I'm actually after the internal connector that mates with the harness connector for the Cruise ECU 90980-11422. So non-working is fine, the rest will just be junked.

Haven't been able to find a male/female set of connectors (20 pins min, 8 of which need to be the 1.8 II size). Ideally, would de-pin the 11422 connector, insert pins into new female connector, build pigtail with new male connector. Just can't find the damn thing.

Even have an email out to TE

So I think I've found a way to handle the connection to the C16 Cruise Control ECU plug ...

C16 looks like this, 20 pins used

Get one of each of these

That's a 20-pin female connector and matching male socket (albeit a pcb-mount version). Conveniently, it uses the same 1.0 II and 1.8 II pins ...

Can cut the male socket off the pcb assembly, trim the pins a bit, and voila, there's a plug that will go into the new female plug. De-pin the oem C16 female plug, put the pins into the new plug as follows. Two of the 1.8 II pins (C16-03/16) need to be cut off and replaced with 1.0 II pins, but they're just signals, not high-current.

Connect your various standalone ecu wires to the pcb-mount socket, cover with silicone tape, and this will now plug into the new C16-version-2 harness plug.

Harness ===== C16-V2/Conn-100745 << pcb-mount/Conn-100747 ===== standalone

You could even get another pcb-mount socket and use that to build a short adapter harness to match up the original C16 plug. This way you could go back to stock and plug the Cruise ecu back in without dicking around with the wires again.
