I have a drive by cable truck harness and a 2000 TA PCM. What do I need to do to make them work together? Repin a few pins on the harness? If so any diagrams?

 

If you keep the TA tune you need to use a 2000 TA wiring, if you flash the PCM to a truck tune you need to use the truck wiring diagram

Your best option depends on what are you trying to accomplish

 

Its going to be retuned. Im running an e85 91mm turbo setup.

 

Ok, it's a engine swap?

If you already have the harness, it may be easier to just flash the PCM to match the year/vehicle of the harness, no need to repin.

If you are changing the wiring regardless, use the best operating system for your needs

 

I have the truck harness and Fbody pcm. I have a 6 liter turbo setup going into an fbody. Just thought I had to repin the harness for it to work.

 

So I can put it all in the way it is and tune from there. im thinking about using HP tuners.

 

Compare the 2 wiring diagrams to see the differences, there will be a few.
If the Fbody is the same year as the PCM and you need everything else to work (cluster for example) your best option is to keep the tune the PCM already has and repin the harness to match the car/pcm.

You can use it as is, but a few things may not work, like fuel gauge.

 

Its an all out drag car.Wont be running a cluster.

 

Then use it as is, if you have a problem flash a truck tune and be done

 

Will do. Thanks man
