2008 4Runner - KEY BYPASS Programming procedure fails, does not detect key

+1 vote
I just installed an EVO-ONE with T-harness on my 2008 Toyota 4Runner.  All 7 connections per 24121 have been completed.  The 20-pin white harness and the 6-pin T-harness are connected to the EVO-ONE.  When I attempt to program the Key bypass, it fails at step 5. The EVO-ONE does not appear to detect the key insert and the red led stays lit and does not start flashing.  I double checked all connections and they appear in tact.

The EVO-ONE is running the following firmware based on the recommendation of the Flashlink Manager software.  

Remote Starter:  v1.24

Bypass:  v79.54


Any ideas on what is causing this?

UPDATE here.  I figured out the problem.  The TX wire had a bad connection.  Hopefully this will help someone in the future.  

If not soldering the connections and using Posi-Taps, remember to test that the connetions have actually been made.  I had one Posi-Tap that was installed but was not making a connection on the wire itself.  This was easy to see once I tried a connectivity test from the source wire to the wire that was being connected.
