Default LT1 O2 sensors

I am sure this is posted somewhere, but hear it goes again.
I want to know if I can splice an Bosch type 4 wire square connector to a flat 4 wire type LT1 connector to wire my O2 sensors to a PSI harness.
I have the upstream O2 on my long tubes that have 4 wires. 2 white, 1 grey, 1 black. The PSI harness has a 4 flat type connector with 1 tan, 1 purple, 1 green, and 1 pink wire. Let me know if anyone has run into this or has accomplished this. This is a standalone type harness for a LS1 into a foxbody swap.

Are those sensors the same as the LS ones?

they are Bosch O2 that I had on my 1999 Ls1 motor that is going into the swap. This is a catless system and these are in the long tubes. They should be the same type and ground to the PCM the same way through the harness.
Just want to know if the is spliceable and what colors match each other..

This may help. If you can see this photo the 4 flat is on the wire harness, the 4 square is on the O2 sensor.
