Honda SL-3 will not program (led wont flash 10 times)

Question

WE have an 06 honda odyssey and installed the RS1 remote start and followed the directions to install the SL3 bypass mod but when we help in the program button and hooked in the 2 wire harnesses as directed it doesnt flash.  The red light is constant once we install the 3 pin connector and then we'll put in the other connector pretty quickly, release the button and put the key in the ignition in the on position the led mainly stays constant or it has flashed constantly non stop.  Im at wits end.....  we checked all conections and rechecked and rechecked the wireing diagrams to verify the correct connections.  the van will crank but it just wont start.  we have ignition.  need help

Answer 1

When you turn the ignition on what is the voltage on the yellow wire? also what is the voltage when you turn the key off?

What wire in the vehicle did you connect the purple/white from the sl3 too?

Also how were the physical connections made? solder t-taps twisted?
