The pigtail/plug that plugs into the coil on my car, the wires starting to come out of it,I think thats my hesataion problem. I called the dealer to buy that pigtail but they said its not available..... does anyone have a toyota part number, or another solution? TIA!!!

If the plastic connector is damaged then that is an easy fix, but if the actual wire is coming out of the metal prong that goes into one side of the connector it may be more difficult.

I dont know if you can buy just the metal prongs that insert into the coil pack connectors or not.

you can, i ordered some a couple monthes ago

i think the terminal part number someone linked might even be it.

you need a soldering gun and 12 'terminals', and 6 housings.

i picked up new coilpacks aswell when i did it. im glad i did :p

i bought my car with most of my coilpacks connectors looking like that.
feel free to laugh then get mad, then laugh again. thats what i did.

also if your doing this stuff get 2 new PCV hoses for in between the valve covers. then thank jeff lange for tellin me that.

actually i dont think you will "need" 12 terminals..... but you might want those.

its not exactly easy to remove the old busted up connector housing from the terminals.

i know i tried to order just some prongs in the past from curt for something, but they only sell it as a solid wire with prong on it already that you would just solder back in place.

oh no, you can actually buy the plastic clips and slide the old wires in..

I was just stating that if you happen to need a metal prong / pin, they wont sell those by themselves and supply a small wire already crimped to them...

just depends on which you need.

I have 5 connectors that have about 100 miles on them and I have a spool of 500 metals pins. Hit me up if you need anything.

Ok so I've got the clips/plugs that connect to the coil packs. My metal pins that go inside the plug are still in good shape. How do you replace only the plug without having to cut the wire and solder on the new connector?

Good video.

To add, you can buy new wire pigtails from Toyota and other sources, but only replace them if absolutely necessary. What seems like a simple cut and solder is a royal PITA.

First off, the new wires are WAY thicker, so trying to twist two different sized wires together is not fun - the factory ones are puny. Then. since the wires are thicker, they don't tuck in the plastic loom as well as they used to.

Secondly, these wires have to make a U-turn to connect to the coil pack. So trying to cut the wires just the right length so one isn't pulling on your new connection is also fun.

Lastly, you are doing all of this while laying across the engine. Gives the back a real workout.

T6Rocket I agree its a good video. It looks easy enough to pull the pins out of the original connector with that needle.

Where do I buy just the connectors and not the pig tails or should I buy the pig tail and remove the pins/wires from it?

Any Toyota deailer. The Coil Pack Connector is part # 90980-11246, as shown in post #3. You don't need new "pig tails" if it's just the plastic housing that cracked. Once you get the new connectors, you'll see how they dissaemble and reassemble.

Ok so here was my solution to the problem:
1) The white insert that holds the two contact pins inside the harness plug (the plug connects to the coil pack) has the shape of the letter M, where the two contact pins sit on the inside of the letter's legs -- something like this ()\/() if that makes sense. You first remove the white insert by inserting a small screw driver (minus) at the base of the M and gently prying it out.
2) My harness clip was so old and brittle that I basically used a little force (after having removed the white insert) to pull out the two pins. I recommend you put something like a towel or toilet paper above the spark plugs while doing this because any pieces that break off from the plug as you're doing this, will fall into your spark plug opening and then you'll spend a lot of time trying to get that sheit out. Trust me, it sucks. REMEMBER the positioning of the two pins (white wire was closer to the clip side of the harness plug).
3) The replacement plug from Toyota comes with a new white insert. I was able to insert the two pins, which lock right into the new plug with a nice clicking sound. Then you push in on the front side the white insert and you're good to go.

Hope that helps. If your plugs break off, I'm going to guess that a mechanical joint (crimp) might be more reliable than solder because the latter will melt at high temperature.
