HR31 wiring issue

Hi all, having an issue with my HR31. Bought it a while ago and the previous owner had chucked a Silvertop rb20 in it. Wiring is pretty dodgy but it worked so I just left it. Motor ended up having low comp, so bought a rb20 from a ceffy. Dropped it in lost interest in it but now back working on it after a year or so. Connected everything up tried to start it and I have no spark, went over the whole car and found that my ECU isn't getting any power. Now the plug that sits near the power steering reservoir is plugged in and that connection is getting power, but LED isn't coming on, on the ECU. Here's the fun part, I have a lot of plugs down by the ECU that are getting power but they don't lead anywhere. Pictures below are of the plugs near the ECU, any help is much appreciated. Hopefully I've just missed something small or it's a fuse somewhere ect. Cheers

I don't know that anyone is going to have specific knowledge on this issue. (I might be wrog though).

As someone with a basic idea of electronics, it sounds to me like you're on the right track. Just keep following your 12V back to where you can. You might find its something super easy like a termination that needs repinning or a broken wire.

Silly question: Are you sure the ECU is good? What happens if you power it up with 12V from elsewhere?

      I'm normally copping my own abuse from neglecting my daily drivers. "Those suspension bushes will last a bit more", "Don't worry about the oil leak, just keep topping it up". The project cars I'm always doing things slowly on them as I'm wanting them to be done better, and neater, and nicer. Luckily I don't have to deal with 18 year old Matt's "Learning to wire" stuff in the project cars. And there's only one piece of wiring I'm displeased about in the Landcruiser, and it's about to be cut out... However, the box loads of parts that have been going through this place lately for the Landcruiser... Brake pads Brake Rotors Full handbrake overhaul Wheel Bearings Seals Swivel hubs Steering Boxes Half the suspension joints Shocks Air bags (Ones to go in the rear springs for towing) Water pump Timing kit Lower timing case Harmonic Balancer Radiator Lots of other little seals and shits Gas struts for the bonnet New power window switches And god knows what else I've forgotten... Ha ha ha I have my fingers crossed the pinion seals don't start leaking on the diffs, that the transfer case doesn't leak, and the gearbox input shaft doesn't leak, nor the rear main seal. As they're about the only seals I haven't replaced in the driveline! I'm seriously eyeing off buying new caliper rebuild kits front and rear brake calipers... I'll probably recheck all the valve clearances soon too, and hopefully, it should be all good and sweet to haul some long distance trips again!

      Every time I pull my 3x gauges out of the console and see the crack-addict way that I did the wiring, and I just can't bring myself to tear it all apart and "make it nice", because it is currently working. In fact, the last time I was in there I probably made it worse.

      The best part is when you own the car long enough that you look back and find your OWN ham fisted amateur shit!

      The annoying part about neglect, is when you start to replace one thing, and find ten more broken things. Ham fisted monkey repairs you normally only find out about when trying to do something unrelated! Ha ha   Neglect you can kind of anticipate the huge costs to fix it all. Ham fistedness is normally a shock the first time your work on a new old car, as everything "looked" good before.
