The Wires come out of the plugs by removing by popping the retaining clip on the front.
There are two different shaped ignitor plugs. One is more rounded than the other.
Some ignitors can be swapped between different ECU's but some will cause an issue. I recommend using to correct ones where possible.
To remove the cables some sockets have a plastic cover on the front. Remove this and it reveals a small retaining clip. Push the clip out while pulling the cable out the back. The other style doesn't have the cover so the clip is easy to see. I can do a video next week if you want.
I often have new pins for the plugs or for most of the plugs on the engine I have complete new plugs.
One big issue I see is the looms(harness) on these engine are 20-25 years old. Some of the looms I pull apart are in really bad condition. When I do an aftermarket I use all new plugs with new wire from ECU to sensor with very few joins.
Good Luck
thanks
yes, my loom looks like double ***** an incredible number of solderings
in it, but they are all strong, I have tested every single one for strength
my plugs (or sockets rather) do not have an "inspection hatch".
went to my fav, workshop in my fav. scrapyard today
got hold of 2 sockets with 5 wires in each, 10-15 centimeters long,
so plenty wire fr soldering
the chap showed me how to get the cables out
all for free
normally scrapyards charge 100 money a plug,
this is the 3rd time he gives me plugs for free, 5 in total
must remember to bring a 6-pack beer next time I go
a 6-pack is about 220 money, 5 plugs would normally be charged 500
that shop charges 3000 money for an ECU, most other shops charge 4000.

en passant:
in a post above I mentioned that I know of 2-3 really good electricians,
they have the full set of wiring diagrams for various UZs and they know
what they are doing (very very few electricians in Thailand know what they are doing, its all trial and error)
One of the guys have looked at my 1UZ 3 times. He has an interesting
way of charging. He charges 2000 money for his services 1 day, if he has to travel an hour to and from thats included- Highway toll is included.
If he fixes the problem in 10 minutes, the charge is 2000.
If he has to chip in a 10 bour day, the charge is 2000.
I asked him about this once. He said he is happy with this charging scheme,
in 90 % of the cases problems are sorted in less than 30 minutes.
And in far above 50% of the cases the problem is not electrical but down
to some ordinary car mechanic stuff.
