Rewiring

Hello
I'm in the uk and a friend who does not use the Internet has asked me to help him rewire his 1942 gpa. He has a new wiring harness but has no idea of the route front to back which the harness takes. There is Currently no existing wiring on the vehicle. I have browsed the site and found some brief descriptions but cannot view the accompanying images (they state not viewable in my region). Currently I haven't yet seen the vehicle, will it be obvious which way the harness needs to run? Is there a source for a good wiring diagram? Many thanks in advance

Hi iain,
GPA manuals are everywhere for sale.
If you order my GPA book, there is all the info and wiring diagrams you need. (35,- euro, plus postcosts)
There is a difference in early and late wiring !
Early wiring is through the chassis beam, and late wiring through the side coam.
In Australia the correct replica wiring is for sale.
