Replacinged the SKREEM??? Cathy that could be a real problem. Where did you get the SKREEM ??????
The #9 fuse will disconnect the "security system". Number 9 fuse is in the black box drivers side under the hood.
Before you do anything else answer the question about the SKREEM. There are only two maybe three places in the USA that can provide a working SKREEM replacement. WHERE DID YOU GET THE SKREEM ??

PS: DO NOT THROW YOUR OLD (ORIGINAL) SKREEM AWAY !!!!!!!!!!!!
