By standalone, I guess you mean hose fittings for both in and out? If so, then this isn't so relevant

, but I'll add it in anyway as it's a useful valve.
This 6-wire (or commonly called 5-wire) stepper idle valve (ISCV/IACV) is used on many 80/90s toyotas (eg: 1UZ-FE, 1G-GTE, 1J, 2J, etc).

Here it is pulled apart for curiosity:

It fits an easily machined flange if you want to incorporate it onto a manifold:

The step in the flange makes it a bit trickier to make, and is for an easily removed one-way valve to prevent boost from escaping off-idle with the valve cracked open:

It's pretty easy to control, as it has two center-tapped 12V windings, each one is measured at ~20ohm.

The connector is from the Sumitomo MT 090 family. Cconnector P/N is 6189-0029, terminal P/N is 1500-0110 (Small bucket), 8240-4828 (Large bucket).

It can easily be found at the wreckers, or if you want it new (for a very wide range of prices) start with places like:
