At this stage looking at mounting the module to the side of the dizzy housing and the coil rough where the current one is near the strut tower. Only problem is the need to be extend between the coil and module just hope the extra length won't cause problems.
I have remote mounted camira modules without a problem in the past, have them mounted in the vehicle cab. Just make sure the polarity is correct and they have a good heat sink.

The Toyota A340E auto box in my Calais has a TH400 speedo cable screwed into the side of it. When i did the swap was wondering what to do and it just connected straight up! Needed a small extension on the end of the cable but the threaded fitting was identical to a GM one. Am not sure what your mnaual gbox uses but would be worth checking out as you can get speedo cable pass through VSS's to suit a TH400 at most instrument places for around 80 bucks.
When you say make sure the polarity is correct are you talking about the input sign from the dizzy or the supply voltage. Main reason I ask cause I have know idea what polarity the Toyota reluctor wires are nor the Camira module. Referring to the heat sink there doesn't appear to be much on the Camira dizzy. Looking to just machine a flat the housing for the vacuum advance on the dizzy bolt up a piece of aluminium and screw the module to that. Would that be enough or do I need to rethink the location.
Interesting about the speedo cable I'll have to investigate. Do you know what thread the TH400 is and the drive size? I'm sure mine is 22mm thread not sure on drive size.
The polarity is the reluctor signal wires.. Here is what i captured with a usb cro from mine. As you can see the wave is not a sine wave, and if its plugged in back to front the module will trigger on the wrong zero crossing throwing your timing majorly out.
The camira modules are mounted inside the base of the camira distributor, so i'd expect that'd be enough cooling. In the next car Im building I plan to mount it on the metal on side of the engine bay.
Ok then I'll need to work work which way to connect it up then. Antus on your plot there how did you have that connected ie channel connected to the yellow or green wire so I can get it correct.
As to the A340E thread and drive, from what I have found it is the same as the T50 (my gearbox) but everything seem to imply the TH400 is imperial not a metric thread.
One more thing due to using $12P and plan to use the extra output and map switch where is the best place to get pin for the ECU plug? I've had a look in Farnell and jaycar with not luck.

I cant remember! I just opened the distributor, wedged a pair of wires in to plug and measured that - it was more out of curiosity than for a real reason. Considering you have a different distributor it may not follow the same wiring as mine anyhow. Maybe someone can suggest a better way but i think i'd just try it one way and if it doesnt start or runs really poorly then try it the other way.
yeah, when I was hooking up a camira module to my motorbike engine, one direction was very very advanced and backfiring, the other way was spot on. just try it either way, youll know which way is correct.
