TR2/3/3A Wiring harness

I am looking at ordering a replacement wiring harness from Autosparks in the UK. I am planning on having them add a circuit for an electric fan. They also offer wiring for an alternator. I am converting to mini denso unit but am not sure if I want it prewired for the conversion in the chance I ever decide to go back to a generator. I was curious if anyone had ordered a harness with the modifications and what they thought?

If Autosparkes hasn't change their policies you will not be able to order direct. They will forward your contact information to British Wiring here in the USA. However, if you can locate a Triumph distributor like Rimmer Bros ect. in the UK you can save a few bucks by ordering through one of their Autosparks Distributors.. I have many changes to my harness which Autosparks did for me including a single cable for Denzo Alt. AH Spares handle the order for me. It was a bit difficult because I had relays but, when it did arrive it fit great and was able to get everything in working order.

I've used Autosparks harnesses and they are very good, and I've also done a Denso as well as Delco conversion but not incorporated it into the wiring harness. For what you need to do, if it were mine I'd just stick with stock as the connections are pretty simple - the Denso alternator I used needed a switched power source, which was a single line I ran from the fuse box and really not very noticeable. The other connections can be discreetly bundled together at the control box (gutted and used as a junction box). That gives you ability to go back to stock and really nothing looks unusual when you put in the Alternator.

Update, I was able to order directly from Autosparks and ship to the US. The harness is factory with the addition of wires for an electric fan. With shipping it was still $90 cheaper than ordering from US suppliers.
