So, got my harness back in and tested everything with the ECU unplugged... Just wanted to make sure all the windows/mirrors/lights etc still worked fine. At first it looked like everything was working mint. My new waterpump for the heat exchanger turns on properly with a 15 second delay after start, all the EDFC wiring works good. Then i realised the interior dome light wasn't working when the drivers door was opened. I figured it would be something easy but turned out it was soo much more involved haha.

So turns out, it's actually been broken ever since i swapped my interior from prefacelift to facelift and i've just never noticed. The two different models handle their lights on warning chimes differently. My old cluster (prefacelift) has an overspeed warning chime on the back of the cluster which chimes when you hit 116kph (70? mph), and that chime is also used for lights on warning. Unfortunately the facelift models use a chime that's built into the integrated control unit on the back of the fuse box which doesn't have an overspeed function, so ofcourse the wiring is different, and my overspeed chime didn't work Sad

You can see the speaker on the back of my old cluster:



The good thing is, i can pull that off my old cluster and if i can find a way to mount it on the facelift cluster then everything works, the dome light, the lights on warning chime.... Except the overspeed warning. You can see the one yellow wire that connects the unit to cluster in the above pic. That wire actually connects to the speed sensor in the speedometer... So i pulled out the old speedo and the new speedo to see what the difference was:



So there's a couple of differences. Firstly though, i could theoretically just swap the old one with the new one. That would mean my overspeed chime would work, but because the prefacelift cluster reads 180kph, and the new one reads to 240kph the needle wouldn't display the correct speed anymore. D'oh! So you can see in the upper right hand side of the unit there's a little bent piece of metal on the one with the overspeed system, and the one on the left does not have it. It's a neat little device, here's a better pic:



You can see a little prong sticking out into the void, when you get up to speed that brass looking disc spins around and makes contact with the prong at exactly 116kph which closes the circuit and turns the overspeed chime on. Sooo cool.

So i could do a couple of things to make it work. I can use Hondata's AUX functions to trigger the warning chime at whatever speed i set (sweet). But it still wouldn't chime on and off like it used to (you can kind of hear it when i back off the throttle in an old video i found from the drags):

https://youtu.be/Fswj1kc6ioM?t=3m10s

So once i figure out what causes the intermittent on/off signal i'll use a relay with a signal from the ECU to trigger at a given speed, and then use the power from the intermittent signal to pulse the chime on and off.

I also got my quick release engine harness connector fitted up. Looks alright, i think i might use a foam backing so it still has a watertight seal against the firewall.



Also swapped my carpet out from a rather haggered black carpet to a red carpet that it hought matched in nicely with the fleck in the door trims, seats and steering wheel stitching.



So yeah.. Working on a few things at the moment.

Nice interior upgrades! I'd need better rear pre-facelift door cards as they're bitten by a dog. The high standard of this build amazes me every time I watch it Cool

I wish it was cheap and easy to ship, i can't even give away my old prefacelift door cards!

Damn Steve.. Looking good!
Love that overspeed chime thing, never knew the car had that, but then again, i am never driving at 160 mph.  Most i've done is 120ish.
Keep them updates coming!

Na it flicks on at around 70mph (116kph). And it's only some models that have it, i haven't figured out what trims or countries did/didn't get them though... Weird huh!

Some more progress on getting things working, because i'm using an ECU signal for my overspeed chime, and i'm also triggering my superchargers heat exchanger fan using intake temps, i had to add a couple of wires to the Rywire ECU harness. Takes guts to start modifying a 1500$ harness hahah.


​​​​​​​
There's a couple of blank slots in the rywire ECU plugs where the hondata outputs too, so i've added wires between the cabin harness and the ECU as you can see above. The cabin harness connector was full though, so i pulled out the two 'extra' wires that Rywire include in their engine harness and just heat shrunk over the terminals so they could be used again later if need be. I also re zip tied everything to make it look like it should... Nice and tidy:

COOL!
Yea, takes balls to modify an expensive part period!  hahaha!
