STS Machining (in the US) offers a flywheel machined for LH 2.4.

You might be able to find a machine shop locally who can adapt your existing flywheel for a 60 minus 2 trigger.
The TTV and other flywheel options have been mentioned already. But....
The ECU and EZ-K don't really care where they get their 60 minus 2 signal, as long as it gets one while the engine's turning. To that end, KL Racing offers brackets and tone wheel kits which attach to the engine's crankshaft pulley.

Just checked the Yoshifab site - their offerings are modified distributor fittings to fit CAS sensors for non-OE systems, not 60 minus 2.
Harnesses - I bought a 240 LH 2.4 harness made in The Netherlands from Dave Barton, and it's very well made with excellent documentation; it's not cheap though. It does have the advantage of being plug 'n' play into a 240. Time saved is money saved, plus reliability is priceless AFAIC, but YMMV.
Although in more recent times, @ramrod mentioned something about either making or supplying stand-alone LH2.4 harnesses - he may wish to comment on this?
Next comes the issue of chipping.... for another post.
