remote start in 98 Dodge Caravan.

I'll be installing a remote starter into a 98 dodge caravan within the next little while for a friend, I've already done one in my car and I Needed a bypass kit for it (98 cavalier) so before I go ahead and start into the caravan, I was wondering if anything is required, or if i should be able to just install it and go. or any relays or resistors that may be required.
