GM LS (GT 150) connector questions

How reliable are the factory GM GT150 connectors when used in motorsports applications? If there are issuses with any of them could i please get some input as to which sensors/actuators i should flying lead/pot.

Thanks

I've used the Stock GT150 connectors in a local touring car series with great results and no reliability issues. They're also cost effective so not a bad option. I have recently had issues with the 3 way GT150 connector typically used for pressure sensors but this may have been an isolated failure.
