Igniter Rewiring Question! Help Is Needed!

[firehawk]

Unfortunately it seems that the USDM igniter cannot be used on a MAP 4A-GE as the method of ignition control is quite different. The AFM engine uses the simpler VAST system where the distributor triggers the spark directly and is overridden by the ECU to produce advance. In the ESA system used on MAP engines, the igniter is always triggered by the ECU and the igniter only controls coil dwell.

This document has some pretty useful information on the two different ignition systems used on early EFI Toyotas;

I'm pretty sure that the japanese bluetop igniter is the same as the one used here in Europe so maybe someone here has an extra one? You'll be needing a part that looks like this;
