Im using the computer from a 2000 camaro and the wiring from a 2002 chevy pickup my question is do all 4 lo 02 wire blue connector wires 25,26 28, and 29 splice into each other or are they each seperate to the computer

 

the truck and camaro harnesses are done a little differently when it comes to the O2 sensors (ran into the same thing on my install). each O2 sensor should have its own wiring to the pcm

according to factory specs:

B1S1 - High (PPL/WHT) 69, Low (TAN/WHT) 29
B1S2 - High (PPL/WHT) 68, Low (TAN/WHT) 28
B2S1 - High (PPL) 66, Low (TAN) 26
B2S2 - High (PPL) 65, Low (TAN) 25

all share power (pink) at the same fuse
all share same ground (black)

 

I also was wondering about this when I tore my '01 truck harness apart a couple of months ago. thanks for clearing it up 1ADan, and thanks for asking rock861261
