i have a 90-91 electronic cluster coming in and had a few questions about hooking it up in my ls swapped '82 blazer

Oil Pressure
can i use the ls oil pressure sender since the computer doesn't need it? will it automatically work with the 91 suburban cluster?
i have a 3-wire sender on the ls, can i use the 3rd wire for the gauge? will that automatically work with the 91 cluster?
i have heard the pcm is 4000 per mile square wave pulse and the speedometer is the same, so hooking up the vss from the pcm should automatically work right?

thanks for the help!!
