scroll down and it has specific instructions for the 93-98 supra TT and a picture to go along with it. wire colors might be the same because the XS also has a red, orange, and black.

i want to get one for my 240, so i can run a little bigger gap in my plugs with the higher boost, but it says KA applications need to use an EMS with dwell timing modulation so i'll have to talk to enthalpy and see if he can change my ROM to do that or not or if i can just be ok without it.
