Toyota Connectors

Field in Japan makes an ECM extension for the late model Supras, I don't
know if they make a similar model for the 3S or 4AGs, but it is essentially
a male and female connector with straight wires in between them.  We use it
to avoid hacking up the OEM harness for piggyback boxes (GReddy BCC, S-AFC,
ITC, etc.).  Also the HKS VPC uses a similar harness extension with a few of
the connections prewired for the VPC I/O.  All ECM signals are available on
the harness extension.

If anyone finds a source for these connectors, I'd like to hear about
it too. I've hacked up the wiring harnesses on 2 of my cars (4A-GZE
and 3S-GTE) to break out some signals, but it'd be so much cleaner
with the right connectors.

I did hear of a scan tool that attaches in this way, at the ECU
connectors. I can try to find out if it's a Toyota tool or
aftermarket... though I don't think in either case it'll help
us get the connectors they used.
