1y Temp Sender Query 1 pin? 4 pin? drawing pin?

[dieseldave]

Hello,

Before I get flamed...

I've been trawling the forum and wiki since 8 o'clock this morning trying to work out how to get my temp gauge to work.

I've shorted the red and yellow wire and that seems to be all in order, gauge rises to the top...

The LED flashes and then turns off so I'm working on the basis the fluid level sensor is working ok...

I've recently installed a 1y 1.9n/a out of a seat Ibiza, the square holed circlip retained temp sensor on the water inlet/outlet hose doofer on the block between 3&4 has got a 4 pin connector on it could I connect the red/yellow wire to one pin and ground to another pin... if so how would I determine which pins to use and in an ideal world what would be connected to the other 2 pins?

or can I get a replacement 2 pin sender that will fit in the same hole? in which case does anyone know the part number?

On the old 1.6 block I've slightly different pipe setup and there is a sender with a connector on it that looks like a drawing pin...

There was a post I read by a scottish bloke either on here or brickworks that talked about a "drawing pin" connector but I can't for the life of me find it again...

I'd rather keep the seat pipe work in situ on the new engine as some of the old 1.6 pipes were damaged and it'd keep life simple...

Also can someone let me know what the single spaded connector is on the front (towards the passenger seat direction) of the block is? I originally thought this was the temp gauge sender but can't work out what it's for - it's got a yellow wire going to it)

A previous owner had put the 1.6 1y in (you've got to wonder why and there is fair evidence of "have a go hero" electrical work - scotch blocks and pvc tape in all directions... not that I'm much better but I'm trying to work out what goes where...

Any more light cast on the job would be a great help!

use the housings off the old engine that have the older sensors in them to match your wireing

would that just mean connecting the red/yellow wire to the "drawing pin" connector on the old housing?

Answer to above question Yes, (the drawing pin type connector) you simply slide the female spade end onto the as you call it drawing pin connector.
I run a 1.9 1Y N/A with a-- 1.6 JX wiring loom Colour Codes and were they connect to (Listed Below)
If yours was only a 1.6 CS N/A Then you will not have 1 extra wire, That is (1) Auxillary Water pump.

Yell/Red = Water Temp Gauge = End of Cylinder Block
Brown/Red = Auxhillary Pump. = Side of Cylinder Head
Blue/White = Glow Plug Sensor Temp = Side of Cylinder Head
Black = Fuel Cut off Solonoid
Yellow = Oil Pressure Switch (High) = Oil Filter.
Blue/Black = Oil Pressure Switch (Low) = End of Cylinder Head
Red = Glow Plug = Power Supply (No 4) Glow Plug.
All Browns are Earths - and shoulb be grounded to the inner engine bay compartment.
Hope this explains your wiring problems-----------------------
