  1. I don't think the fuses will have minded too much with bit of water. See if they are blown which would suggest problems with the immobiliser. Is the immobiliser still trying to work out is there nothing when you try to use it? You could try bypassing it. That would involve following the wires from the immobiliser to the car wiring loom and joining the wires which have been cut and joined into the immobiliser wiring back together. Usually around the ignition barrel wiring. As for the rest of the electrics, you might have to leave it in the sun with the windows down to let it dry out. I have never pulled apart the fuse box before so don't know what could go wrong in it from water.
  2. The clunk might have just been it firing once. Check for fuel and spark. If both are good then we can look at what next.
  3. Ok.... Well first question, have you changed anything? What is different from last time it ran? It might be quickest to go back over what you have done and see if you made a mistake or disturbed something. Who knows how the wires have been joined. Second. What is it missing? Given you are playing with wiring it is probably electrical so let's check spark and fuel. Take the coil lead off the dizzy, position it so it's about 10-20mm away from a metal engine part then crank and check for a spark. Check the fuel pump is working by turning the key to ignition and opening the flap on the air flow meter. The relay next to the ecu should click and you should hear the pump run as well. As for the wiper, it could be unrelated. There is a control module in the tail gate which can play up if it gets wet which will keep it running. Let me know how you get on. If it ends up complicated you might need to get local help as problem solving without being able to stand in front of it to run tests really limits how much I can help.
  4. No need to remove engine to remove wiring. It can be a bit difficult to get to some sensors and plugs on the engine but definitely possible.
  5. Considering your wiring harness is the 20v one I would put it where it fits as it will not be quite the same. Normally the ecu sits 90deg clockwise with the plugs facing passenger side with the wires tucked up behind the heater box and through the fire wall. Tape them up tidy so they don't get damaged and hide them along the edge of the foot well under the carpet. If it all reaches I wouldn't worry about moving the ecu from where you have it.
  6. Your car was carby so they may not Have put the mounts in. It sits so the wires face the passenger footwell at the very top of your picture. It sits ontop of the gear cables almost wedged under the foot air vents.
  7. Don't stress it. Just identify one wire at a time. Label things, take pictures and buy a workshop book like a Haynes manual. The wiring diagrams are quite good. There are usually wires that are for optional items too so there will be ones not used. Just tidy them up to one side and don't worry about them. If you get stuck post back here and we can try to work it out.
  8. That could make a bit of a difference. You might be better off keeping the 20v fuse box. It still depends on which fuse box is emptier ąnd how the wiring was done. Time to do some investigation and see what the story is.
  9. It looks like the 20v fuse box is handling the main power and the alternator. I think I see the oil and water temperature or fan wires too. The 20v box should have a starter motor relay too which the 16v won't have as all the current for the starter solenoid went through the ignition switch. The ecu slides in from the passenger side and goes under the foot air vent sitting on the tunnel. If you have the brackets there are 2 studs it bolts onto. Try unplugging fuses, relays and plugs from each box and see what stops working. That's the easiest way to see where the wiring is at without opening up the loom to see what has been joined. If you need to look for joined wires It should mostly be sitting above the gear box as that's where the main Junction of wires meet from the motor, ecu and fuse box.
  10. It's hard to pick from pictures alone but I get a feeling there is not much going on in the 20v box due to 3 main plugs missing. It might just be there as the person doing the install was not confident with removing it. You might need to find where they joined into the wiring from the 16v loom to the 20v one and see what has been done. Without cutting up the wiring loom you can try unplugging relays and fuses from the 20v box to get an idea of what is running off it. Are there any wires from the battery terminals to the 20v fuse box?
  11. Off the top of my head it should be pretty easy to merge the 20v fuse box into the existing one. The majority of wires go through to the ecu and going from memory the alternator, starter, oil, water temp, rad fan trigger, ac, and I think a power wire go to or through the fuse box. The good thing is the wire colours are practically the same so with a bit of tracing and testing you can quickly figure them out. As for registering with an open air filter, I am not well versed but think the requirements are an enclosed filter. Just be aware that you do need to run the air flow meter with the factory ecu so unless you plan to swap to a black top ecu and wiring or an after market ecu then open throttles are off the cards.
  12. I can't help with finding the wire but Most Toyota tachos from that era use a high level input. Thay means they need a voltage spike off the negative of a coil to work. I had a quick search and it seems the Holden motor is a high level signal too so you might just need a tacho from a 6 cylinder Toyota and to find the right wire in the Holden wiring loom, assuming you are not running after market ecu and wiring
  13. Sounds like you might have some bad connections. Try starting at the battery then checking the earth wires in the engine bay, particularly on the gearbox and around the cylinder head. That's where the main earth wires usually are.
  14. I did this a few years back. You need to find the steering angle sensor and fit a normally closed push button in one of the wires. When you start the car and hold the button down for a few seconds the ecu sees it as a fault and disables vsc (you get warning light) until you turn the car off and back on again. Someone else might be able to confirm or tell you what colour the wires are.
  15. Without knowing anymore information I think you need to check how you wired the relay. Sounds like you might have the relay constantly turned on and be powering the air horns with the factory horn wire. Was it the aftermarket fuse that blew or one in the fuse box?
