LS swap gauges - 5.3 swapped 1982 k5 blazer

[funderburgh22]

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?
Coolant
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?
Speedometer
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!!

Oil Pressure: I used the oil pressure sensor from the 90 and used an adapter, I don't remember which one.
I got this kit and used whatever fit: https://www.amazon.com/gp/product/B075RW533W/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&psc=1
Coolant: I have 2, the LS on the driver side of the engine where it was when I got the motor, the second on the passenger side to the rear, I used the 90 1 wire sensor just so I had the gauge.
Speedometer: Yes, wires are even the same colors. Or they were on mine.

Yes the third wire will work for your Gauge.
