One of the wonderful things about TVR is their attitude to wiring. I had half a dozen or so loose wires behind my dashboard. On querying this with TVR staff I was told it was normal.
It means that all wiring for TVRs requires both guesswork and inspiration. There are diagrams of switches and instruments. There’s a full wiring diagram of, what I am told is, an early Griffith. It seems it must be close as one TVR dealer printed it out and gave it to their mechanics.
There are a few Range Rover wiring diagrams. I used them to practice with the software, and it seemed silly to waste them. There is a lot of common ground between the EFI Range Rover wiring and that of the TVR.
Remember that it is guidance only. This is my best guess. That’s why it is free.
Just go to the buying page. There is no charge so don’t get hung up on the buying bit.
Please feel free to let me know you opinion on the book, remembering the price you paid of course. If you have any information, and, preferably images of wiring, please let me know via the Contact page.
