Does anyone know were i can get new fuel injector harness?

 

I would think that for something so specific, the dealership would be your only option. They changed the injectors over the years for these trucks so you will need the one for your specific truck. When I worked on my injectors, I had to special order the crush washers... If something as simple as the washer isn't carried by Napa or Autozone or other big retailers, I doubt any other company will sell them. If anyone knows otherwise, please correct me.

Either that or try and get one off a junker.

 

I assume your problem is the injector connector, not the entire harness. Take a look at www.connectorsfast.net (https://www.yotatech.com/forums/f116...ng-out-246773/) . I've never used them (my connectors are snubbed down with zip-ties). I suggest you get a very clear photo of your best existing connector to compare to their website before ordering. You'll also need to decide whether you order them with pigtails (meaning you'll have to splice each wire) or with crimp-on connectors (very professional, but you may end up shortening the harness too much.)

And most of all, you need to come back here, tell us what you did, identify the connector you used, and how well it worked.

 

I just got one at my local auto parts store and it was about $6 I think. Tell them the year and engine and they should have the right one in the computer system.

A few years ago I replaced all 6 on my Datsun and found a cool site online that had versions that you could pinch the sides to snap/unsnap (OEM originals you have to use a pick to pry the wire retainers open to remove...).

I'm in a head gasket replacement right now and my #1 injector connector's plastic just broke from being brittle - that's why I am replacing it.
