What was the purpose of the maf sensor wiring mod?

Thanks for that, Cully. Were there any symptoms in how it drove besides the eml?

the ECU is a 362 one plug variant
planet listed the codes as
P0101 maf temp inconsistent Positive Break or short to earth
P0122 tps circuit 1 inconsistent Positive Break or short to earth
P0220 tps circuit 2 inconsistent Positive Break or short to earth

planet could reset the eml but it would return instantly
Running MAF unplugged on these ECU shows no EML

i did also meter out the signal lines from sensor plug to ECU Plug to prove they wernt broken,
i also metered the Earth paths while faulty the resistance to chassis earth was up to 5-6 ohms
once finished the same paths were down to 0.20hms

with the fault present the car drove like normal no oviouse side affects
once the modes were done and EML reset
the maf plugged in car would run with lack of power
unplugged the MAF power was back (typical test for a faulty MAF)
