Hey bud,
I'm the guy that wrote the write up on the E3 remote entry module programming.... I've never seen the module in an E1 but I do know it's not the same as an E3's one.. I've read somewhere that the module is in the drivers door of an E1 but don't quote me on that !! If you find the module and it has the same sort of switch (SET-FIX-SET) on it as an E3 does then it should be the same type of process, if not then who knows !!!!
Anyone else shed some light here ??
P.s. Here's a quick link to the thread so you can see the switch I'm talking about.
