TOY: Fuel Injector Wiring Harness?

[Ed Wong <ewong_kaizen@xxxxxxxxx>]

Im not sure why you need to replace the connectors?
are they damaged or something?

RC sometimes might have them - ask them

The s'tealer sells the o rings individually.
Parts stores sell a kit. RC might even give some of
them to ya (the ones on the injector they give to you
- at least the last time I got injectos from them they
put on new O rings) The "cushin" that is used onthe
22RE motors is a parts store/dealer item. Its usually
dried out and melted on to the injector... replace ALL
of them - they tend to leak air into the engine.
(messes up the EFI computer's calculations)

As far as the EFI plugs - its not too hard to splice
new connectors on, but I would solder them on. The
problem with solder it that the joint becomes
"brittle" because it wont flex any more. when I did my
Lucas inj conversion, I soldered way back int where
the harness is a "bundle" so that it would not need to
flex as much. I had hoped to put "plugs" on so that I
could adapt the harness back, but I have up on that
idea when I saw how little room there was... Oh well I
save that project for the EFI swap (in my dreams).

Good day all.  I'm going to be removing the fuel
injectors on my 1995 4
Runner V6 and sending them to RC Engineering for
servicing.  I've never
taken the injectors off before so I've got a couple of
questions:
 1) Does Toyota sell a kit with new injector O rings
and seals or do I 
have
to buy each O ring separately.  Are there two O rings?
 One on the fuel
rail and one on the injector base?
2) I've looked high and low for new electrical
connectors that plug 
into
the injectors.  They're a special plug that no auto
parts stores carry.
Not even the specialty stores.  Apparently this plug
is exclusive to 
Toyota
and Mazda as they use Nippondenso? injectors.  Does
anyone have a line 
on
where I can get these round funky injector plugs
before I drop $200+ on 
a
new wiring harness from Toyota?
As always, many thanks.
