Boost sensor question

Boost sensor question
I'm finishing up my s4 n/a to s5 turbo swap and was wondering if I'm going to want a s4 or s5 turbo boost sensor. I'm thinking s5 to go with the motor. If that is so will it plug into my s4 n/a harness? From the pics I've seen it looks like it will.
Thanks in advance for the help.

You need to check if they need injector resistor pack or not, there were both versions available for S4 TII (low impedance injectors + resistor pack or high impedance injectors without resistor pack)
Everything else is same (air temp sensor, knock sensor, engine coolant temp...)

Cutting all of the plastic off the outside of the injector plugs will make them fall off easily. Did you leave anything to grasp the tab on the injector, or is it all gone?
All S5 injectors are high impedance, so you need to be sure the S4 harness you have is either intended for use with high impedance injectors ('87.5-'88) or has the injector pack plug bypassed ('87-'87.5). To bypass the pack, just jump all 5 pins together with some short wires.
