94 lt1 wiring verses 91 rs tbi

Hey fellows,
I have looked here for hours on this topic. I'm trying to swap a lt1(94 camaro)into my 91rs tbi. I would like to use the 4th gen wiring and tranny(auto 4l6e). What I want to know is what all is required from the donor car to tap into my current 91 harness. I'm looking for the 94color codes verses 91 codes and where to tap these into. I would also like to know about the computer I'm assuming I use the one from the 94? I'm green to this whole camaro thing so please forgive me if these are dumb questions. I just want to get it all mapped out before starting the pulling mission. I have a complete 94 z28 that has been wrecked pretty good. The 305tbi sounds like it needs bearings so its getting close to that time. I appreciate all the help you guys can lend me on this subject. Take Care, Kris

Hey thanks,
Could you point in what direction on that site I need to go. I seem to only find 4th gen cars or companys trying to sell me aftermarket parts. I'm sure its there somewhere but my internet time is limited with 2girls putting me on the timer, if you know what I mean.
