Last week I pulled the engine and transmission from my '73 XJ6. The head gasket failed last summer and I found a fully built up 4.5 litre XK engine with manual conversion and triple webers so I’m going to put that in.
But first - the wiring harnesses in my engine bay were a mess. Lots of splices, electrician tape, crimp connectors and a variety of wire colours. A lot of it came apart as I pulled the engine and disconnected everything.
I found a source for brand new S1 wiring harnesses and I’ve identified the following:
- passenger side engine bay harness
- driver’s side engine bay harness
- firewall harness that runs laterally
My question is this: Before I start pulling the interior apart, where does the passenger side (large) harness connect to inside the car? Where does the driver side and lateral harnesses go? Ideally I would replace all three of these but leave as much of the interior and dashboard harness intact as possible.
Lastly: Does anyone know a source for the unique Series 1 firewall insulation? It appears to be thin aluminum over foam that is glued to the bulkhead. I traced mine before I peeled and scrubbed it off so I can replicate it, but I haven’t seen that style on any other car or in any catalogue.
Below are some photos of the old engine coming out and the new one that will be going in.
