Ive got a universal boot soloneid.I can reverse polarity so it pushes or pulls there is just two wires.Ive got the mk5 fiesta boot switch with 3 wires 1 earth 1 live and 1 for the light.The soloneid is mounted got it all working just need to sort it now so it runs off the switch.Any help would be great because its doing my head in

Ground one side of the solonoid, power the other side from the switch. The switch should have an input, and an output when pressed. If you've got a test light or a multimeter it'll be simple to see what's what

Will it need a relay

i fitted a switch to my fiesta, simply took the power from the radio to the switch via a fused link, then from the switch via another fused link all the way to the boot via the roof lining from along the a pillar

GVK.

I would wire it up through a relay to save the load of the solenoid going through the switch, as above you need to know what terminals do what on the switch you have, so you know if pressed which pin is an input/ output, use a ohmmeter/buzzer to test the switch then wire it up something like this..

The black wire that i thought was an earth might be a live its looped.Ive had a multimeter on it and I get a reading from all wires

one is earth
one is illumination
the others make the circuit when the button is pressed

Mk4 Rick

Im guessing the black is the earth because its looped for the light and the switch.Do I connect the live from the soloneid to the switch with a 12v feed as well

without going to the car i can't tell you mate, but apparently the earth is the earth, one is for the illumination and the other feeds the boot popper

it's too late to go and have a look now but if you can wait till the morning (and if the mrs doesn't take the car) i can pop it out and have a look which wires did what

Mk4 Rick

Cheers mate this one has baffled me lol

dojj

the car will be back in about an hour so i'll let you know then

i ain't forgotten

Mk4 Rick

Cheers mate

I tried doing it before but the boot kept opening even before I press the button.Ive earthed the soloneid and earthed the switch.I connected the live from the soloneid to what I think was the live the (black & white wire) and put a live to it as well and the boot opened with out me touching the switch.I even thought about adding a relay?

Mk4 Rick

Looking at this picture here everything looks ok but where do I put the live from the boot soloneid lol




85 is ignition lie 12v
86 is earth
30 is permanent 12 v
87a is permanent feed to boot popper switch
87 doesn't get used ?

But where do I put the live wire from the boot soloneid?

not the best pic but the yellow wire and green wire is the live feed to the switch

and when you press the button this powers up the grey wire

so in your picture, the top black wire gets power, and the 4th wire along gets the power when it's pressed

you don't need to do any other buggering about so chop the connected wire first as this is whats causing the problem

Mk4 Rick

Chop wich connected wire?and where do I put my live wire from the soloneid and which is earth

funkyboozer

Orange/yellow is ignition or accessory live. Black earth. Black/ yellow to solonoid.

The factory setup doesn't use a relay as the solonoid only draws about 10 amps at the most.

top left corner is live feed in
top right corner is switched feed once you press the switch
anything else you need to make redundant so cut the looped wire from the top left to bottom left as per the pic

also, have you got a continuity tester?

put it across the terminals and see which one does the pass through when you press the switch

Mk4 Rick

Ive got that bit now which bit makes an earth

dojj

you don't need to earth it, i think that's where you've been going wrong

you only need to power the switch (via a fuse) and then send the wire to the motor to power it

Mk4 Rick

Dojj im now beginning to question the wires on the switch.I took the multi plug out of the switch and ive got an extra to spades but not for the wiring.

Can I have an actual picture of underneath your switch for the wiring please.i got it off ebay I did a test on it and when I press the switch it moves.You have three wires running off the back of your switch looking from the picture.

dojj

i've got 4 wires running off the bottom mate, but only 2 of them are connected as i didn't want to chop the wires too short

Mk4 Rick

Dojj your the man ive done it.It was top left like you said and the power from the soloneid going to the black and yellow wire with the black loop cut.When you look at some thing for so long it starts to drive you round the bend.

Thanks for your help Dojj

glad you solved the problem, and look forward to many years of button popping boot openings

Thanks for your help
