I have a set of quad tail light conversion looms, complete with diodes, grommets and plugs.
These have the original Toyota plugs so should be able to be fitted quite simply.
I've never fitted these (they've been sitting around since last winter) these have been soldered and taped but on inspection the quality of the soldering is really good and they test successfully for continuity, so I would expect them to be fully functional.
If not I'll refund in full (including postage) if the buyer pays the return postage cost of the items, however all the components are there so I'm sure it wouldn't take much to make it work.
I'll include all the bulbs as shown if needed. £28 delivered UK mainland incl PP
