Bird on a wire - the rewire begins

[magpies]

To start with I intend to use as much of the original wiring as possible. I'm using CBS module relay and fuse boxes and adding extra fuses and relays. Also checking the existing terminals and rete ruminating where necessary. This is also being done on a tightish budget. I am open to suggestions so fire away, I may or may not use your input.

The car has never had a steering wheel horn push,used a dash mounted switch. Is there a way of converting? I've seen rally and race cars with long curly leads but they look a bit messy for a road car unless it can be hidden. After inspecting the column switch plug connectors I found some signs of overheated plastic so I've dismantled and individually connected the wires. The female bullet connectors are an odd size.

Previous owner obviously had problems with the wiper motor connections and individually wired but I have just purchased the correct connector block and awaiting delivery.

How much unnecessary wire have you found so far Mick? Found any with colours that do not even appear on the diagram? I suspect they may have done better custom looms on later cars but ours appear to have loads of unnecessary wire. Incidentally, when you do your dash make sure you can get at the bulbs for the dials, couple are a ***** on mine. Your wiper is cable isnt it? A later car than mine. On the early cars the wiper cranks can cut through some of the wires very nicely!!

Redundant wires up to now

New home for the battery. Passenger footwell. Will make for short power cables and better weight distribution.


Not sure why the photos are not the correct way up.
And yes it is the (almost new) battery out of the Jaguar

You won't be needing a wiper relay or blower motor relay





https://en.wikipedia.org/wiki/Fuse_(automotive)#Bl...

You should be using standard blade fuses wherever possible apart from the maxi type as a safety fuse when picking up a supply from the master switch to wherever (not got to that stage yet)

Does anything need to stay as standard?

Nope - there isn't much standard left

Is this because the original switches are made for the load - which they are as they don't normally have relays, but I had been looking to reduce the electrical load on the switches including the Ignition switch.

The CBS fuse box choice is only either Maxi or Mini fuses - so I have chosen with respect to expected max loads. I think I have it ok.

Nah, you aren't trying hard enough!!! Like you I think the battery is probably better mounted vertically!!!

Ok, If you want to relay the wiper motor you will need to carry out a custom wiring job for the circuit and need at least 2 or 3 relays to get it working

The blower motor will need 2 x relays if it's a 2 speed

Why are you using an incorrect fusebox?
What is a CBS Fusebox? Do you mean a fusebox supplied by Car Builder Solutions?

I don't mind not using relays where not needed. Blower motor is 4 speed and doesn't really need a relay. Wiper again does not use a relay in the original wiring. Yes the fuse box is Car Builder Solutions.

Ok magpies. Have you already done your money with Car Builder Solutions? If you haven't, don't

yes but I have a good relationship with them so can deal with them with info.

This type of box will help you make a better job of it https://www.carbuildersolutions.com/uk/12-way-blad...

These relay holders are very good and cheap https://www.ebay.co.uk/itm/6-Way-Automotive-Relay-...

• ***Maxi Fuses***** You would be making a mistake in choosing this type of fuse for wipers and blower motor

These fuses start at 20 Amp and increase by 10 Amp's at a time, 20A 30A 40A and so on, the wiper and blower circuits may well need to be fused at 15 Amps and you would also come up against more problems if needing 25A fuses

As for the mini type blade fuses......they are horrible to work with and don't save much space

You may wish to have a rethink

Horn push should be on the left hand (indicator) stalk ?
