As the title really, been busy splicing my cut loom on my 93 ls400 1uz and i have 6 wires left i can't get to the bottom of.
2 green wires, 2 yellow wires and 2 red with blue stripe.

Ok, i know one of the yellow wires is HTQ which goes to the oxygen sensor however this is difficult to continuity test so i would like to identify the other and do it by default.
All the other 5 wires go to pins on the three plugs near the ecu but that do not actually connect to it. What do these plugs do? These are the plugs on the pictures below.



Can anyone shed any light on what these plugs are for? Where they go etc. (They are 12, 14 and 16 pins units)
Soooo close now its sooooo frustrating :Eyecrazy:
ps sorry to anyone on a snail connection
