LT1 Swap: How do you hook up MAF?
I went to connect the MAF from my LT1 to the connector on the stock 87 lid and I ran into a problem. the LT1 MAF is a 3 pin connector, my stock MAF is a 5 pin. Is there anyway to splice my old sensor into the new? What did you do?

No and No. Im running the LT1 ECM and wiring harness but the MAF plug itself on the LT1 harness is a 3 pin, the receiving part of the MAF on my stock lid is a 5 pin.
I believe MAF was used on all TPI units until 1990, then they switched to SD.

for some reason they went SD in 90,
IMO MAF is a better,
but on a 3rd gen MAF was a limited 16kb file
when they went to SD it got a larger 32kb file, which allows for better tuning
