electric mirror help please

[2.5bluenob]

Hi Guys, i have recently fitted rover 45 electric mirrors to the nob and not quite sure how to wire them up.
The mirrors have three wires for the motors so i guess this means i need to find a switch with seven terminals on the rear? Also the mirrors have a heating element! do i just hook it straight up to an ignition live if the switch doesn't support? or do i need a resistor?
Cheers
Steve

Would it be worth getting the wire diagram for the rover 45 and use the parts from the rover?

[Green3R]

logical guess would be:

there will be 2 motors up/down, left/right.

so, 1 wire is common to both- wire 'A'.

'Wire B' will be up/down
'wire C' left/right.

You'd connect - to common, and + to wireB to go up,
reverse those connections to go down.

Simplest thing might be to get the switch unit out of the rover?

Lot of info here:

it looks like my guess is right- you can see the 2 motors get 1 leg commoned together.

connect a 12v supply across any 2 wires. If both up/left move then the remaining wire is the common.

I have already hooked the mirrors up to a batt before fitting incase they didnt work. Yep there are two motors in each mirror. and they share a live together. and if you switch the polarity it changes direction of the motor. So i take it the three wires from each mirror go to the switch along with a positive feed, so that makes seven? im just not sure about the heated part?

Hi Bondy,a wire diagram of the 45 might help, but i dont want to use the switch as im looking for something that looks a little nicer! and the rest of the loom i can make myself.
Cheers steve

that metro link would seem to give the info though it's a little confused
http://www.metropower.org.uk/media/howtoguides/ele... is the wiring diag.

Interestingly the text suggests that the heaters are always on- so wired thru ignition as you suggest.
I'd be tempted to include the in-line switch as-per diagram.

All I can say is, please document what u do with pictures etc so we can put it in Noble parts for others like me to copy

unfortunately ive done all the fitting and only need to do the wiring now, so im not sure how informative it would be.

I have just done this to mine, although not with Rover parts.

As you have found, there are 2 motors per mirror and the polarity the connections to each needs to be reversed to switch from Up to Down or from In to Out.

So yes, 3 wires from each mirror, plus a +ve feed, plus a -ve feed to the switch.

I am pretty sure that all switches will work the same way so I would suggest you get the switch you want to use and then take it from there.

You can run three wires from the N/S mirror across to the O/S in readiness, together with the +ve via it's own new fuse and a -ve.

I didn't bother with the heated elements so can't help with that.

Regards

Graham

ETA : Forgot to say, the common wire on each mirror gets joined together and goes to the one terminal on the switch - at least it does on mine - so the switch has 7 terminals.

do they look the same as the stock noble ones ?

Do you mean what I have done to mine? Or the Rover 45 ones??

No matter, mine are very different

(I gutted a set of the Carbon Ferrari ones and converted them to electric with Ford internals and switch )

thanks, that is quite helpful other wise with the negative it makes eight.
Not all switches are the same as i already bought a nice one that once opened up i found only 4 terminals! Gutted!
I did some reading and found that some clever systems use only one motor in each mirror with the capability of vertical and horizontal movements.

I'm planing on wiring mine up next week using a ford switch.
Does anyone have any photos or a wiring diagram to save me trying to figure out what colour wire does what.

This is what I used
