>Aaaaaaaargh I hate wiring.......where's a beer!?

Are you salvaging the old wiring harness, or building a new one because it has to accomodates a different engine than the GT4 'stock', and if new, does that info exist in the shop manuals, or some other place? Wondering why you 'hate' wiring, considering that you take whatever time is necessary to do EVERY job on your rebuild. I can imagine reasons to dislike wiring, but wonder what it is to you that makes it an unpleasant job, other than your desire to 'get her done'.

Also, I wonder how others approach the job of creating a new harness, since there are so many wires and connectors involved, and it must require a systematic approach.
I decided it was cheaper and easier to use the old harness, purely because I know it works and there are no faults. A small bit of soldering which I don't mind. The only reason I hate wiring is when things go wrong.....faults can be hard to detect.

Seats and carpet in smile.gif



I can sit in it now and make "brum brum psssssst" noises.

There will be a full dash going back in, just need to get it all painted etc now.



Looking good.



Good clearence with the roll cage, even with the seats as far back as they will go smile.gif



Brum brum.........yes yes, dont laugh, I hate having my photo taken at the best of times.....but theres a face that says "If my wife takes any longer to take this photo, my smile muscles are going to give up"



Time for a well earned rest, got some decorating to do. might give this project a rest for a couple of weeks and catch up on the household chores.

Time well spent!!

Well that's been a frustrating couple of weeks. I managed to retro fit an OEM alarm from my GT loom onto my GT4 loom which was a right pain to do. .....but I decided after all of that (2 weeks work) to scrap it, find a normal loom and fit a modern alarm with a proximity sensor, auto unlock, total closure system etc...sigh. At least I learned how to rewire things and repin Toyota plugs......and never again biggrin.gif

I also got a load of zinc plating parts back, just waiting on a delivery from the Toyota dealers to arrive so I can crack on.



I have approached MK Autos https://www.facebook.com/pages/Mk-Auto-Repa...121507894641634 about getting a 5sgte built in the not too distant future so getting towards the final steps and spraying the outside smile.gif

Re: Your comment about your photo:

The look I see in your face is that you are proud, pleased, and a little tired! That thought of taking time off might be a really good idea, considering how far you have come, how little you have yet to do, and not wanting to let yourself get sick from the stress of seeing that end point always coming, coming, coming. What you have accomplished in the past month is extraordinary. Take a little time off to replenish your vital energies so you can savor each next step and stay in the process just a little longer. Once you are done, you are done, with nothing to do but look back at the result of all that work, as you move forward to total your costs. There is something soul-satisfying about the work itself, right? When you are close to the finish line, you may want to speed things up, and that can lead to frustration.
So that's what you look like.

I'm dealing with messed up wiring from the previous owner in my Celica. Throttle position sensor supply voltage was hooked up to an unused pin on my ECU. Fixing that made a huge difference it engine happiness. I also re-wired the stock boost controller so I could mount it in a more accessible location. Why did Toyota put that thing on the back of the engine? Of course, now I thinking about replacing it with an electric controller. I preferred the rush of power from the unlimited boost I was getting from my broken manual boost controller. I want that feeling without hitting the fuel cutoff.

I've learned a lot about the how these cars are wired so if you have any questions, feel free to ask.
Thanks Antoine, I will do if I get stuck. Moving away from electrics for the time being. I won't be able to collect a new dash loom until the week after next, hopefully in the meantime other parts will arrive, and I will put the fuel tank on, finish the brake lines, fit some new discs and pads. Although I think tomorrow's task I will be a carpet layer or seamstress smile.gif when I re carpet the rear of the car which arrived yesterday.

Placed an order for some moulding latex so I can have another go at making a clear high level brake light lense and I also need to break out the fibreglass matting as I need to make some speaker boxes for the rear to help with the sound quality and to help relocate the speakers as I had to move them because of the roll cage.

