When I disassembled a 123, in addition to pulling the complete heater assembly, I pulled the wiring. Actually , as I remember it I pulled the underdash and engine compartment wires and cut off the wires leading to the rear part of the car. I haven't tried or had the need to wire another car with what I pulled out, but sections of the wiring and connectors have come in handy. There are companies selling reproduction wiring systems, but I haven't noticed one for a 123. You could Google it.To add to Barton's wiring question - I have considered replacing (i.e., rewiring) "some_most_all" of my almost 30 year old wiring. Anyone ever done such a thing?
brian from la verne, ca
Some new questions:
1). Is it possible to order replacement wiring harness components? i.e. like the set of wires going from the battery + terminal to the starter itself? Or is it better to bypass and wire with new, fabricated "patches" into the wiring harness?
2). Specifically, I also went through the glowplug harness connections. While all the terminals and glowplugs are shiny and new as they should be, the original harness is still in place and there may be exposed wires, the plastic coating is definitely cooked and most likely original. It looks like these five wires lead into a single plug on the left fender where the glow plug fuse is. Can I have this part of the wiring harness rebuilt, or can I buy it?
thx in advance, fingers crossed this was the problem and back to normal weirdness soon..
As above, thanks to all for your replies - and yes, I did try firmly shutting (but not slamming) all four doors, the trunk and the hood and all had zero effect once the car went "dead".
