Harnesses, Numerous minor bits missing. e.g. horn wiring.
Column Harness ~ MOD. Auto more complex
Similar to S Type, Connects to dash harness pigtail that runs under passenger carpet & pops through O ring in tunnel.
S Type version wired & terminated for new OD inhibitor & Reverse light switches. Long lead goes to OD solenoid.
Excludes interior rear centre light harness
Centre Panel Harness.

At present, my Mk2 has both outer sills cut off. It still looks pretty difficult to thread a harness that goes both up the B-posts and through to the back of the car. If I were to re-wire, I'd be tempted to abandon the route through the sills and make a conduit along the floor inside the car.

Fortunately the wiring in my S type is unmolested and intact. Any new wiring has been done by me very very carefully and without accidents. New stereo with 4 speakers, spot lights, emergency flasher, electric door mirrors, center mount stop lamp. All done by yours truly. Hey if it's one hot and 1 ground, I can do it. No digital anything thanks.

Jose, Glyn, I'm certainly not planning on any re-wiring. Everything (apart from the clock) worked when I took it apart and the harness looks OK. I will run some extra cables through to the back of the car in case I think of a useful accessory or modif later.
Don't ask me about the quality of the original construction of the bodies. I've read that at least once in the 1960s Jaguar sent a large number back to the Pressed Steel Company because of poor quality. Measurements with a water level gauge indicate that my MK2 should have been one of them. All the 'chassis' and suspension points are level to within 1mm. However, the left side rear wheel arch and the adjacent door post are 4 to 5mm high. Looking at the welded joints inside the car to the rear of the back door, it's clear it was put together like that: flanged edges bent down to meet and others badly aligned. I've joked about taking it back down the road to the old Pressed Steel factory, but I don't expect BMW-Mini would honour any warranty.

The trick is to get some good stout single core building electrical cable or something similar, pus that through the sill and then tie or tape the loom to it and put it out pulling the new loom in. Doing this method the LH side loom took me e around 30 minutes on my current mk2 project.
I fully appreciate that it was the first S Type I'd rewired & was learning all the way, but when I look at what you have done I think you have far more patience than I do. My experience lies in different areas. You would not want me to weld something for you. My restorer/helper is a genius at metal fabrication. He will build you anything well & accurately & makes working on an English Wheel look like child's play. He does a perfect job of any kind of welding & has all the kit.
I don't know the OP's skill set but I think he might curse trying to rewire his assembled car. I think he should diagnose & fix what he has, probably starting with the last thing he touched prior to the problem occurring.

Yes but you have a Mk2 with 2 piece sills. The S Type has 3 piece sills to stiffen the car. How did you capture the B post connectors? Peter is installing 3 piece sills of his own design

I didn't do this on my S Type so I had to start from scratch and just used a draw wire fished through, I don't remember it being difficult.
Fully agree the OP should avoid rewiring unless absolutely necessary and even if it was it doesn't mean the sill looms have to be changed as their issue will be with the main loom.

None of this explains how one easily catches the connectors to the sub harnesses that go up the B pillars on an S Type. In Peters case the pre welding on the sill trick would work with the possibility of damaging the harness but not with an assembled car.
Anyway I think we have discussed this enough. Possibly easy for some, less so for others. Like most things in life dependent on experience, skill set & time.

I've never done it and hope I'll not need to, but I understand that the trick is to have a separate draw string for each branch of the harness. And each draw string has to be labelled (for example by tight knots) at each end. There would be one string for the branch that goes up the B-post and another for the one that goes all the way along the sill. Then, with suitably judicious and simultaneous string pulling, a new harness can be installed. Of course, you still have to find a way past all the invisible obstructions.
The advice that Geoff Maycock used to give was to wrap with tape any part of the harness that you had access to if it looked at all warn or looked as though it might suffer in the future. That way most re-wiring can be avoided.
