  1. Most tachos, work by connecting the pulse train input wire for the tacho, to the negative terminal of the coil, which was traditionally, in a CB dissy; simply connected to the points. You could try simply connecting it to the negative terminal of your coil. If that doesn't work, then try the IGt signal. That is a nice square wave, & has some dwell information in there, as a result of the width of the pulse, which will not make any difference to the tacho reading, as it is only interested in the frequency, of the pulse train.. I notice that the ignitor in the diagram above, does have a "TAC" output, but as there is no wire colours depicted, that may make it difficult to identify, unless there are some markings on the ignitor itself. If you had access to a CRO, or a multimeter, that measures frequency, then you could probe around, until you found a signal that changes frequency with RPM. Unfortunately, I've never come across one of these Toyota ignition systems in my travels, so don't have any personal experience. Strangely, when I built the ignition system in my KE30 Corolla, years ago, I instigated a similar system, where under starting conditions, the coil is sent a signal at base ignition timing, of 10-12 degrees BTDC. Once the engine is running, the ignition system, then switches over to the electronic advance system. It does have the advantage, that the engine starts instantly always; & if your ignition system ECU & ignitor fail altogether, you can flick a switch, & get on home, in "limp mode", with just the base 10-12 degree advance. Somewhere on this forum, I described this system, years ago. I'll see if I can find it. Here it is . . . . . . Cheers Banjo

  2. Man ! Is that complicated. That was leading edge technology, back 30-40 years ago. However, the risk, with getting this system going; is that if & when some component in the ignition system, fails in the future; there will be a very high likelihood, of not being able to source the spare part at all, to make it work again. I also love getting olde things working again; however, there is a limit. There are plenty of trigger modules etc, that will fit inside existing dissy's, such that it appears to be "olde school", but will perform much better. Now take this guy ! I watched this video recently, & it was painful, to watch His efforts. However, He got there; & that was probably all He wanted. https://www.youtube.com/watch?v=arxOB5u9kaE Then there was this one, which many of you have watched. 10 million plus views on utube, but I loved reading the comments left by viewers ! https://www.youtube.com/watch?v=1RX_AJRbYzc Cheers Banjo

  3. I'm not sure how similar these systems are, they must be about the same age. This is on my early 4AGE motor- Here's the theory- Here's the diagram- Here's what it looks like- and here are the colours on mine. One wire was cut off when I got it. As you can see, the colours don't agree with the diagram, Toyota were busy making a lot of different ignition/ECU systems doing the same work around the early 1980s I think, its always very confusing. I took my tacho off the coil negative. I've never seen electronic ignition on a KE70 so I'm not much help for you I'm afraid.

  5. I reckon the closer to 2030 and 35 we get the more watered down the UKs rules will get. I think public opinion of EVs is changing, all those early adopters have already bought one, everyone else doesn't want one or cant afford one. Lots of commentary in the USA on how they cant move used EVs off the 2nd hand lots as everyone knows they have costly risks associated, replacement battery costs etc, and you cant fix them yourself really, far as I can tell all the parts for teslas somewhat restricted to dealers etc. not to mention would you want to to try and fix them yourself, its like fixing an i-phone, possible but the change of bricking it is high and then you really are on your own as they prolly wont help you if you touch it. Everyone in AUS seems to get an elec car on leases as they have the tax incentive, and you can give it back before it needs any real maintenance.....im as DIY as it gets and I'm not lining up to buy a cheap tesla as its locked down and I cant even fix if I tried. One false move and the thing will brick itself in my driveway. The laws you suggest basically knock out an entire auto repair industry. people aren't going to like that. and how they can justify such things on the basis of environmental baffles the mind. Crushing fixable cars, moronic.

  6. T50 short-shift kits exist, there's one on mine, but I don't know who made it as it was on there when I fitted the gearbox. I don't notice it anymore, except for the 'Need for Speed' click-chick sound like a pump-action shotgun.

  7. With much trimming and fettling I got to a point where I was happy with the patch panel. So I tacked the new peice into place Looking along the edge of the bend it still needs some work but it came out ok in the end So the next task will be to make the corner peice.
