Speedo, rev and temp gauge

Once this is connected up will the rev gauge/tachometer also work? Or will this just make the speedo work?
What do I need to make the temp gauge work? When looking under the bonnet I found a small wire that had a label with 'coolant temp' on but it was not connected to anything. This wire looks like it has come from ecu/fuse box area so what do I wire/plug it into to make the temp gauge work?
Sorry for all the questions but this is my first 'engine conversion' vehicle and would like to have the gauges working (speedo is quite an important gauge to have working )
Thanks for any help people can offer.
Also, my ECU is Qpeng management
Thanks!

red/yellow wire from fusebox is temp sender, how to make this and the rev counter work depends on what engine and spark control you have

Therefore would this speedo sender fit?

Anyway regarding that red and yellow wire coming from the fuse box for the temp sensor, I located it and there was also this wire:
It had 'coolant temp' written on it, was also red and yellow and had the matching connector to the red and yellow wire coming from the fusebox area.
I thought to connect the two up but the temp gauge still didn't work. Is it possible that they should be connected but a fuse has gone?
I also found a wire labelled 'tacho' that was not connected to anything…
And a cable that had come through the firewall near the fuse box area but was also not connected up to anything…

id assume yes the rev and temp wires need to join to the old wires on your mk1 loom, the temp will probably be the yellow/red you have, rev counter would be the old red/black to the coil.
earth the red/black wire with female spade, if temp goes to full yup you found the right wire. with the mk1 gauge to work on a mk4 coolant sender you need to put a resistor inline, what i recommend is fit a mk3 1.8-2.0 8v 4 pin coolant temp sender instead, changign the coolant temp plug to match. but it depends how the loom was made, it may already have a resistor?
with the rev counter you need a tacho adaptor if its on the oem mk4 ecu, and one isnt already fitted. if its aftermarket it could be outputting a mk1 compatible signal already. again hard to know!
cant you talk to the guy who made the loom?

Where exactly is the coolant sender located?
It is on a Qpeng 'plug and play' ecu I believe
Thanks for all your help

Would this sensor work?

I would connect the red/yellow wire from fusebox to one of the pins, but what is the other pin for? Just a ground?
Thanks

it has four wires going to it, I think i changed mine for an early mk4 item so it will make the needle on the dash work.
will see if i have a picture for you
