New Project Update 9th January 2003
I have been working on the wiring. This is in 2 parts. There is a loom
for the general car electrics such as lights, horn, fan etc and one for
the engine management system. I originally intended to get a loom made for
the engine management but the quote of around £800 was too much. I
want the loom to be 100% reliable so it will have crimped connections and
be sealed to IP67. A good crimped connection is better than a soldered connection
but a poor crimped one isn`t. Unfortunately I can not get a crimped connection
to the standard required with reasonable priced tools.
So I now intend to make my own engine management loom but just get the connections crimped. More on the design and manufacture of this next time.
The main work this time has been on the general car electrics. I planned each particular circuit and worked out the wire runs so I new what length of wire was required. I could then order the correct length of wire in many different colours. I also planned the position of items such as switches, fuses and relays to minimise wire length and to keep weight low.

are the ECU (not shown but would be on the left),
These are all the plans for the wiring. On each one is a small
wiring diagram wire lengths, sizes
All the general car wiring is done with a traditional soldering iron heated on a blow torch.
To identify each wire I bought a book of stick on figures.
These are stuck to the wire and

wire is first crimped
You can see here finished connectors. Heat shrink (non adhesive)
is also used

and an LCD underneath.

There are also a few warning lights for legal requirements.
