    unless it was specified with them you wont have any wiring for it, but if you want OEM colours:
    black - ignition live
    brown - earth
    grey/blue - illumination
    green/black - oil temperature

    there was no factory installation for oil pressure, but in the corrado/scirocco/cabrio the wire is either blue/yellow or blue/white

    Thanks I thought the mk1 golf gti came with dials as standard. The dial holes were cut out to fit a tape player when I purchased it 25 years ago. Trying to put car back to standard. Thankyou for help

    I think your right. There is no wiring for them. Is it difficult to wire up second hand ones. Not sure if there are any senders for them

    you'll need an oil pressure sender to match the range on your gauge, preferably get a 2 pole type then it replaces one of the oil pressure switches.
    for oil temp if you also want the MFA to work you need a T piece so you can add a 2nd sender for the gauge. if not you either use the old mfa sensor or replace it for another one again depending on which oil temp gauge you have. the 0-170 audi ones need a blue sensor, the 0-150 ones often work with the original mk1 oil sender.

    then wiring wise the hardest part is running 1 or 2 wires from the engine bay, there are a couple spare holes in the bulkhead so its not that bad really. then the gauges need ignition live, earth and dash illumination. where you get your live and illumination feeds depends on what fusebox you have, ce1 you can go to g spade 2 or 5, ceramic g spade 3. illumination on ce1 you often have a spade grey/blue spade wire you can use. if not tap into ciggy lighter or radio. earth just goes to claw above fusebox :)
