Generally, you can check the Help! section of your local and you'll find them there - they're repair sockets, and prewired with about 6" leads.
I've been having a little difficulty myself - I'd like to release a PnP headlamp harness, and I need to get the plugs totally unwired.
However, ampacity of a wire is a function no only of conductor cross-section area (wire gage,) but of length. If you're going to use it with OEMR (or equvalent) bulbs, then it won't be an issue. Otherwise, I'd probably not go past 80W or so with the "restriction" you'll get from having the smaller gage lead. However, I'd not expect it to be a problem for what you're trying to do (from what I can tell.) If you're going to go to 100W or more on any filament, it may be an issue - but with 80W or less, not so much.
