Does anyone know if there is someone out there making aftermarket engine wiring harnesses for the 3.0's. Thanks, Woody

an entire harness? are you trying to find one for a swap? If you just need an oem harness, I am sure hte dealership or a wrecker would get you one....

I am looking for the engine portion of the harness (At least the part that connects to the fuel injectors and knock sensor). My wire harness is old, brittle and the insulation is coming off the wires exposing them to the environment and corroding. I installed a new knock sensor due to bad code, still getting the code that it is bad. After looking at the wires they all appear to be falling apart.  I called the dealership and they said they can not get it, that it is no longer a stock item. Thanks, Woody

LCE makes a standalone kit for the 3vz. I converted my knock sensor to a GM one. It required a resistor inline, but haven't had a problem in years. I am saving cash to get the standalone kit from LCE it is a big add on and power gain for the 3vz  .....I also tried to get a new harness......good luck on a OE one

Check craigslist for your area, an '89-'91 truck should be the same.  You might give Off-road Solutions a call and see if they are willing to wire you up a new one, they make the conversion harness for the 3.4 swap.
