Wiring help

[stu28stu 1]

Hi All 

 

i have tried the search arch as I am sure it’s been asked many many times,

i am fine with the mechanical side of things however,

 

i am am putting a 306 1.9td into my 205 which was a standard 1.9d.

 

i am an idiot with electrical stuff

the td engine has far more connections than the 205 , 

 

all wires are on the donor engine really neatly and all that comes off is a wiring loom with 2 no round plugs , ( which were connected by lh head light on 306 )

how would I wire into existing 205 wiring ? 

 

Other searches he’s have just said it’s and easy swap and wiring is straight forward ,

 

i have removed over pas and air con if that makes a difference 

 

all help appreciated

When Welshpug fitted a 1.9dt to a 1.8d for a friend there was no wiring differences. The engines are mechanical pump, so just ensure no immob. on the stop solenoid.

My 205 has no where near the amount of plugs etc ,

 

the 306 engine has 2 going into the fuel pump 

vs none on 205 

 

will work out out how to post a pic 

[stu28stu 1]

So a few pics

Iirc when we wired it up we used the 1.8d loom.

 

You need to get rid of the immobaliser bits off of the 306 engine. The engine doesnt need an ecu to run, so everything is self contained. 

 

I.e. you give it earth, 12v and switched feed to start stop solenoid and it will run when it cranks.

[stu28stu 1]

Ok

so I said I was an electrical idiot 

 

so the connectors on the fuel pump are not needed just for immobiliser ,

 

so better to remove loom that is currently on engine , 

and use original 205 wires ,

I'll let Meirion confirm, but thats my understanding of it.

Well cheers for help thus far ,!!!

The pump you have in the pic, has an armoured immobiliser fuel shut off solenoid, you need to cut the armour off and put on a simple on off solenoid, about 15 quid on fleabay.

The armours a pain in the backside to remove/cut off. its held with security screws, I have had success  putting a small conventional masonry bit, the type with a braised tungsten tip, on the screw head and using a masonry hammer drill in reverse. NOISY!

Google lucas pump armour removal. the nets full of folk de-armouring lucas pumps.

Dremels/grinders etc

When you`ve done this, use the nice simple 205 diesel harness and the sensors in the thermostat housing need to match your instrument cluster. They have coloured rings on em for ID.

Oh dear sounds interesting!

 

so after fighting and getting into the pump I can just change the solenoid to a basic one ; Same as on a standard 205 diesel ,

just with a 12v live bolted to the top ? 

 

Only thing ink left to solve will be the speedo as this engine has a electrical Jobby and 205 was a cable ‘

 

so all other plugs I can just ignore like the 3 by the oil filler 

 

thanks for infom

[Ozymandis 97]

Yes the basic solenoids the one.

 

If your using any type of BE gearbox, put the 205 speedo drive into your new boxes final drive, its simple to do.

 

Use the 205 harness, you might have to change the odd terminal eg the starter may have a lucar blade or a ring,  the oil pressure switch may have a different connector etc

 

Are you using the diesels instrument cluster? If so you only need the left hand sensor (as you look from the front) in the thermostat housing, it triggers the stop light in case of overheating.

Yes will be using the original 205 d instrument panel ,

 

i have the stop solinoid too 

I’d too the left hand sensor , in the 3rd pic down is that the grey plug with red wire on top , just above oil cooler pipes . 

 

Im using the gear box from the 306 td donor , I just changed the connector rod arm 

from the z shaped one to one I took of the old 205. 

Did nt think to check if it still had the hole to take the cable speed sensor

4th photo down, the blue plugged sensor on the left is what you need from your old engine, it does the overheat light.

Gotcha great thank you , 

 

sure there will  be more electrical questions as I move on , 

will post some pics when it’s all done and dimma kit fitted 

 

 

[Ozymandis 97]

The sensor with the grey plug and a red wire in the 3rd pic is for oil pressure ,use the oil pressure switch out of your old engine to mate to the 205 loom connector, its a simple Lucar blade.

excellent many thanks !!!

 

I appreciate all your help to me sir you are an electrical Wizard !!!!!

[stu28stu 1]

So after 4hrs with a dremmel I have removed the stop solinoid and replaced with 12v one !,!!!

 

many thanks for your help

 

now change a few connectors and fingers crossed 

[stu28stu 1]

You were also very correct about speedo cable that was surprisingly simple to change over !

 

just a few minor things to do now and I should get engine back in over the week end , 

get the engine bay tidy , fit the intercooler then I can crack on with preparation of the body work.
