My two sons and I have three 1990 Jaguar XJ6's we are making one nice one from the three. The main one we are using had caught on fire burning the drivers side under the stearing column quite severely. Also on the firewall on the drivers side in the engine compartment slightly. We have the dash and everything removed from the car. We have a hayes manual that is not much help to me so far, I oredered a windows based service manual from e-bay hopefully that will help us more. The main thing we are needing to know is can the wiring be split somewhere in the middle of the car without actually cutting and splicing wires. Im trying to keep the splicing to a minimum. There are many junctions or plugs. Any suggestions would be greatly appreciated. I'm suffering from actual wiring nightmares!! (Im serious)! Thank you all very much, Patrick and my sons Patrick Jr. and Jesse.

 

We recieved our Factory Service Manual today it looks very promising. Very good illustrations of all wiring. Looks like the way to do it proper is to replace from tail lights to headlights (the whole harness)!! Was hoping to not do the whole car?

 

Better off doing the whole car and knowing it is correct than leaving some old wiring to cause another fire!

 

If you go back with a factory wiring harness, you'll still have a Jaguar wiring.
This is your chance to have a clean slate.

Have you heard about Isis modular wiring systems? SpeedTV used Isis when they built Factory Five's new 33 Ford hot rod with a new Ford 302 Coyote crate engine.
The system is discussed in: ISIS 3-Cell Starter Kit - Kit Car Wiring Harness, Car Wire Harness, Automotive Wiring Harness, Auto Wiring Harness, Auto Wire Harness, Car Wiring Kits, Automobile Wiring Harness, Ignition Wiring, Car Electrical Harness. They claim that a complete auto wiring installation is a 20 hour job--vs. a 40 hr. job conventionally. Troubleshooting is also a snap with Isis.
