I need to know my options for converting my 4cyl YJ into a 1998 TJ fuel injected 4cyl. I have the complete engine and transmission, I just need to know If I can use any of my existing wiring or if it will all have to be converted to the TJ wiring. Are there any aftermarket wiring harness options? I don't have a wiring harness for the TJ yet and haven't done any wiring projects before and can use any advice you may have. Thanks, Jason

i think you will have to mod your harness or get a different harness as the newer motor will have more sensors and probably different sensors then the old one had
 

After I get the wiring harness for the engine the only problem I think I will have is plugging into the firewall. Then I have to wire the dash which I know will be a huge headache. Are there any websites that relate to this issue? Thanks, Jason
 
try googling it. there is a web site just for 4 cylinder jeep owners but i don't know the site name
