Just completed a 5-speed swap into my 02 tacoma. It runs and drives but 4wd (the front ADD diff) will not engage and the light keeps blinking. I swapped out the push button case behind the auto for a j-shift case as well. I spliced the neutral safety switch wires together to make the truck run due to the automatic ECU. I also wired in the transfer 4wd position switch from the push button case to the side of the j-shift case so that shouldn't be an issue. The push button trucks come with a separate 4wd ecu to control the ADD diff that the j-shift trucks don't have as well. I am not good at understanding wiring diagrams so I was hoping for some help. Here are the diagrams. Thanks!
