Hey everyone new member here who has been lurking around reading up for a while however now I finally need to post and hopefully you all can help. I have recently purchased a 1990 skyline gtst with an rb25 motor and trans swapped in. My question is does anyone have or know where I can find a wiring schematic for the wiring around the Ecu? I will attach the photos of what I'm dealing with and trying to sort out, thanks in advance.

Just an update I was able to pull the part number off the box and Google the part number, turns out it's the body control module...I wasn't aware that these cars being as old as they are had body control modules.

Are you also aware that the Haltech is not an OEM item?

Yes im aware I have done a lot of high horsepower builds in the past with other imports this is just my first skyline, so I'm well aware of what the haltech is and its capabilities. Sorry I should have included that in my original post :) appreciate the help though

Yeah I think you may right shoota...at least all the engine stuff is ran through the haltech just have to figure out the rest of the jumbled mess...I was unable to disconnect some and untangle at least

Just an update have come to the conclusion that this is the module for the automatic spoiler which has since been removed from my car. Will go through and remove when I start cleaning up the wiring here. This job has gotten pushed back as I need to do the water pump first, however I will keep you guys updated when I tackle this.

    • No, code 21 is very straightforward. It can only be the things described in that diagnostic flow. In fact it has no way of knowing that the spark plug resistance is out of spec.
    • Hi, SteveL Thank you very much for your reply, you seem to be the only person on the net who has come up with a definitive answer for which I am grateful. The "Leak" was more by way of wet bubbles when the pedal was depressed hard by a buddy while trying to gey a decent pedal when bleeding the system having fitted the rebuilt BM50 back in the car, which now makes perfect sense. A bit of a shame having just rebuilt my BM50, I did not touch the proportioning valve side of things, the BM50 was leaking from the primary piston seal and fluid was running down the the Brake booster hence the need to rebuild, I had never noticed any fluid leaking from that hole previously it only started when I refitted it to the car. The brake lines in the photo are "Kunifer" which is a Copper/Nickel alloy brake pipe, but are only the ones I use to bench bleed Master cylinders, they are perfectly legal to use on vehicles here in the UK, however the lines on the car are PVF coated steel. Thanks again for clearing this up for me, a purchase of a new BMC appears to be on the cards, I have been looking at various options in case my BM50 was not repairable and have looked at the HFM BM57 which I understand is manufactured in Australia.  
    • Well the install is officially done. Filled with fluid and bled it today, but didn't get a chance to take it on a test drive. I'll throw some final pics of the lines and whatnot but you can definitely install a DMAX rack in an R33 with pretty minor mods. I think the only other thing I had to do that isn't documented here is grind a bit of the larger banjo fitting to get it to clear since the banjos are grouped much tighter on the DMAX rack. Also the dust boots from a R33 do not fit either fyi, so if you end up doing this install for whatever reason you'll need to grab those too. One caveat with buying the S15 dust boots however is that the clamps are too small to fit on the R33 inner tie rod since they're much thicker so keep the old clamps around. The boots also twist a bit when adjusting toe but it's not a big deal. No issues or leaks so far, steering feels good and it looks like there's a bit more lock now than I had before. Getting an alignment on Saturday so I'll see how it feels then but seems like it'll be good to go
