Hey all, Getting ready to send off my fuel rail and injectors to refurbish on the 90 and figured i'd replace the harness " while im at it" Was looking to see if anyone on here is making these for resale before I bought all the components to do it myself. Please message me with cost and turn around time if you do.
thanks
Started looking at parts today and I'm about $200 for wire, angled connectors from fuel tech and high temp loom. Not sure if I'll change the main connector yet as I really don't see the NEED for a weather tight one, these work fine for what they do. Will leave a little extra length in case I have a change of heart later on. Spoke with SNG, they are 12 weeks out on them so I can't wait that long. Can save another $30 if you get the generic EV1 straight connector off Amazon but I was told they need shaving to fit properly.
Is it possible to just.get.plugs...? a savings thing.... Then, build the rest of the harness yourself...?
You can buy everything except the big white rubber socket, that I believe requires a specific machine. Some people remove that bit and buy two 6-prong sockets and just rewire the end connection bit going back to the car.

Understood! Thank you...
I better learn to start thinking MORE outside the box...
I went this route following the diagram, but also used a piece of plywood covered with poster board,. Then I mounted my old harness striped of the insulation (or what was left) and used it
as a pattern.
A couple of the pink/black wires can be eliminated, if desired. You don't really need all four.
High grade, high temp wire is readily available (I forget the alpha designation at the moment) and not horribly expensive so there's no strong reason not to use it. But, in all honesty, I think the most important improvement in durability comes from re-routing the harness so that elevated away from the engine. Jaguar anchored the harness right onto the engine, ensuring that the harness is well baked. If, for whatever reason, a person wanted to use standard grade automotive wire, he could probably get away with it if the harness was re-routed.
There's almost no end to the variety of heat-shield wraps and tapes available. It's truly a 'tyranny of choice' situation. On my latest harness I used something like this and then wrapped the whole shebang with Tesa black tape (Note: Tesa makes a variety of tapes, not all are rated for high heat, so be careful)
You can buy pre-made injector connectors with 'pigtails' for $2.00-$10.00 each. I've had no problems with the less expensive offerings....and found out that, in some cases, the more expensive offerings were the exact same part but merely higher prices! Just Google "Bosch Injector Connector"
If you can live without the 2" long rubber boot at the injector connector you can save money, as I've never found those for less than about $6.00 each.....adding $72.00 to the project! I use a couple layers of shrink tubing instead
Guys- just a quick note. We have a supplier that can make pretty much any of the XJS harnesses including the Marelli ignition harness. All of the harnesses are made with modern wire, new connectors, etc.,. He makes all of the special harnesses we use for the XJ6 and XJS engine conversions and has for years. All of those plug into the chassis just like the originals. He has the capability to mold the rubber-ish connectors that Jaguar used on nearly all of its wiring until the early 90's,.... BTW, he also has harness braiding capability as well so the original style fabric covering is available if wanted/needed.
Just as an aside, he also does rework and has completed several full 92 engine harness rebuilds for a our customers. In case you weren't aware Jaguar used a terrible quality wire in the 92 harnesses, so bad in fact that the wiring just fell apart (insulation turned to dust) leaving nothing to even repair. He took the remnants and reworked the entire unit, just like original which then plugged right back into the car... And of course the modern wire and components should last forever essentially... Attached is a pic of the last 92 harness he did, all strung up on the board as he works, and a close up of the finished product.
Our guy has been doing this for years- if you need something, send me a PM and I would be happy to look into it.
