i'm trying to put in a magicar 8100 alarm/remote starter in my 93 eb. I'm having a hard time figuring out how to use relays to lock/unlock the doors. Is it true that the doors are the reverse polarity type? Iv'e got everything else working, but i need some help on the doors.

 

the motors may be reversible and they might have 2 wires and when you hit lock on the switch one is the ground and the other pos. then you hit too unlock, it works backward from the other way. I'm not good at explaining this stuff.

 

I do believe it is reverse polarity. Check this site out, it has some good install info for various vehicles. There is tab on that site somewhere with install tips that explains how to properly wire the reverse polarity switches.

Good luck!
