the 95 and 98 ecu is different. if you swap the engine hope you have the ecu with it too. I have a 98 T100 5 speed 4x4 ecu if you need one. I pulled it out because I decided to run a stand alone because i put in supra injectors, 255 walbro full pump and a supercharger. so i redid the whole wiring harness for that. lots of work, but fun to do.
