ArthurH 7 Posted September 16, 2024 I'm building a new loom for our car. I'm retaining the original gauges, so I am starting with Zoldalma's excellent 'article' - Instrument Panel Explained - from 2002! Most of it makes complete sense to me, but I am confused by having two pins for the oil temp: A1 is the Warning light and A7 is the Signal. Can someone please expand on this? Similarly two separate pins for for the coolant temp and another two for oil pressure. Again, D6 is the Fuel level sensor and D7 is the Low fuel warning light. Are there two wires from the sensor?

welshpug 1,663 Posted September 17, 2024 other than the fuel sender each sensor is a single wire, earth through the body of the sensor, obviously with a petrol tank the fuel level sender needs and earth, and has the low level switch built into the same module. there is no oil high temp warning. 1 Share this post Link to post Share on other sites
ArthurH 7 Posted September 17, 2024 Thanks Mei. Apart from the fuel sender, that is pretty much what I thought. So, does the single wire from the oil temp sensor in the sump connect to A7 and not A1? 1 Share this post Link to post Share on other sites
ArthurH 7 Posted September 19, 2024 A related question... Does anyone know what current (or wattage) the starter motor solenoid draws? Obvs not the starter motor :-) I am finding dramatically varying results on the interweb when I search for this. Similarly, each of the two fuel pumps?

ArthurH 7 Posted September 25, 2024 Also :-) My rev counter connector (Blue) has one more connection than shown in the article above. Next to the rev counter wire in '3', I have a yellow wire in '4'. The labeling in the wire isn't very clear - it could be j28 or even T23 Does anyone know where this goes to? As it happens, I will be using an output from the Emerald Tacho driver module, but I still would like to know what this wire does. Share this post Link to post Share on other sites
ArthurH 7 Posted September 29, 2024 More :-) The plug on the Wiper motor has 5 wires. Black Red, Blue, White and Grey IIRC. Does anyone know what each of these wires does? Share this post Link to post Share on other sites
welshpug 1,663 Posted September 29, 2024 I believe they work as follows. Full speed. Slower. Intermittent. Trigger for park Earth. 1 Share this post Link to post Share on other sites
ArthurH 7 Posted January 7 Now that I have finally come to wire up the dash (having spent literally weeks on the wiper autopark ) I have discovered that my dash connector wiring differs from that posted by Zoldalma above. Many of the wires he describes are simply missing from mine, but I don't think mine has been modified or tampered with. Could someone please post a photo of the back of a Gti instrument cluster - but with the edge connectors still in place so I can see the wire colours?

ArthurH 7 Posted January 8 This is what my own dash and connectors look like: The fourth connector is grey (not yellow) but I doubt that matters. Zoldalma describes these five connections as 'Ground': A5, A10, B8, C4, D8. Where I am currently concerned, is that only one of those is present in my connectors. A yellow wire in B8 - which doesn't look like a ground. The Tacho connector does have a black ground connection at E3, but I doubt that is used for the whole cluster.
