I'm just sorting out my wiring using a Sierra Steering column and escort MKII Loom. I got the lights sorted out over the weekend now about to start the Indicators and Haz lights.

The sierra has the haz switch on top of the steering colum - a red pop up switch thats lights up when the haz's are on. First Question is this switch live with the iginition off ?

I need to connect this to the escort MKII loom. Has anyone done this if so any chance of a guide. It would appear that the escort uses a different type of switch.

Any help appreciated

Cheers Chris

Chris,

Surely the hazard switch has to be live with the ignition off as you have to be able to have hazards on without the ignition eg when you break down or run out of petrol, have to walk to find a telephone box/petrol station (in the days before mobiles) and need to lock your car.?! (IMHO of course)

Yep thats the assumption - but the Sierra was dead when I took the column out and I read somewhere that some sone of the Sierra ones aren't. So I thought I'd ask.

The escort has a switch with about 6 wires going to it thats located on the dash. The sierra is all in the column - indicators on a stalk and haz on top.

I would have assumed also that it would have been an SVA equivalent/MOT necessity on new cars at the time - what age was the sierra?

I know my first car - a 1974 triumph toledo was pre-hazards! (ie had none)
My Dad had a '77 Dolly sprint and that had hazards, presumably they were introduced mid seventies - surely someone out there has something to add to our congesture.....

the hazzars have to work without the key in,easiest to get the plug from the back of a seirra switch,and look in the good old haynes manual for wiring conexions,btw wiring colours changed between mk11 and seirra,ive probly got a plug laying around if u want it

I kept the plug off the sierra and think Ive got all the wires in the correct place. On the male bit of the connector left on the column it has the numbers 36g etc which seem to tally up with the ones from the MKII haynes manual. I have not got a sierra wiring diagrame to see how the the haz flasher wires in.

What got me head scratching was the escort loom. The connector block for the MKII Haz switch has about 6 wires going into it, cant remember the colours other than a red a black and a black and yellow and a few more. Its where to put these wires that was confusing me.

Thats not to say that with a fresh mind tonight it wont all make sense - it did nt yesterday tho

Assuming I can find my usb cable I have a sierra haynes manual at home and can take a picture of the relevant circuit if you like.....

yes please

Don't forget that a mkII has the hazzard warning light on the dashboard , and the sierra switch is itself the warning light !!! - that may explain the different number of wires.
phil.......

ok, haven't found the usb cable but have the haynes manual in front of me at work.

What year is your delightful sierra column from as according to the manual there are different looms for:
upto '87
87-89
90 onwards
p100 models 88 onwards

Andrew.

I presume its pre 87 - I had a glance through the haynes manual at Halfords this lunchtime (someone else had already taken the clingfilm off!). What I could do with is a copy or drawing of the column switch - with the terminal numbers etc. Its number 102 in the wiring diagram.From the glance I had I dont think it will be easy to wire it up to the MKII loom as the sierra uses relays and the MKII doesnt. I am hoping I can just suss it out to plug the MKII wires into the switchgear and use the Haz switch on top of the column

Have a look in the dipped headlight thread lower down the page. I drew my switch out as I wired it for Northy, it may help. I used the Sierra switches but made the loom up as I went along. The hazard has its own live as it has to work with no ignition. Also the same switchgear is used on one of the fiestas(MK3 I think) and it is available with a horn push on the indicator stalk or the steering wheel.