Also do some more sanding on the front and rear bumpers as I made a start on them at the weekend.

bit of a note about the front flexible brake lines. there is a right and left line. I put mine on backwards then realized and had to swap them. the part connecting to the caliper bends at a different angle for each side. it's a tiny difference that's easy to miss.

The odd but of progress, I have been doing some design and preparing stuff for the engine rebuild. Getting more parts zinc plated, redoing wiring, battery relocation and basically waiting for the dashboard to get finished.

More parts in the engine bay, pretty much only missing the engine now, and a few radiators smile.gif

Is that a TRD engine mount?

1995 GT::::Diffusing the Situationエキサイティングカーレーシングチーム!march2010 COTM:6GCfeature2014:january2015-2016-2018 COTM
No, it's just the standard ST205 engine mount.

My Facebook GT4 Build page.https://www.facebook.com/groups/GT4Rebuild
What's the bracket above the mount for ?

Its a brake stopper, helps reduce the flex on the vacuum chamber under heavy braking.

time to refurb my spare rear diff, although i have fitted one to the car already, i am not happy with the amount of effort i gave to refurbish it, basically just a coat of paint over the top. I decided i needed to completely break one down, de-rust it, ft new seals etc. get it as good as i can before fitting it to the project car.

Mid breakdown, plenty of rust to go around biggrin.gif



the insides look pretty clean and not too worn out thumbsup.gif



Broken down ready to be either wrapped up to avoid contamination, or to sit is Deox C rust eater.



as well as some parts being sent away to the zinc platers 8)

So much rust for such a young car. redface.gif

The diff came off my old faff, it is 21 years old, remember the UK isn't the sunniest of places smile.gif and they salt the roads at winter time which doesn't help the longevity of any car frown.gif

Yeah, salt is killer on cars. I'm glad the stuff never hits the roads around here, even when it does ice over they use sand. You'd think in this day and age they could invent some kind of coating to put on roads that'd make them hydrophobic.

Oil?! rolleyes.gif
That's not permanent or safe. redface.gif I'm sure there're people that've dedicated their life to finding something, but it's either too impractical or too expensive.

bravo for such an awesome job. how much power are you planning on making? are you upgrading injectors?

I got rid of this resistor pack and re-wired the engine harness to support high impedance top feed injectors.



I bought one of the 3rd gen rails on ebay and it worked perfectly. just an idea. engine bay will be cleaner with less clutter in there.

Not sure what I will do with injectors? It there for the time being so I know where it goes, if I go with high imp injectors then I will remove the resistor pack. How easy is it to rewire?

Which component is the resistor pack, and can you please explain the two different injector configurations to me. I am learning and love watching this thing go back together.

it was actually really easy. if you look at the wiring diagram, the resistor pack is a single wire in and 4 hot wires out. all you have to do is take that single wire in, and use a jumper block and split it to the 4 wires, removing the resistor pack.

Oh. That does sound easy...even I could manage that 😀

I dont like to harp on about Bilt Hambre Deox C.......but by god its good stuff.

Before



235000 miles of crud and salt etc

and after 2 or so weeks in a bath of Bilt Hambre Deox C (and some minor wire brushing to help it along.

You know what also works, vinegar. tongue.gif From reading the specs on the stuff it sounds like it's just super concentrated acetic acid, which is what vinegar is comprised of. Since any other acid I can think of off the top of my head is toxic and isn't bio-degradable.

2001 Miata LS 5-speed
I tried vinegar, it works on mildly rust parts but nowhere near as good as this stuff,, plus this stuff isn't acidic as you can put your hands in it and cuts don't sting. If it is acidic it's very mild.

I also tried coka cola, pickling vinegar, 5% acetic acid, all the things that people recon works "just as well" and non of them do. It's also cheap, buying 20 litres of vinegar wouldn't be that much cheaper.




Although vinegar does taste better. Sprinkling Deox C on your chips would probably taste revolting.


Hmmmmm chips. smile.gif
