No worries, I'm pretty sure I've sorted it. I wasn't sure even which one the fan plug was, since I dumped the fan a while ago during the strip down.
Planning on doing a quick short of ECU pin#69 ;) to ground to confirm the fan comes on then it's another hurdle overcome!
So my ph1 headlights are in pretty poor condition including some internal adjustment mechanisms broken.
Most of the genuine ones you see online are also faded with snapped mounts.
There does seem to be places selling OEM looking ones brand new for a range of prices. Has anyone ever tried any...
Sorry, just realised that pin A5 on relay 234 goes to pin 2 on the resistor so doesnt actually go through the resistor. My comment regarding not understanding how you get high power fan on ph2 is void. Interesting that they did it differently on the ph1 and ph2 for seemingly no benefit, maybe...
That is excellent @Brigsy Thank you! Studying this and my ph1 wiring I believe it looks like this on the ph1:
I am not sure in your image for the ph2 how you would end up getting a different fan power on the low and high speed settings if both are going through the same resistor.
Anyway, the...
Awesome! I am also trying to adapt to a comex fan.
Would I be right in thinking the plug with two wires going to a single terminal is the fan plug and the other the resistor? As marked up above? And to bin the resistor you just remove the sections I've crossed out?
Yikes! That's a big hole!
Bottom dash off unfortunately to access behind it.
I'm pretty sure there's stuff in the way of you try and get at it by just taking the top dash off but worth checking. Maybe you could cut away whats being to squeeze it through and glue it on.
That being said if it...
Hey, any input is appreciated! Knowing it's a resistor definitely helps because my theory does make some sense assuming it's just a dumb electric motor running the fan.
I'm not looking to fix anything though, I just want an easy two wires going to my aftermarket fan, that come on when coolant...
Unless it sends power via the resistor for a low speed mode and direct to the motor for high speed? 🤔.
I think the low speed mode was for low speed ac performance meaning I could just cap off the wire to the left plug and just keep the other going direct to the right plug.
very frustrating indeed, but still, the end product is better for it! It still runs pretty poorly but I'm hoping that's a lot more down to the base map being all over the shop. Its definitely over fuelling hard, to the point that you can smell unburned fuel out the exhaust. I may contact EFI...
Does anyone know how the fan is wired up on these? Not sure there is a difference on the ph1 to the ph2 but I remember reading somewhere there is a connection for low speed and one for high based on AC demand. I basically have this:
Please enjoy my lovely sketch. But yeh, basically two wires...
