The PDC for '98 wranglers has a relay for electric fans but since no Wrangler had one my FSM shows nothing more then the relay location but 12v is there for the input.

Oe aux electric fan has always been an option in Xjs. I run a 98+ in my 88.

Well I just looked again, I thought the leads were there but they are not, I was hoping for a PCM output for fan control but I guess it either not there or buried deeper then I wish to look (I guess if 2.5L 98+ XJs have the option it might be possible). My main fan is on it's own harness currently but I though it would be cool to have it controlled via the computer with a manual bypass. I run mine allways ON with bypass because soo many temp switches have crapped out on me. :mad3:
