Mk2 dash wiring

[swedge]

Gonne be fitting my mk2 dash today that I received from colin (cheers)

I noticed a black wire quite thick attached behind the dash round about where the ciggarette lighter is, I can get a pic later on of it

anyone know what it is? Also my mo1 dash never had a cig lighter or clock so will the wires be there for them already just taped up or would I have to wire them in

cheers

Just run fresh wiring, its easier than bodging about looking for the right wires that may not even be there.

Where's the easiest place to take the feeds from? Are the both permanent lives for the cig lighter and clock?

This is the black wire I don't know what's for.

Looks like a homemade earth, where is the other end?

[swedge]

Dosnt go anywhere just a bare end

[bazil]

If that end in the pic is onto that screw then bit it, it's not factory and IMO an earth done poorly.

[swedge]

Yeah it just goes to a screw

I've just took out my mk1 dash and found a toggle swithch behind the glove box that's stickered alarm lol dosnt connect to anything though

On the mk2 headlight swith there's a black wire but no black on my mk1 loom

Any ideas?

This one looks harder than it is. The Mk1 connector has 3 pins, whilst the Mk2 has 4 pins. However, the Mk2 has a looped connector on pin 4 (to pin 3) - follow the Mk2 loom up from the switch and you will see the looped connection. Ignore this loop and leave it as is, connect the grey/green wire that goes off into the loom to the yellow wire on the Mk1 loom.

I can't see any yellow wire to connect the greY/green wire to do I just join the grey/green and grey/yellow together then to the grey/green on the mk1 loom

Jack made a guide up, look in the articles section, I've never changed a mk1 to mk2

[Jack]

As far as I remember, the headlamp is a colour-for-colour splice when using a Mk2 plug on a Mk1 loom. I'll take a look in Haynes in a bit just to make sure.

[edit] Just looked. Are you sure you've not got the heated RW/blower plug? Thats got the looped black wire on it, not the headlamp one.

[swedge]

Nope definitely the headlamp plug has a single black wire from it, ivve taped it off and everythings working fine apart from the rev counter

I wired the green wire forcthe rev counter and it worked fine took it for a drive and when I got back it had stopped working, I checked the wires and they were still connected

I went to the others halfs house and it worked for a while again but has stopped

does the green wire carry a voltage so I can test if it's the wiring or clocks

[swedge]

Anyone know how to test the wire forcthe rev counter?
