Multiple ground runs and supply will be part of the FMEA results for safety etc, this is also why certain modules will have two power supply pins and the like.  :y

Its also done to reduce EMC issues

Sorted a lot out, shortened down some of the runs . Made the centre locking / window wiring into a separate loom , electric mirror and speaker  wires still to sort out/remove.
My next mission is to make a box for ECU or see if wires will go through bulkhead so ECU can be fitted inside, its all a bit tight( ooh matron)  but have to fit heater fan first.

Why did Vauxhall/Opal use an odd as wheel stud size, sent me on a merry chase trying to find some 4.5 x 15 rims. Ended up getting some Weller smooth centres of the bay , NOS? custom made with Jag 4.75 in x 5 PCD so will have to get front hubs redrilled --------Good job I know a man that can.

Why do you think it's odd?


5x110 PCD isn't uncommon


and the M12x1.5 studs are European standard.

There isn't a lot of space under a '50s Austin.


Another thing to remember is that old cars don't weigh very much, and wide tyres on light cars make for a horrible drive: you seem to have lots of grip, until suddenly there is none. And that's in the dry.

Ian's MGB is on stock 5x14 wheels with 185/70 Avons....

Fair enough, it's easy to forget that wide wheels were once a novelty rather than the norm...

185/195 were considered to be the wider end of the spectrum for normal cars. Now 225 is pretty much the standard.

To keep the ABS happy running 165 x15 front and 235/45 / 17s on rear on Saab rims. Have found some Weller smooth centre rims for front (NOS custom made!!) but Jag stud pattern 4.75 in PCD so looks like hubs will get machined.

Why not modify the wheels? Fit the centres that match your suspension to the barrels that match the car.


Your mix of old and new wheel/tyre sizes is going to look very peculiar, have you considered using a 15 or 16" tyre on the back with a similar rolling radius to the 235/45 17? The stock Omega tyre sizes in those diameters would be a good start.

The A40 Countryman from the early 50s was my first car. It was OK until the crankshaft broke :'(

Well its coming along slowly, still doing body work. Had to alter the master/servo cylinder fitting angle to get clutch pedal to clear bulkhead with room for carpet and then rework the Omega pedals for angle. Needed some insulated mountings for the heater fan and in my box of wonders discovered a exhaust? bracket with GM on the rubbers, it might have come off the Omega. So a cut and weld and 2 bits of off cut bolt threaded sections welded to under dash cross brace works well.
