Turbo swap wiring questions
I'm swapping an s4 tii into my s5 n/a chassis using a haltech 1500 terminated harness. My question is on the body harness (one coming out of drivers side firewall) if thats what it would be called, what can i get rid of ? do i need the fuel pump resistor relay (haltech controls fuel pump?). and the little pressure sensor that bolts to the passenger strut tower? im sure ill have more questions, i just started putting it back together but i want my engine bay to look decent.

I’ll just start with a short comment and say the crank angle sensor wiring exists on the chassis wiring coming down from the driver side engine/chassis harness.
basically I’m saying the stock ecu has 3 connectors. 2 for the engine harness. 1 for the chassis which has the wiring for the crank angle sensor.
id assume fuel pump signal exists in this same connector.
Edit: I’m thinking of the opposite side of the firewall from you, so you should probably disregard my comment.

I have a rewire kit which I planned on using to bring a higher gauge to the pump. The haltech has a plug for cas if remember correctly. Im most likely not going to need that fuel resistor. And I believe since I have to upgrade to bar map sensor I can get rid of the stock n/a sensor. You have rhd I’m assuming ?
