I'll install my updated WideBandCommander (now with analog 2 input). James from RWTD told me that it would be fine, when I would connect the analog 2 input to the pcm to read the MAF (The MAF signal wire is pin #88 from the pcm. It's a Light Blue/Red Stripe wire.).
Now my dumb question: Where do I find the pcm???
Please help, so I can install it tomorrow!!!

Lay on the passenger floor and look up above the kick panel with a flashlight. Also the main plug goes through the firewall behind the battery and connects inside. Hope this helps.

 

On the right side of the firewall (if you sitting in the truck) behind the battery you will see a wiring harness. Use a 10mm socket to loosen the bolt in the center of it. Pull the harness loose and up to where you can see it. Look for your wire and tap off of it at this point. This is where I tapped into my TPS wire for a cleaner looking install.

I didn't know which side your steering wheel was on so I described the location without saying passenger side.

 

I don't know if you all know this, but maybe I can help someone with this post I receive from James from RWTD, he got it from a friend:

'You can also get your TPS and RPM signal at the PCM wire harness. I looked it up in the factory service manual and tried it and it worked great. So all three connections under the hood are all on the pcm harness. No running wires to an ignition coil or to the tps.

Here are the pin numbers on the PCM plug:

#79 White/Red Stripe = RPM (ignition coil #8)
#88 Light Blue/Red Stripe = MAF Voltage (of course you told me this one)
#89 Gray/White Stripe = TPS'

This helped me very much.

 

Thanks a lot, everything is okay!!!
WBC works great and now James has to give his best!!!
