Today we installed the Avital 2101L remote entry system. The system was $44 on Amazon and an easy install. This system will work directly with the Essex Keypad. Attached is a copy of the system harness 18 pin connector layout and our coach old system and combined H1/7 and H1/9.
Lock button- Entry door and bays all lock at the same time.
Unlock button- opens entry door, second depression opens bays.
Working on setting up H1/16 Orange with a 5 Pin SPDT Relay to operate the step. Step will go up when locked and down when unlocked. We will report when this modification is complete.
Hope this helps any looking to do the same,
John M
