maybe shoebox can help, im looking for a diagram for a 94 computer harness, im trying to convert my 99 ls1 harness into a plug and play for a lt1 car, and i found the 95 harness but im wondering if anything is differant? if it is can i get a link to it?
thanks

 

I think you'd be better off starting with an LT1 harness, don't you?

 

Without looking it up, I can't think of anything different on the engine harness between 1994 and 1995, besides the location of the oil pressure sensor on early 1994s and the plug on the end of the optispark harness. They use the same computer.

 

ok, well mostly the differance in the c*** connctors near the bcm, im going to track them back to the computer, and do the same on the ls1 harness and swap them so that the tach output is in the same part of the c*** connectors, and do the same with the connctors on the fenderwell

and no you cant use an lt1 harness it wont work with the ls1 computer...alot more work, i should only have to swap 15 wires or so...if that...just need to make sure the tach, the oil pressure, temp gauge? battery gauge and the speedo is in the right place
i hope im on the right track.......the fuel sending unit is exterrior to the computer harnes son lt1 so thatst not a problem, the temp gauge i think is also exterrior but im not sure if the ls1 has 2 temp sensors like a l11, if not ill just put one in the radiator hose...
