I know OFFICIALLY this is a no go... however I read on another forum to test them you can by applying 12v+ and ground to two wires directly and they work. I then thought that they must be a trigger wire to make this work.

So in my head (with no evidence) wires going to each of the steps would be +, - and Trigger.

I was thinking you could link the trigger up to the puddle lights as these come on when the doors open.

Can anyone tell me if I'm sounding like I'm onto something or if I'm way off base here?

Cheers

What triggers the steps to go back in when the door is closed???

The motors are easy, its the movement limits that could be your problem, instead of limit switches the control module will probably have inbuilt load sensing and cut power.

I'll have a look at mine, I'm picking a kit up from LR later. Current

I was thinking I could use I timer relay to stop them and start them possibly?

Why would it be a 3 wire system ?

I would have expected 2 wires with the polarity being reversed to retract them again.

Some kind of timer and some kind of limiter to cut the power once they are fully deployed/retracted.

I am speculating from a point of zero actual knowledge except thats how the trim tabs on my boat work......

Hmm I know this is bad as its massively off topic but I see you are in Peterborough - what boat do you have and are the trim tabs any good? I have a 19ft bowrider inboard which struggles to plane with a full load I have got hydrofoils on the drive but wondered If trim tabs were any better?

Back to the question in mind - I will have to have a think its an expensive mistake if it doesn't work unless anyone else can chime in...

Dan, if it helps , i've put the 2010-2012 deployable step install guide in the wiki.. ... - .- -.

I guess you can hijack your own thread.

I've had tabs on a couple of boats & they seem to work very well - for getting on the plane & also for reducing porpoising (or bouncing around in choppy water)

I used to boat in the UK, but mine lives in Bordeaux these days - Mastercraft X30

Excellent chers - nice car nice boat!

I have put smart tabs sx on mine work very well on 19ft maxum self adjusting fit and forget...

Nice - I will have to give them a go I think -

Back to the topic in hand - I'm mad or stupid I ordered the set for the my07+ Not sure when I'll have time to look at this but I will - it would be great for a full pinout of the control unit if anyone can help

These any good?

The motors have got 5 wires aswell.

Thanks - may I ask why you've got it opened up?

I am trying to work out if it sits on the bus or if I can wire the button the steps the live and earth up and find a trigger wire...

I did it the other day and was going to reply to you but totally forgot, the casing just has 2 tabs, pop them off and a door opens up and the board slides out.

It hijacks the info it needs from the medium speed canbus at the integrated headunit thats why the 10-13 model has a different module as the headunits talk different protocol. Current

If the motors have five wires I imagine they will have a hall effect sensor inside to feed info back to the ECU as to their position, makes it very difficult to hot wire them and get them to work right, you need someone to make an ECU to work with the earlier canbus or I think you will burn out the motors... Pete
