    Thanks Jeff, appreciate the explanation. Glad to know what was going on. I tapped into the same wire in position #6.

    Anyhow, I pulled the device today, spliced the wire back together, and I had been running it without a correction factor in the interim - in the event that the signal was getting used by something (which it looks like it was).

    I've installed a hypertech unit that I bought new off ebay for $168. Compared to the Dakota and materials to install, it's about a $40 difference.

    I am about to go road test it.

    I’m curious to see if it works. The way I understand it, the hyper tech is just essentially a plug and play version of the Dakota, meaning it just intercepts the speed input and modifies it, which means it wouldn’t work. But I could very well be wrong. I’m learning a lot from this thread.

    Hypertech unit works well. The model number for the 2012 Tacoma is 730117.

    I didn't get the truck over 45 mph on the way to work, but compared to my GPS the speed is tracking within 1mph difference, the speedo is now reading a touch fast.

    Programmed the unit using the software that came by DVD. Using the stock tire size from my door jam and current tire size, it gave a correction factor of 1.07. Software will also calculate if you have non-stock gearing, mine are stock but, it's an option.

    Because tires are about 4 years old I'm guessing the diameter is a little smaller and I probably need a correction factor of more like 1.05-1.06 to be 100% accurate. I'm going to wait until I test it on the highway at higher speed to see if it is very far off before messing with it though.

    I did leave the USB cable plugged in and routed down to behind the coin drawer near the fuse box so I could reprogram if necessary with my laptop and not have to disassemble my dash again.

    As for the actual install - it is stupidly easy. There is a small unit that is programmed via the computer, it plugs into a circuit board, which has a slot for the wire harness and a second wire harness that plugs into the instrument cluster. There is plenty of room behind the instrument cluster to fit everything.

    Thanks everyone. Hopefully I didn't mess anything up sending the modified signal to my ECU and ABS. I did read in the Dakota instructions that the signal should not be going to ABS... That said, I don't appear to be having any issues.

    Damn, really appreciate the work and info you guys put into this thread. Hoping I got this all correct, but, it seems that the Hypertech would be the way to go for my 2015 4.0, automatic.

    If you read back a little bit on this page, it appears it won’t work on 2012-2015.

    Bwthomas77 reply a couple above, it sounded like he had success with the hypertech

    My apologies, I skimmed your reply. I thought you said you were going to try the Dakota. You’re correct that the hyper tech will work well for you.

    yep, definitely want to go hypertech for your 2015. Mine is now spot on.

    Thanks everyone for a lot of great info. Definitely a learning curve from the diesel world!
