The hazzard warning light in the diagram has a live on both side's. Is the drawing correct?

[whiterabbit]

The hazard warning light comes on when the indicators are off, in anti-phase as it were. It relies on the fact that the resistance of the small warning light bulb is much higher than the resistance of (4 x 21w + 2x 5w indicator bulbs all in parallel), so most of the 12 volts is dropped across the hazard bulb and very little across the indicator lamps so they appear to be off.

When the flasher relay cycles it 'shorts out' the hazard warning light so all the voltage appears across the indicators so they are on. This is why LED indicators won't operate the hazard lamp unless you put a 6 ohm resistor in parallel with each to increase the current in the circuit.

Here is the circuit for a Mini 2 speed wiper motor connected to a Sierra '87 - '89 switch and interval timer.

Here is the side and headlight circuit. Even this has some quirks. The sidelights are straightforward, the full current goes through the switch. The headlights have relays for both dip and beam. The switching is on the earth side of the relays, a relic of the heinously complex dip-dim circuit which we don't need. The advisability of daytime running lamps is a popular debate at present. Personally I put my side lights on at the slightest excuse, it seems an especially good idea in a small, low, fast car.

Whiterabbit wish I had these drawings when doing mine I just about went blind with the Haynes manual Glasses, bright lamp and hours upon hours but got there in end.

I just bought a complete loom from PREMIER WIRING which supplied every connector needed , heat shrink , etc plus typed instructions on what goes where -- colour coded etc -- job done.£150

The PREMIER WIRING loom I got was great for everything but... there it just too much of it!!

It is well thought out and contains all you need, though you may still need to source some connectors, instructions are good and the own of the business is very helpful - goes to all major kit car events.

The only problem I found was that for the Stylus there is just too much of it to hide behind the dash; there are separate looms for the engine bay and to the rear - these connect to the main loom (all included). The problem is there is making the main loom neat behind the dash.

I am not great on making things neat and tidy, just getting things working - but the loom is good and everything is working fine.

When I wire the R1ot I will be doing a DIY job on it as not windscreen wipers and wanting to keep things simple and minimalist.

Having seen a professional's wiring on a Stylus -- I would have to agree with you

A quick post-script, I have now competed all the wiring according to the above circuits, and it works ok. The 31 connection to ground on the head light switch is the 1/4" blade on the top of the switch on the left and should be plain brown wire. Why are there two connectors different from all rest? Search me guv! Just one of Henry's curved balls to upset kit builders.
