I spent hours today asking about this. I finally managed to complete the task. To answer you simply, it's under the dash behind the ashtray. First, remove the ashtray. The lighter wire does not need to be removed, but may make it more convenient. Second, remove the ashtray mounting bracket( should be 4 7mm hex screws ) and the flasher is tucked behind the AC controls and may be even as far up as behind the radio. When I found mine it was loose, but the Haines manual I referred to said it would be held in place with a clip mount. Good luck.
